Security Fraud in Europe's “Quantum Manifesto”

While the manifesto is surely geared towards a specific audience (politicians) and contains a lot of buzzwords, the flagship project is very well thought out and supported by some of the largest research institutions inside and outside of Europe (e.g. including Intel, who invested 50 million in the QuTech centre in Delft).
The author tries to convey the impression that the manifesto and flagship project are the result of some undemocratic and misguided funding process, while in fact they are the result of many years of work putting together a proposal for this kind of project. This effort, which was mainly done by the scientific community, dates back to 2009 and earlier and has been a fully transparent and community-led effort.
The ideas behind the flagship project are very sound as well (in my opinion): Get different research groups in Europe to collaborate and share resources, provide a level of funding that allows those researchers to compete with e.g the US / Canada / Australia (which are all investing similar amounts) and get the industry involved to commercialize technologies where possible.
Also, qantum computing is only one of several flagship projects that have been selected for funding, the Human Brain project being another one.
All in all this kind of funding scheme in which scientists rather than politicians play a leading role are highly welcome in my opinion, and I would like to see this model copied around the world.
Concerning the potential overselling of quantum technologies: The limitations and uncertainties of this research were discussed very openly at the conference, and many speakers explicitly warned against promising too much to the public.
All in all I think all actors are aware of the fact that quantum computing / cryptography won't solve all their problems, but they still believe that these technologies might have a deep impact on the European and world economy in the next 20 years.

Are all those research institutions standing behind claimed security impact of their work? Were security experts and cryptographers involved, or is this just wild speculation from physicists as DJB's Theory 2 assumes.
I'm all for moving more EU money to basic research, but money can be moved to the direction I want with wrong promises.
The only mention of cloud computing at the conference was in the context of providing Quantum Computing capabilities over the cloud as a means to make these technologies accessible to a wider audience as soon as possible, as buying a quantum computer will probably be beyond the capabilities of most individuals / organizations for the foreseeable future.
Quantum manifesto lists many items that might be funded under the Cloud Initiative [2],
- Core technology of quantum repeaters
- Secure point-to-point quantum links
- Quantum networks between distant cities
- Quantum credit cards
- Quantum repeaters with cryptography and eavesdropping detection
- Secure Europe-wide internet merging quantum and classical communication
- Universal quantum computers will be available with computational power at a level of performance that will exceed even the most powerful classical computers of the future. They will be reprogrammable machines used to solve demanding computational problems, such as optimisation tasks, database searches, machine learning and image recognition. They will contribute to Europe’s smart industry, helping to make European manufacturing industries more efficient.

As far as my understanding goes the flagship money was distributed via an open propsal-based process, so I really don't see how this money was "stolen" from other initiatives, as the goal of this kind of funding is to let researchers compete for it by making convincing proposals.
The question is if the winning proposals made credible promises. Did the commission know it funded basic research without practical solutions in the sight, or did they read material like Quantum Manfiesto and thought there would be commercial and infrastructure benefits?
I'm leaning towards Theories 2 and 3: stupidity and marketing. Physicists who want to build quantum devices made claims outside their expertise and the commission didn't consult experts to verify these claims because it generally has no idea of what it's funding.
And concerning the potential risk of failure: Yes, everyone is aware of that. The flagship projects fund research, which means that there is a risk of failure and that we don't know all the details yet (otherwise it would be engineering). The funding bodies are fully aware of this and they do not expect that every project they fund will work out, but they know that today's research is tomorrow's revenue.
Even if the base research is successful, most experts agree that quantum communication is solution searching for problem. We can already transmit data securely trough bit-pipes using quantum resistant symmetric ciphers. Actual security problems are on different level (protocols etc.)
Because security-wise, according to djb claims in the original article (and Schneier too (2)), everything that the "quantum network" does can as well be implemented with the normal insecure internet and the symmetric ciphers, with the same security limitations (the secure channel, as per djb, initially is needed in both cases: "Quantum cryptography, like locked-briefcase cryptography, also relies on a preexisting secure channel (to authenticate choices of "bases" by Alice and Bob)" See also (1) ). So from the security standpoint it's a typical "snake oil" not improving anything but costing more, being much more complicated to maintain and therefore much less secure from the get-go.
"The Manifesto says that it is "endorsed by a broad community of industries, research institutes and scientists in Europe" and is accompanied by an online list of thousands of signatories; but the list looks more like a rather narrow community of people who are hoping that the Manifesto makes money for them, such as quantum physicists and their students. Security review, like environmental review, requires experts who are skeptical."
1) https://en.wikipedia.org/wiki/Quantum_key_distribution
"These proofs are unconditionally secure in the sense that no conditions are imposed on the resources available to the eavesdropper, however there are other conditions required:
- Eve cannot physically access Alice and Bob's encoding and decoding devices.
- The random number generators used by Alice and Bob must be trusted and truly random (for example a Quantum random number generator).
- The classical communication channel must be authenticated using an unconditionally secure authentication scheme.
- The message must be encrypted using one-time pad like scheme."
2) "Quantum Cryptography: As Awesome As It Is Pointless" https://www.schneier.com/essays/archives/2008/10/quantum_cry...
Under those conditions, all classical cryptographic methods fail (except one-time pad), because the attacker can just brute-force any key. That QKD still works under these assumptions is amazing in itself, and in any practically relevant scenario the limitations will probably not matter, as long as the key exchange is fast enough such that no decryption & manipulation of the classical channel is possible. Also, the attacker not having access to the decoding device is a reasonable assumption IMHO, as classical encryption won't do you any good either if the attacker has full access to your computer.
All in all, I think that the critique is justified but it is not something that will keep QKD from being useful in the field (I could be wrong of course).
Getting money from those who can give a lot can also be a valid economic goal, or in this case an accepted approach to funding (I quoted that Microsoft researcher) but using "snake oil" can still be seen as the evil opposite of the established principles of honest security engineering, the classic entry for Schneier's "doghouse."
The fair approach would be, "we're doing the basic research, no there's no too practical applicability of our research, but it's good to fund it anyway, that's why the research is different from engineering."
It would also let engineers do their work and not force them to implement less secure directions "because policy." Which is the effect that certainly appears here and there on the EU level.
There should not be "the other side". Yet there is no sign of security researches involved making these claims and you seem genuinely surprised that there is controversy and security researchers debunk the claims.

"Bennet, Bernstein, Brassard, and Vazirani demonstrated that quantum computers cannot provide an exponential speedup for search algorithms, suggesting that symmetric encryption algorithms, one-way functions, and cryptographic hash algorithms should be resistant to attacks based on quantum computing [4]."
(4: C. Bennett, E. Bernstein, G. Brassard, and U. Vazirani. Strengths and weaknesses of quantum computation. Special Issue on Quantum Computation of the Siam Journal of Computing, Oct. 1997.)
Note, this was already known in 1997, two decades ago.
After all the discussion up to now, I believe even more in djb's conclusion:
"Ultimately the victims are the users. A quarter of a billion Euros, despite being explicitly aimed at communication security, will actually be devoted to quantum technologies that are much less secure than modern real-world cryptography. The occasional users who can afford to deploy quantum cryptography won't realize how easy it is to break. Meanwhile a similar level of funding will be sensibly devoted to quantum computing, but without a proper acknowledgment of the resulting security apocalypse, and without a corresponding level of funding for the most plausible plan to prevent this apocalypse."
However it's sure that not only EU scientists make grandiose claims:
http://www.macleans.ca/society/science/trudeau-versus-the-ex...
"With a quantum computer, we hope to find a more efficient way to produce artificial fertilizer, having direct impact on food production around the world, and we hope to combat global warming."
Ugh. And cure cancer and make your pennies bigger. Hey it's quantum. Anyway Chinese already sell the "quantum diagnostics devices" comparably "amazing":
It's not about the "algorithms" it's about everything around them. The security is a strong as the weakest link:
Again djb, the original article we are supposed to comment here: "Fundamentally, quantum cryptography makes the same mistake as locked-briefcase cryptography: it aims for security in an oversimplified model of the physical world, takes resources away from more serious security techniques, and ends up damaging security in the real world. Quantum cryptography, like locked-briefcase cryptography, also relies on a preexisting secure channel (to authenticate choices of "bases" by Alice and Bob), and does nothing to address the problems handled by public-key cryptography."
See also my comment to "quantum credit cards" here as another illustration.
And why is it a bad thing to talk about applications that seem far-fetched today, like "quantum credit cards"? Blockchain-based currencies were probably also a pretty far-fetched concept 20 years ago, but today they have a fixed place in the currency eco-system.

Why? Because no sane attacker is interested in placing his probe between the laser and the card, but in the plain traditional electronics that controls the laser. If I were an attacker I couldn't care less that you send "a quantum state" with the laser in the card reader. It's just the plain classical bits on the level I'd be interested in.
To protect from that, you'd need the full "quantum internet" to every credit card reader! Which is exactly what djb claims is wrong with the "Quantum Manifesto:" making grandiose security claims that can't stand to the scrutiny of "classical" security researchers, as soon as the whole implementation is considered:
"an embarrassingly oversimplified model of the attacker that allows the attacker to inspect photons being sent between quantum-cryptography devices but that does not allow the attacker to interact with the devices in any other way."

and I'd also suggest the example of the other Europe's "big project" mismanagement, also mentioned in the Nature's article:
http://www.scientificamerican.com/article/why-the-human-brai...
I agree with the writer's opinions:
"The European Commission says that its goal is to "give Europe a global lead in the data-driven economy" so that everyone reaps "benefits of big data revolution". How could they have thought that this goal justifies putting massive funding (1 billion Euros, 15% of the total European Cloud Initiative funding) into quantum computation? Here are three theories:
- malice "If I tell them that quantum computers won't process big data then they'll take away money for quantum-algorithms research"
- stupidity "people could have been honestly thinking that quantum algorithms are important for big data, because they simply don't know any better."
- marketing "The European Commission actually has only the foggiest idea of what it means by "the Cloud" and "the data-driven economy." "Isn't even the tiniest piece of data part of the big-data revolution that surrounds us all? Join us in relabeling your research with the latest buzzwords!"
and
"Instead of highlighting the security threat of quantum technology and recommending funding for a scientifically justified response, the Manifesto makes the thoroughly deceptive claim that quantum technology improves security."
If critique is voiced (and this is absolutely legitimate), it should at least be based on a basic understanding of the underlying funding mechanisms, which I think is not the case in this article.
Everyone is aware of the fact that we don't yet have a full understanding of quantum algorithms and the computational power of quantum computers, what's clear though is that classical computers have certain limitations in various domains that can be overcome by quantum computers. What everyone agrees on is that quantum computers will not replace classical computers but will supplement them in certain niches.
Not sure if this answers all points, hope it clarifies a bit the motivations behind quantum computing though.
Why do you think that is the case?
I just really don't like this way of arguing, and I think it does a large injustice to most of the people involved, many of which are excellent scientists that have put lots of work into their winning proposal. Claiming that they are driven by greed or are selling "snake oil" is very unfair and also a bit ridiculous: The funding process was very transparent and open to debate, and there would surely have been a way for the author to voice his critique through an official channel, especially if he is a faculty member of a European University. To me it seems that he's just unhappy that the funding didn't go to his department, and instead of interacting with people in a constructive way (or better yet, get people from the crypto community together to write a proposal of their own) he just belittles the people involved in this project. This isn't scientific debating, it's just ranting.
The way I read it is: "Other people will research it, EU needs to research it as well" and that's the security benefit (not being behind on what could be a core technology with security and other implications).
"Semantic Web" did much better by having plenty of millions euros projects funded in FP6/7 and H2020 with absolutely no outcome.
European Semantic Web: http://eswc-conferences.org/ "Various automated services, based on reasoning with metadata and ontologies, will help the users to achieve their goals by accessing and processing information in machine-understandable form."
Will we see a surge in quantum_____.com domain regstrations?
How about a .quantum TLD?
