You can buy a portable [Chinese] quantum computer for under $9K

How exactly are they entangling the 2 qubits at room temperature? And how are they doing quantum error correcting? If I were to guess, I think they are lazily slapping on "quantum computing" to some system where QM is used to describe the properties of the system.

This is the page of the manufacturer:

As they wrote: "This product contains a powerful permanent magnet . The distance for 5 Gauss (0.5 mT) is 50 cm from this product. Keep a distance of at least 50 cm from cardiac pacemakers and other implanted electronic devices. Also, keep away from other electronic devices and magnetic media (credit cards, etc.)"

Is this avtually legitimate? I know 2 or 3 bits is nothing (qubits are the same in importance, right?) but this implies the ability to manufacture at scale and network them. For a few million, you could make a cluster able to break a lot of security.

Or how do I misunderstand?

> Triangulum ... 330W power draw ... weighing 40kg ... 3-qubit

Order one quantum-field store and load achieved? Just imagine buying that with a Cs-133 backup clock and an os that never reboot.
