Ask HN: Quantum dot lattices as a classical-quantum middle ground?
The basic thought is pretty simple: instead of trying to maintain perfect quantum states (which is insanely hard), what if we design systems that deliberately operate in that messy middle area? Kind of like how our brains aren't digital or quantum, but still do interesting computation.
I'm particularly fascinated by how quantum dots could be arranged in lattices where they exhibit some quantum behaviors (tunneling, limited coherence) while still behaving predictably enough for practical use. The killer feature would be operating at normal-ish temperatures without needing the extreme cooling infrastructure.
Some specifics I've been thinking about: - QD lattices with ~5-10nm dots in specific arrangements - Room temp operation (or at least liquid nitrogen vs millikelvin) - Using "observer dots" that let you measure states without collapsing the whole system
I've written up a more detailed paper on this, but frankly, I'm just a curious person without academic credentials in this space. I'd love to hear if:
1. This is obviously flawed for reasons I'm missing 2. Similar work is already happening somewhere (pointers appreciated!) 3. Anyone with lab access might find this intriguing enough to test some aspects
Has anyone seen anything in this direction? Am I reinventing a wheel or missing something fundamental? Thanks!
