  • its not useful for communication if you need to know that the other placed tried to communicate before measuring.

    But I don’t think you do. The classic slower-than-light communication here is just to verify the results. Once this system is operational, then by measuring the remote particles, you know exactly what information was sent.

    This of course assumes very good transmission fidelity (or error correction), and that the local sending side has some way to control the state their particle wavefunctions collapse into (otherwise they’re just sending random noise).




  • I’m no expert but I think this is how it works. We’ll call the particle pairs A, B, C, etc.

    So when the researchers measure Local particle A (LA for short), the nature of entanglement means that Remote particle A (RA) must collapse into a specific known state. So they measure RA after that happens. The same is true for pairs LB and RB, LC and RC, and so on. Then they check statistically if the remote particles are all in the predicted states (should be 100% if this works flawlessly).

    With enough repetition they can have very high confidence in the results. Of course those results must be communicated over traditional (non-entangled) channels that we already trust for reliability.

  • Ok serious comment: That’s a damn good review. And a surprisingly good quality device that’s a little ahead of its time.

    I’m impressed that you reached out to devs, contrasted with other handhelds, and tried so many different games. That’s almost everything I’d want to know.

    What kind of battery life does it get with various games? Sorry if I missed that. I expect ARM is a lot less power hungry than x86.
