back to article Boffins demo on-chip entanglement at macro scale

Quantum computing watchers are familiar with the idea of entanglement – the “spooky action at a distance” that gives rise to quantum teleportation. Now, a team led by the University of Queensland is claiming a different kind of first: quantum teleportation between two spots on a single chip. Not only that: but unlike schemes …

    I didn't understand a word of that

    Then again, I'm 60 years old and (so others keep telling me) past it. What's your excuse?

      Don't worry too much, I have a physics degree (from many years ago now) and I don't really "get it" either.

      I blame Thatcher / Blair / Immigrants / Bi-Weekly Bin Collection, oh hold on CALPOL!

    They appear to have created a 0.2mm wide "virtual" atom

    Which is a hell of a lot easier to handle.

    And note that if you can build one of these chips you can build more.

    If I'm reading this right using microwaves instead o light means you can take many fewer measurements to establish the quantum state than you need with light. This gives the data rate of 10Kbps, but I don't know if that's good or not.

    Historically digital logic took off when a)Standardized chips became available (the TTL 7400 series, but there were predecessors) and mathematical tools like Karnough maps and the Quinn McKlusky algorith for logic minimization.

    I think this field still lacks the latter but this might be the start of the former.

    Thumbs up for the work.

    Ahhhh....Karnaugh.....

    The days of logic minimisation, 'don't care' states and little rings around clusters of ones and zero's are long gone....

    Does this mean

    we'll finally get the 'IF' and 'BUT' gates I could have done with back in the seventies?

      Not probable, but there is a chance for Microwave Assisted Yield Bracketed Excitator gates.
