Quantum Computing has appeared frequently in the news this year. And deservedly so, because it is making steady progress. On Feb.17, I posted an entry titled “Experimental Quantum Computing, State of the Art”, where I discussed an excellent review article of QC hardware written by Franco Nori and his team. Now, 8 months later, that review article is already seriously out of date.
I just counted how many stories NextBigFuture has had since the beginning of the year under the subject of “quantum computer”:
34 stories from Jan 1 to Oct 1. All in all, a pretty exciting year if you ask me. Many of those stories are not earth-shaking events, but some are. For instance, measuring the spin state of a single electron (the electron belongs to a donor Phosphorus atom implanted in a Silicon crystal). Wow!
The public might be understandably confused. What hardware approach will win the race for a scalable quantum computer. Is it going to be ???
- an ion trap quantum computer (NIST),
- or a superconductive device that implements an adiabatic QC à la D-Wave,
- or a superconductive device that implements the gate model (Yale and UCSB)
- or an array of donors implanted in Silicon by the Australians and Finns,
- or NV color centers in diamond,
- or a photonic QC by the Brits,
- or Rydberg atoms
- or an anyonic QC
I probably left out a few.
Makes me glad I specialize in writing quantum computing software, which is somewhat platform independent, so I don’t have to guess which of all these wonderful approaches will win out.
