Quantum Technology News – Issue #9

The biggest news of the week is the long anticipated Google quantum computing announcement. The announcement states that the D-Wave machine is more than 10^8 times faster than simulated annealing running on a single core.

Independent analyses by Dr. Scott Aaronson show that while the results are showing that D-Wave is becoming more mature and probably has quantum effects, the technology suffers the drawbacks of just being built on old quantum computing techniques that we know are not the most optimal anymore. Additionally, Selby’s algorithm (a classical algorithm on a classical computer) still outperforms D-Wave.

In the cryptography community, even though the D-Wave computer cannot break modern cryptography, the fact that the NSA is preparing to move to quantum resistant algorithms shows that there is concern over either: quantum computing research acceleration, or problems with existing ECC algorithms (or both?).

Australian continues to fund quantum computing research and announce breakthroughs weekly, this time on a quantum computer code that will allow for the beginning of a full-stack solution to controlling and programming a quantum computer, built on top of the breakthrough last month, where UNSW showed the first logic gate in a silicon chip.
