Almost exactly one year ago, I found a way to make quantum attacks on elliptic curve cryptosystems ten times cheaper. Specifically, I found a better way to perform elliptic curve point addition on a quantum computer. I wanted to publish th...

In this post: why I expect the maximum achievable qubit quality to increase drastically in the next few years.

In 2014, the John Martinis group at UCSB performed an experiment where they stored a classical bit using their quantum computer. They protected the bit with a 9 qubit<...
