21 = 3 * 7

…with high probability. That joke was recycled, and in recent work, Bristol experimentalists have found a way to recycle photonic qubits to perform Shor’s algorithm using only $latex lceil log Nrceil + 1$ qubits. (Ok, so actually is was Kitaev … Continue reading

Greg Kuperberg: a paladin fighting against the ogres of hype

Nothing much to add here, but Greg Kuperberg has an excellent article at Slate which clarifies the power and limitations of quantum computers. The article is brief, accessible, and highly accurate. The next time a science journalist contacts you for … Continue reading

Throwing cold water on the Quantum Internet

There has been a lot of loose talk lately about a coming “Quantum Internet”. I was asked about it recently by a journalist and gave him this curmudgeonly answer, hoping to redirect some of the naive enthusiasm: …First let me … Continue reading

Lucky 13 paper dance!

Having recently rediscovered arxiv.org/submit, I thought I’d mention a few papers to come out of team UW. Two particularly exciting single-author papers are from students here. Kamil Michnicki has developed a 3-d stabilizer code on $latex n$ qubits with an … Continue reading

Threading the needle of mathematical consistency

The latest round of the debate between Aram and Gil Kalai is now up over at Goedel’s Lost Letter. I realize that I’m preaching to the choir at this venue, but I thought I would highlight Aram’s response. He nicely … Continue reading
