Improving success probability in Lechner-Hauke-Zoller parity embedding by computing with quantum walks
Lechner-Hauke-Zoller (LHZ) parity embedding is one of the front-running methods for implementing difficult-to-engineer long-range interactions in quantum optimization problems. Continuous-time quantum...

Excellent work by @jbennett107.bsky.social at @iqoqi.bsky.social with @quantumchancellor.bsky.social and Wolfgang Lechner, showing that the LHZ encoding works with quantum walks, i.e., diabatic driving.

People who haven’t spent much time in the LA area might imagine the surrounding forests are like the ones we have in England, but it’s actually incredibly dense brush growing on very steep slopes with cliffs in places, there isn’t a good way to “just rake up the leaves”
Musk spreading lies again with comparisons out of context.
Fuel density and moisture is different in Texas. There is much more dry fuel present in California forests. There is also more effective fuel management because of the different topography in Texas.

I left the US for the UK over a decade ago and over the years I have had some very attractive offers to go back, healthcare is a big part of the reason why (of course I recognise that leaving isn’t a viable option for most people)
