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...

New paper dance!
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.

Our members have given a clear message, cuts this way is not the way forward. They want a more democratic governance of their university, reasonable workloads, and most importantly, to stop this devastating approach to HE as a business.

So your grand plan is to mock people (including your own supporters) for having to pay more for food? You aren’t just some rando on here, tell us what you are going to do about it and then go do it.

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”

One might think that Nazi crimes and palaeontology never overlapped, and yet... Have you ever wondered what happened to tens of palaeontologists & geologists in the Nazi-occupied Poland? How academics helped to bring down the fascist regime. And a curious story of Schindler-equivalent in geology. 🧵

We waste hundreds of billions a year on health care administrative expenses that make insurance CEOs and wealthy stockholders incredibly rich while 85 million Americans go uninsured or underinsured.

Health care is a human right.

We need Medicare for All.

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)

I’ve gotten a paper published in Quantum doi.org/10.22331/q-2... it always seemed like a neat journal and I’m glad I finally went for it, the review process was nice and we got some really good feedback which improved the work (co-authored with Jesse Berwald and Raouf Dridi)

I feel sorry for everyone I know back home in the US, but I’m REALLY glad I immigrated to the U.K. it isn’t perfect by any means, but it is a much better place to be 20th my family (it is difficult to describe to someone without US experience how bad/weird US politics and media are)

I wish that places like the UK and Canada would stop trying to shove profit models into healthcare; the US system is really bad, actually!
