- Guys, we need to stop this nonsense. Yes, some people go overboard on hype, but the anti-hype backlash is equally as wrong. A thread born out of frustration on misconceptions about quantum industry👇(1/n) (it's gotten so bad I've been driven to emojis!) thenextweb.com/news/oxford-sc…
- What a month for quantum error correction! First the Google result (full error correction with surface code), then MS/Quantinuum (color code computation demo), then AWS (cat qubits + repetition, suppression with scaling), now Yale (GKP beyond breakeven). arxiv.org/abs/2409.15065
- As a physicist, you realise pretty quickly that you're unlikely to win a Nobel Prize, but I've always secretly hoped that someone I've worked with would. Today they did. Enormous congratulations to Anton Zeilinger. I hope everyone at @iqoqivienna and @univienna are partying hard.
- I was asked recently to give predictions for QC in 2023. Here's what I said: 1. Death of NISQ 2. Further progress on fault-tolerance 3. Trouble for PQC 4. Clearer understanding of quantum advantage Four days into the year, and #4 seems to be coming true:
- How strongly do I believe quantum computing has a bright future? Strongly enough that I’ve just resigned from a tenured faculty position to be chief executive at @horizon_quantum.
- As Austria, France and the US add one to their Nobel laureate tally, I hope there are people celebrating in Belfast too. Bell may not still be with us, but his finger prints are all over this year’s prize and his theorem will live on forever.
- My twitter feed is full of negative takes on the @TIME quantum computing cover story, but I must admit that I was excited to see it and view it as something of a milestone in terms of QC entering the public consciousness. So here’s a thread in defence of quantum optimism. (1/n)
- Was a bit surprised to see this paper being cited in a bibliometric analysis of quantum machine learning. It doesn’t have many citations, mostly because it doesn’t exist.
- Exciting work from @GoogleQuantumAI showing error suppression beyond breakeven and scaling with distance. Massively outperforms last year's results. The pace of progress towards fault-tolerance is really picking up. Now do it with an asymptotically good code!🙃
- Physicists don’t quote other physicists to physicists. It’s the correctness of the argument that matters, not who first said it, but somehow both Hollywood and crackpots get this wrong. It’s a bit painful seeing it in 3 Body Problem.
- I thought I had a new joke about physics, but it’s been known in Russia since the 1970s.
- It's a big day for us today at Horizon, as we announce our latest funding round, led by @Sequoia_India.Today, we announce our seed financing increase to SGD 4.5 m (USD 3.23 m) thanks to a seed-plus round led by @Sequoia_India with participation from previous investors @SGInnovate, Abies Ventures, @DCVC, Qubit Protocol, Summer Capital and Posa CV. #QuantumComputing
