I’ve worked on topological quantum computation, one of Alexei Kitaev’s brilliant innovations, for around 15 years now. It’s hard to find a more beautiful physics problem, combining spectacular quantum phenomena (non-Abelian anyons) with the promise of transformative technological advances (inherently … Continue reading →
Assa Auerbach’s course was the most maddening course I’ve ever taken. I was a master’s student in the Perimeter Scholars International program at the Perimeter Institute for Theoretical Physics. Perimeter trotted in world experts to lecture about modern physics. Many … Continue reading →
Last August, Toronto’s Centre for Quantum Information and Quantum Control (CQIQC) gave me 35 minutes to make fun of John Preskill in public. CQIQC was hosting its biannual conference, also called CQIQC, in Toronto. The conference features the awarding of … Continue reading →
You might have heard of the conundrum “What do you give the man who has everything?” I discovered a variation on it last October: how do you celebrate the man who studied (nearly) everything? Physicist Edwin Thompson Jaynes impacted disciplines from quantum information theory to biomedical imaging. I almost wrote “theoretical physicist,” instead of “physicist,” […]
On December 11, I gave a keynote address at the Q2B 2024 Conference in Silicon Valley. This is a transcript of my remarks. The slides I presented are here. NISQ and beyond I’m honored to be back at Q2B for … Continue reading →

Within 1-5 years, our daily transportation will be upended, and cities will be reshaped.
We’ve known about far-UVC’s promise for a decade. Why isn't it everywhere?
Larger models can pull off greater feats, but the accessibility and efficiency of smaller models make them attractive tools. The post Why Do Researchers Care About Small Language Models? first appeared on Quanta Magazine
For my entire career as a neurologist, spanning three decades, I have been hearing about various kinds of stem cell therapy for Parkinson’s Disease (PD). Now a Phase I clinical trial is under way studying the latest stem cell technology, autologous induced pluripotent stem cells, for this purpose. This history of cell therapy for PD […] The post Stem Cells for Parkinson’s Disease first appeared on NeuroLogica Blog.
In math and computer science, researchers have long understood that some questions are fundamentally unanswerable. Now physicists are exploring how even ordinary physical systems put hard limits on what we can predict, even in principle. The post ‘Next-Level’ Chaos Traces the True Limit of Predictability first appeared on Quanta Magazine
