When atoms cross a region they should never be able to enter, how long do they spend inside it? Proud of our team at @uoftphysics and @CIFAR_News for answering this question: physics.utoronto.ca/~aephraim/tunn… (Full article at nature.com/articles/s4158…) #quantum #tunneling #QMFoundations

Finally read this fascinating article by Amanda Gefter -- kudos on an epic investigation and a gripping story! Sad but also inspiring. Great move making much of his archive publicly available. nautil.us/finding-peter-… @NautilusMag

Fearing yet more war; hoping for peace. May war-mongering leaders be removed, and innocents everywhere be safe. What else is worth saying?

Disgusting Weaponizing the justice department, and research funding, against what the US has left of intellectual institutions. Against one of the real good guys, at that. His crime? Not dismantling efforts in support of equity vigorously enough. nytimes.com/2025/06/27/us/…

RIP Ray Laflamme, gone too soon. Ray was a stellar scientist, the founding director of ⁦@QuantumIQC⁩ and ⁦@CIFAR_News's⁩ Quantum Information program, but more importantly a warm & generous human who built community and helped many. May his memory be a blessing.

Krister Shalm in the news again, with a new paper on the Colorado Random Number beacon. Well, we always did say that getting a paper into Nature was a roll of the dice... Always exciting to see our group members go on to lead such successful efforts! nature.com/articles/s4158…

Sad news. A great scientist & author, of course, but also a kind man and thoughtful teacher. He will be missed. optica.org/about/newsroom…

I like to hope we're already doing this in Physics (at least in most groups..), but a discussion around a more systematic approach like this would not be out of place. #AcademicTwitter #PhDEducation
