The 2025 Nobel prize in physics has been awarded for pioneering the use of Josephson junctions in superconducting circuits to demonstrate and control fundamental quantum phenomena. For example collective quantum tunnelling effects for large numbers (billions) of particles

BREAKING NEWS The Royal Swedish Academy of Sciences has decided to award the 2025 #NobelPrize in Physics to John Clarke, Michel H. Devoret and John M. Martinis “for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.”

In our last post, we shared the preliminary results of 1-hour bit-flip lifetime for our cats! 🐱 To put that in perspective, that’s millions of times longer than the previous lifetimes achieved on superconducting chips. But why do long-lived qubits matter for quantum? As…

Caltech physicists have created the largest qubit array ever assembled: 6,100 neutral-atom qubits trapped in a grid by lasers. Previous arrays of this kind contained only hundreds of qubits. caltech.edu/about/news/cal…

💭 Reasoning in mathematics and reasoning in physics have very different textures. Mathematics is held together by short-range forces that bind each step in a deduction directly to the preceding steps, whereas physics is held together by the much longer-range forces of analogy…


New video! 🎥 Do wave functions really have to vanish at infinity? ⚛️✉️ We explore a fascinating example: a wave function that is continuous, differentiable, and normalizable, yet unbounded at infinity. Watch here 👉 youtu.be/t8x4Kw11c80
