I've discovered that all popular quantum computing SDKs / compilers have serious bugs when it comes to handling angles -- floating point strikes again!
IBM's Qiskit, Google's Cirq, Rigetti's quilc, IQM's Qrisp, NVIDIA's CUDA-Q, Xanadu's PennyLane, qBraid's SDK, ...

Models are sycophantic, and when they do challenge faulty or incorrect inputs, they're ambiguous and ineffective.
In a new paper w/ multilingual co-authors, we find that people may view LM responses that push back, yet still end up believing false content is true.

More cake to celebrate Francis Halzen’s well-deserved Nobel Prize @NobelPrize ! 🎂 Proud to be part of UW–Madison Physics @UWMadPhysics, where extraordinary science continues to happen. Here’s to more discoveries—and more milestones worth celebrating—in the years ahead!
I used to Claude to build some security tool. It built the thing. Then at some point it realized it’s debugging a security tool and the guardrails kicked in 😂

IMO, any future experimental claims should come with the entire software stack. Otherwise, take them with a grain of salt and a shot of Guadalajara's heaviest offerings.

From the (excellent) WSJ obit of Margaret Hamilton: she left behind 2^0 daughters, 2^1 grandsons, and 2^2 great-grandchildren. Total boss behavior.

first tzap paper will (conditionally) appear at POPL (arxiv.org/abs/2605.13929)
My summer project has been to build the fastest + most scalable quantum-circuit optimizer.
It’s called tzap, scales to millions of gates in seconds (needed for fault tolerance) + outperforms superoptimizers that take hours.
