Pauli Twirling + Probabilistic Cancellation Boost NISQ Fidelity
Back in 2023, I gave a series of lectures at the Boulder Summer School on then-recent techniques we developed for error mitigation in NISQ devices, specifically how to combine Pauli twirling with probabilistic error cancellation to improve fidelity in noisy quantum circuits.
Post‑Quantum Upgrade: Blockchains’ Biggest Technical Overhaul Yet

Quantum Threat to Bitcoin Looms, Timeline Uncertain
When would quantum computers be able to break Bitcoin? 🤔 Alex Pruden says “it's hard to project” but warns that things are moving fast 👇 #quantumcomputing #cryptography #blockchain
Quantum Fear Should Spur Bitcoin Fixes, Not Complacency
Bitcoin and the Quantum Threat: Think about the Year 2000 bug. Remember Y2K? It was a great example of the positive effects of over-worrying. I'm old enough to remember how everyone was talking about how the world is going to end...
Shadow Tomography of GKP Logical Subsystems via Twirled Measurements
Chasing shadows with Gottesman-Kitaev-Preskill codes https://t.co/n2Ez7A6Ehz We explore a research question at the intersection of #quantumerrorcorrection and #quantumlearningtheory. Concretely, we consider the task of performing shadow tomography of a logical subsystem defined via the Gottesman-Kitaev-Preskill (#GKP) error correcting code. Our protocol does...
Quantum Error Correction Defies Classical Intuition, Misconceptions Abound
One thing I didn’t fully appreciate early on while learning quantum error correction is just how far it can deviate from classical intuition. Along the way, I’ve run into some common misconceptions (which I still see often):

Deep Dialogue on Quantum Futures and Science Outreach
It has been a great pleasure—and both fun and insightful—to speak with Thomas Ramge about the future of quantum technologies, broader aspects of science and technology, and what makes science so exciting in the first place. I especially appreciate the...
