Some statistical features of Haar unitaries can be well approximated in log depth, exponentially faster than previously thought. We give evidence that this is a 'truly quantum' effect by deriving linear lower bounds for orthogonal, Clifford, symplectic, matchgate groups scirate.com/arxiv/2506.2...

Great conference at Genoa, Italy about "Time in Quantum Theory" (TIQT)😀 I'll use the ocasion to share my related seminar doi.org/10.52843/cas... on our recent paper "Path Integrals from spacetime quantum actions" (doi.org/10.1016/j.ao...). The topic? Unifying "Quantum time" and Feynman's approach

🚨Excited to share our new paper "Characterizing quantum resourcefulness via group-Fourier decompositions" from last year's LANL Quantum Computing summer School📘 arxiv.org/abs/2506.19696 !

How fast can quantum circuits compile group designs?Recent work arxiv.org/abs/2407.07754 showed that designs over the n-qubit unitary group can be compiled in logarithmic-in-n depth. Can we similarly build short-depth designs over other groups? In our new paper arxiv.org/abs/2506.16005 we answer no.
