New preprint with @njohnston.ca: "Distinguishability of locally diagonal orthogonally invariant quantum states" Optimal measurements preserve LDOI structure, reducing optimization from n^4 to O(n^2) variables. For two-qubit cases: LOCC = SEP = PPT.

How do you ensure quantum benchmarking happens in the open? Unitary Foundation has released an update to the open-source Metriq platform for collaborative benchmarking of quantum computers. We describe the platform in a new paper, which came out today: scirate.com/arxiv/2603.0...
Metriq is introduced as an open-source platform that standardizes quantum computer benchmarking by integrating benchmark design, execution, data collection, and public reporting into a unified workflow.

All results are version-controlled in a public dataset and visible at metriq.info. The suite is designed to evolve. New benchmarks enter through community RFCs.

We built an open platform to run the same benchmarks across quantum hardware from IBM, Quantinuum, IQM, Rigetti, IonQ, and OriginQ, then compared them all.

New paper:
Uses quantum circuit "unoptimization" as a noise-scaling technique for the ZNE (zero-noise extrapolation) error mitigation strategy.

Layerwise Richardson extrapolation (LRE) is a quantum error mitigation (QEM) technique defined in (the recently published): journals.aps.org/pra/abstract...
LRE has been implemented in mitiq as a QEM method you can use today!
