Cross-Platform Verification of Intermediate Scale Quantum Devices
Andreas Elben, Benoît Vermersch, Rick van Bijnen +7
We describe a protocol for cross-platform verification of quantum simulators and quantum computers. We show how to measure directly the overlap an…

Many-body topological invariants from randomized measurements
Andreas Elben, Jinlong Yu, Guanyu Zhu +4
The classification of symmetry-protected topological (SPT) phases in one dimension has been recently achieved, and had a fundamental impact in our understanding of quantum phases i…

Subradiant Bell states in distant atomic arrays
P. -O. Guimond, A. Grankin, D. V. Vasilyev +2
We study collective `free-space' radiation properties of two distant single-layer arrays of quantum emitters as two-level atoms. We show that this system can support a long-lived B…
