Quantum information scrambling in a trapped-ion quantum simulator with tunable range interactions
Manoj K. Joshi, Andreas Elben, Benoît Vermersch +5
In ergodic many-body quantum systems, locally encoded quantum information becomes, in the course of time evolution, inaccessible to local measurements. This concept of "scrambling"…
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…
Statistical correlations between locally randomized measurements: a toolbox for probing entanglement in many-body quantum states
Andreas Elben, Benoît Vermersch, Christian F. Roos +1
We develop a general theoretical framework for measurement protocols employing statistical correlations of randomized measurements. We focus on locally randomized measurements impl…
Implementation of Chiral Quantum Optics with Rydberg and Trapped-ion Setups
Benoît Vermersch, Tomás Ramos, Philipp Hauke +1
We propose two setups for realizing a chiral quantum network, where two-level systems representing the nodes interact via directional emission into discrete waveguides, as introduc…
