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…
Quantum Simulation and Optimization in Hot Quantum Networks
Martin J. A. Schuetz, Benoît Vermersch, Gerhard Kirchmair +4
We propose and analyze a setup based on (solid-state) qubits coupled to a common multi-mode transmission line, which allows for coherent spin-spin interactions over macroscopic on-…
Probing scrambling using statistical correlations between randomized measurements
Benoît Vermersch, Andreas Elben, Lukas M. Sieberer +2
We propose and analyze a protocol to study quantum information scrambling using statistical correlations between measurements, which are performed after evolving a quantum system f…
Probing entanglement entropy via randomized measurements
Tiff Brydges, Andreas Elben, Petar Jurcevic +6
Entanglement is the key feature of many-body quantum systems, and the development of new tools to probe it in the laboratory is an outstanding challenge. Measuring the entropy of d…
Unitary -designs via random quenches in atomic Hubbard and Spin models: Application to the measurement of Rényi entropies
B. Vermersch, A. Elben, M. Dalmonte +2
We present a general framework for the generation of random unitaries based on random quenches in atomic Hubbard and spin models, forming approximate unitary -designs, and their…
'Free-Space' Photonic Quantum Link and Chiral Quantum Optics
A. Grankin, P. O. Guimond, D. V. Vasilyev +2
We present the design of a chiral photonic quantum link, where distant atoms interact by exchanging photons propagating in a single direction in free-space. This is achieved by cou…
