Detecting quantum noise of a solid-state spin ensemble with dispersive measurement
Mikhail Mamaev, Jayameenakshi Venkatraman, Martin Koppenhöfer +2
We theoretically explore protocols for measuring the spin polarization of an ensemble of solid-state spins, with precision at or below the standard quantum limit. Such measurements…
Tunable quantum Mpemba effect in long-range interacting systems
Andrew Hallam, Matthew Yusuf, Aashish A. Clerk +2
Symmetry plays a fundamental role in many-body systems, both in and out of equilibrium. The quantum Mpemba effect (QME) - a phenomenon where systems initially farther from equilibr…
Timescales, Squeezing and Heisenberg Scalings in Many-Body Continuous Sensing
Gideon Lee, Ron Belyansky, Liang Jiang +1
The continuous monitoring of driven-dissipative systems offers new avenues for quantum advantage in metrology. This approach mixes temporal and spatial correlations in a manner dis…
Quantum Mpemba effect without global symmetries
Tanmay Bhore, Lei Su, Ivar Martin +2
The Mpemba effect, where a system initially farther from equilibrium relaxes faster than one closer to equilibrium, has been extensively studied in classical systems and recently e…
Efficient simulation of non-trivial dissipative spin chains via stochastic unraveling
Andrew Pocklington, Aashish A. Clerk
We present a new technique for efficiently simulating (in polynomial time) a class of one-dimensional (1D) dissipative spin chains that, when mapped to fermions, have quadratic Ham…
Randomized benchmarking with non-Markovian noise and realistic finite-time gates
Antoine Brillant, Peter Groszkowski, Alireza Seif +2
We analyze the impact of non-Markovian classical noise on single-qubit randomized benchmarking experiments, in a manner that explicitly models the realization of each gate via real…
