Exact fermionic dual of the Bose-Hubbard model
Lei Su, Ivar Martin, Aashish A. Clerk
Recent developments have established exact bosonization and fermionization with a symmetry as dualities through gauging. In this work, we apply fermionic gauging, wh…
Global Precision Bounds and Success-Probability Guarantees in Quantum Parameter Learning
Federico Belliardo, James W. Gardner, Liang Jiang +1
Quantum metrology offers the possibility of quantum enhancements of the precision of various sensing tasks. In this manuscript, we tackle two open problems in the theory of single-…
Efficient Simulation of Nonreciprocal Many-body Physics via Quantum Feedback
Kseniia Vodenkova, Andrew Pocklington, Fan Yang +3
We present a scheme to efficiently simulate nonreciprocal many-body spin models using a non-Markovian open system. Our scheme utilizes a single quantum emitter coupled to a wavegui…
Correlated Coherent Errors in Stabilizer Codes: A General Cumulant Framework and Interference-Based Error Suppression
Rohan N Rajmohan, Antoine Brillant, Peter Groszkowski +3
Coherent errors in stabilizer codes are often correlated across qubits and QEC cycles. Having a general analytical treatment of such noise would thus be extremely valuable. We deri…
Floquet Reservoir Engineering for Remote Logical Entanglement
Mingxing Yao, Aashish A. Clerk
Implementing controlled dissipative dynamics is a powerful approach for state preparation in a variety of contexts, including the preparation of remote entangled states. Here, we s…
Symmetry as a route to generalized bosonic Kitaev chains
Gideon Lee, Tony Jin, Aashish A. Clerk
The bosonic Kitaev chain (BKC) model is a deceptively simple looking quadratic pairing Hamiltonian. Despite being purely Hermitian, it exhibits a number of striking non-Hermitian t…
Exact metastability in a class of driven-dissipative quantum many-body systems
David D. Noachtar, Aashish A. Clerk
Metastability in many-body quantum systems and its associated exponentially-long timescales have been the subject of considerable recent interest. Here, we focus on a class of driv…
Exact steady states of interacting driven dissipative fermionic systems with hidden time-reversal symmetry
Andrew Lingenfelter, Aashish A. Clerk
We present exact solutions for the non-equilibrium steady states of a class of dissipative spinless fermionic systems with arbitrary Hamiltonian pairing terms, global charging ener…
Noise Correlations as a Resource in Pauli-Twirled Circuits
Antoine Brillant, Rohan N Rajmohan, Peter Groszkowski +3
Randomized compiling (RC) is an established tool to tailor arbitrary quantum noise channels into Pauli errors. The effect of both spatial and temporal noise correlations in randoml…
Insights into decohered critical states using an exact solution to matchgate circuits with Pauli noise
Andrew Pocklington, Aashish A. Clerk
The fate of non-trivial many-body states subject to decoherence is of both fundamental and practical interest. Here, we demonstrate a new analytic technique that allows for an exac…
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…
Asymptotic Scaling of Precision Limits in Continuous Gaussian Quantum Metrology
Kazuki Yokomizo, Aashish A. Clerk, Yuto Ashida
Continuous quantum metrology holds promise for realizing high-precision sensing by harnessing information progressively carried away by the radiation quanta emitted into the enviro…
