Distributed Quantum Metrology and the Entangling Power of Linear Networks
Wenchao Ge, Kurt Jacobs, Zachary Eldredge +2
We derive a bound on the ability of a linear optical network to estimate a linear combination of independent phase shifts by using an arbitrary non-classical but unentangled input…
A solvable family of driven-dissipative many-body systems
Michael Foss-Feig, Jeremy T. Young, Victor V. Albert +2
Exactly solvable models have played an important role in establishing the sophisticated modern understanding of equilibrium many-body physics. And conversely, the relative scarcity…
Dynamical phase transitions in sampling complexity
Abhinav Deshpande, Bill Fefferman, Minh C. Tran +2
We make the case for studying the complexity of approximately simulating (sampling) quantum systems for reasons beyond that of quantum computational supremacy, such as diagnosing p…
Entanglement area laws for long-range interacting systems
Zhe-Xuan Gong, Michael Foss-Feig, Fernando G. S. L. Brandão +1
We prove that the entanglement entropy of any state evolved under an arbitrary long-range-interacting D-dimensional lattice spin Hamiltonian cannot change faster than a rat…
Exact sampling hardness of Ising spin models
Bill Fefferman, Michael Foss-Feig, Alexey V. Gorshkov
We study the complexity of classically sampling from the output distribution of an Ising spin model, which can be implemented naturally in a variety of atomic, molecular, and optic…
