Observable Estimation in the Absence of Classical Verification
Samantha V. Barron, Bradley Mitchell, Vinay Tripathi +45
The paper proposes a framework to independently validate observable estimates from quantum computers when classical benchmarks are unavailable, using experiments such as the operat…
Accelerating qubit reset through the Mpemba effect
Théo Lejeune, Miha PapiÄ, John Goold +3
Passive qubit reset is a key primitive for quantum information processing, whereby qubits are initialized by allowing them to relax to their ground state through natural dissipatio…
A derivation of the late-time volume law for local operator entanglement
Guilherme Ilário Correr, John Goold, Marco Cattaneo
Local Operator Entanglement (LOE) has emerged an indicator of quantum chaos in many-body systems. Numerical studies have shown that, in chaotic systems, LOE grows linearly in time…
Thermodynamic universality across dissipative quantum phase transitions
Laetitia P. Bettmann, Artur M. Lacerda, Mark T. Mitchison +1
We study finite-time driving across second-order dissipative quantum phase transitions described by Lindblad dynamics. We show that the nonadiabatic entropy production, which quant…
A Random Matrix Theory of Pauli Tomography
Nathan Keenan, John Goold, Alex Nico-Katz
Quantum state tomography (QST), the process of reconstructing some unknown quantum state from repeated measurements on copies of said state, is a foundationally important…
Information geometry of transitions between quantum nonequilibrium steady states
Artur M. Lacerda, Laetitia P. Bettmann, John Goold
In a transition between nonequilibrium steady states, the entropic cost associated with the maintenance of steady-state currents can be distinguished from that arising from the tra…
