Quantum error mitigation by hierarchy-informed sampling: chiral dynamics in the Schwinger model
Theo Saporiti, Oleg Kaikov, Vasily Sazonov +1
Quantum simulations on current NISQ hardware are limited by its noisy nature, making efficient quantum error mitigation methods highly demanded. In this paper we introduce a novel…
BBGKY hierarchy for quantum error mitigation
Theo Saporiti, Oleg Kaikov, Vasily Sazonov +1
Mitigation of quantum errors is critical for current NISQ devices. In the present work, we address this task by treating the execution of quantum algorithms as the time evolution o…
Quantum Error Mitigation by Global Randomized Error Cancellation for Adiabatic Evolution in the Schwinger Model
Oleg Kaikov, Theo Saporiti, Vasily Sazonov +1
We extend the global randomized error cancellation (GREC) method for quantum error mitigation (QEM) in an application to adiabatic evolution of states on a noisy quantum device. We…
Thermalization in a model of enhanced memory capacity
Oleg Kaikov
We study thermalization within a quantum system with an enhanced capacity to store information. This system has been recently introduced to provide a prototype model of how a black…
Phase Diagram of the Schwinger Model by Adiabatic Preparation of States on a Quantum Simulator
Oleg Kaikov, Theo Saporiti, Vasily Sazonov +1
We argue the feasibility to study the phase structure of a quantum physical system on quantum devices via adiabatic preparation of states. We introduce a novel method and successfu…
