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…
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…
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…
