Dynamical quantum phase transitions of the Schwinger model: real-time dynamics on IBM Quantum

D Pomarico, L Cosmai, P Facchi, C Lupo, S Pascazio… - Entropy, 2023 - mdpi.com
Simulating the real-time dynamics of gauge theories represents a paradigmatic use case to
test the hardware capabilities of a quantum computer, since it can involve non-trivial input …

Dynamical quantum phase transitions following a noisy quench

R Jafari, A Langari, S Eggert, H Johannesson - Physical Review B, 2024 - APS
We study how time-dependent energy fluctuations impact the dynamical quantum phase
transitions (DQPTs) following a noisy ramped quench of the transverse magnetic field in a …

Noise Removal in IBM Real Time Quantum Computer with Deviation Quantum Algorithm in Comparison with Variational Quantum Eigensolver Algorithm

PV Ramana, TS Balakrishnan - 2024 Second International …, 2024 - ieeexplore.ieee.org
The fundamental purpose of this study is to reduce the amount of noise that is produced by
IBM quantum computers that are running in real time. This will be accomplished by adopting …
