Observing quantum many-body dynamics in emergent curved spacetime using programmable quantum processors
Brendan Rhyno, Bastien Lapierre, Smitha Vishveshwara +2
We digitally simulate quantum many-body dynamics in emergent curved backgrounds using 80 superconducting qubits on IBM Heron processors. By engineering spatially varying couplings…

Quantum critical dynamics and emergent universality in decoherent digital quantum processors
Brendan Rhyno, Swarnadeep Majumder, Smitha Vishveshwara +1
Understanding how noise influences nonequilibrium quantum critical dynamics is essential for both fundamental physics and the development of practical quantum technologies. While t…

Matrix-product-state-assisted variational Gibbs-state preparation
Rui-Hao Li, Semeon Valgushev, Khadijeh Najafi
Evaluating the von Neumann entropy is a central challenge in variational Gibbs-state preparation. We introduce and benchmark matrix-product-state (MPS) assistance for classically e…
