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…
Shell-shaped Bose-Einstein condensates: Dynamics, excitations, and thermodynamics
Brendan Rhyno, Kuei Sun, Jude Bedessem +3
Shell-shaped Bose-Einstein condensates (BECs) represent a paradigmatic instance of quantum fluids in hollow geometries exhibiting phenomena that bridge from ultracold atomic to ast…
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…
Mechanical cosmology: simulating scalar fluctuations in expanding Universes using synthetic mechanical lattices
Brendan Rhyno, Ivan Velkovsky, Peter Adshead +2
Inspired by recent advances in observational astrophysics and continued explorations in the field of analog gravity, we discuss the prospect of simulating models of cosmology withi…
