Cosmic Lockdown: When Decoherence Saves the Universe from Tunneling
Robson Christie, Jaewoo Joo, Greg Kaplanek +2
We investigate how quantum decoherence influences the tunneling dynamics of quantum fields in cosmological spacetimes. Specifically, we study a scalar field in an asymmetric double…

Quantum Simulation of Dynamical Transition Rates in Open Quantum Systems
Robson Christie, Kyunghyun Baek, Jeongho Bang +1
Estimating transition rates in open quantum systems is hampered by computing-resource demands that grow rapidly with system size. We present a quantum-simulation framework that ena…

Relativistic Quantum Simulation under Periodic and Dirichlet Boundary Conditions: A First-Quantised Framework for Near-Term Devices
Jaewoo Joo, Timothy P. Spiller, Kyunghyun Baek +1
We present a new recipe for relativistic quantum simulation using the first quantisation approach, under periodic (PBC) and Dirichlet (DBC) boundary conditions. The wavefunction is…
