Can a quantum circuit detect the Unruh effect?
Pravin Kumar Dahal, Timothy C. Ralph, William J. Munro +2
The Unruh effect predicts that an accelerating observer perceives the Minkowski vacuum as a thermal bath, yet direct detection remains experimentally inaccessible. Its timelike cou…
Powering Quantum Computation with Quantum Batteries
Yaniv Kurman, Kieran Hymas, Arkady Fedorov +2
Executing quantum logic in cryogenic quantum computers requires a continuous energy supply from room-temperature control electronics. This dependence on external energy sources cre…
Microwave Circulation in an Extended Josephson Junction Ring
Dat Thanh Le, Arkady Fedorov, Thomas M. Stace
Circulators are nonreciprocal devices that enable directional signal routing. Nonreciprocity, which requires time-reversal symmetry breaking, can be produced in waveguides in which…
Open-Source Highly Parallel Electromagnetic Simulations for Superconducting Circuits
David Sommers, Zach Degnan, Divita Gautam +4
Electromagnetic simulations form an indispensable part of the design and optimization process for superconducting quantum devices. Although several commercial platforms exist, open…
Experimental realization of qubit-state-controlled directional edge states in waveguide QED
Prasanna Pakkiam, N. Pradeep Kumar, Chun-Ching Chiu +3
We experimentally realise the theoretical proposal for in-situ tunable photonic edge states emerging from qubits coupled to a waveguide with a photonic bandgap. These edge states a…
