An Improved Bound on Nonlinear Quantum Mechanics using a Cryogenic Radio Frequency Experiment
Oleksandr Melnychuk, Bianca Giaccone, Nicholas Bornman +9
There are strong arguments that quantum mechanics may be nonlinear in its dynamics. A discovery of nonlinearity would hint at a novel understanding of the interplay between gravity…

Phase-controlled improvement of photon lifetime in coupled superconducting cavities
Changqing Wang, Oleksandr S Melnychuk, Crispin Contreras-Martinez +9
High-quality cavities are crucial for various fundamental physical studies and applications. Here we find that by coupling two cavities directly or via a phase-tunable coupling cha…
