Hardware-Efficient Continuous-Variable Quantum Computation: Finite- Non-Gaussian Gates in a Floquet-Engineered Cavity-BEC
Soi-Chan Lei
Continuous-variable (CV) quantum computation in bosonic modes offers a hardware-efficient route toward fault tolerance, yet synthesizing deterministic, macroscopic non-Gaussian gat…

Microsecond-Programmable Synthetic Quantum Matter: Circumventing the Adiabatic Bottleneck for Heisenberg-Limited Metrology
Soi-Chan Lei
Generating macroscopic quantum entanglement is central to quantum metrology. While traversing a quantum critical point yields Heisenberg-limited precision, adiabatic schemes are re…

A Unified Josephson Dynamics Perspective for Single-Cavity BECs: From Self-Trapping to Dynamical Phase Transitions
Soi-Chan Lei
We investigate a two-component Bose-Einstein condensate (BEC) strongly coupled to a single optical cavity, effectively described by a mean-field Dicke model supplemented with inter…
