Nonreciprocal Control of Spatiotemporal Floquet Dynamics in Levitated Optomechanical Arrays
Guangyu Zhang, Qihao Guo, Zhang-qi Yin
Periodically driven photonic and optomechanical systems provide a versatile setting for realizing collective Floquet dynamics, yet the relation between temporal locking and continu…
Programmable Superradiance in an Interacting Qubit Array
Botao Du, Qihao Guo, Ruichao Ma
When multiple quantum emitters couple to a common electromagnetic environment, interference in their collective radiative dynamics gives rise to superradiance and subradiance. In r…
Entangling Superconducting Qubits via Energy-Selective Local Reservoirs
Qihao Guo, Botao Du, Ruichao Ma
Engineered dissipation provides a powerful route to controlling and stabilizing quantum states in open systems. Superconducting circuits are particularly suited to this approach du…
