Channel Superposition Mitigates Photon Loss Errors in Quantum Illumination
Fei Li, Xiao-Wei Li, Oscar Dahlsten
In quantum illumination, the probe photon is entangled with an ancilla photon, and both are jointly measured at the end. The entanglement between the probe and ancilla photons enha…

Hybrid Real-Imaginary Time Evolution for Low-Depth Hamiltonian Simulation in Quantum Optimization
Fei Li, Xiao-Wei Li
Counterdiabatic (CD) driving is a powerful technique for accelerating adiabatic quantum computing. However, it becomes self-limiting in complex optimizations like the Sherrington-K…
