Weak-Field Expansion: A Time-Closed Solution of Quantum Three-Wave Mixing
Hanzhong Zhang, Avi Pe'er
We present a systematic derivation of the Heisenberg evolution of a trilinear bosonic Hamiltonian system in presence of a strong drive beyond the standard approximation of a classi…

Quantum matched filtering: breaking time-energy separability by 12 orders of magnitude
Nir Nechushtan, Hanzhong Zhang, Yosef London +4
Detection of signals buried in noise is the major challenge for sensing. Classically, the optimal detector is a matched filter, whose sensitivity meets the classical limit of corre…
