Quantum speedups for stochastic optimization
Aaron Sidford, Chenyi Zhang
We consider the problem of minimizing a continuous function given quantum access to a stochastic gradient oracle. We provide two new methods for the special case of minimizing a Li…

Emission spectral non-Markovianity in qubit-cavity systems in the ultrastrong coupling regime
Chenyi Zhang, Minghong Yu, Yiying Yan +3
We study the emission spectra of dissipative Rabi and Jaynes-Cummings models in the non-Markovian and ultrastrong coupling regimes. We have derived a polaron-transformed Nakajima-Z…
