Precision Limits of Multiparameter Markovian-Noise Metrology
Anthony J. Brady, Yu-Xin Wang, Luis Pedro García-Pintos +1
Measuring stochastic signals ("noise metrology") constitutes a central task in quantum sensing and the characterization of open quantum systems. Here we establish ultimate precisio…

Entanglement and circuit complexity in finite-depth random linear optical networks
Laura Shou, Joseph T. Iosue, Yu-Xin Wang +2
We study the growth of entanglement and circuit complexity in random passive linear optical networks as a function of the circuit depth. For entanglement dynamics, we start with an…
