Dephasing in coherent communication with weak signal states
Marcin Jarzyna, Konrad Banaszek, Rafal Demkowicz-Dobrzanski
We analyze the ultimate quantum limit on the accessible information for an optical communication scheme when time bins carry coherent light pulses prepared in one of several orthog…

Matrix product states for quantum metrology
Marcin Jarzyna, Rafal Demkowicz-Dobrzanski
We demonstrate that the optimal states in lossy quantum interferometry may be efficiently simulated using low rank matrix product states. We argue that this should be expected in a…
