Engineering two-qubit mixed states with weak measurements
arXiv:2006.08190 · doi:10.1103/PhysRevResearch.2.042014
Abstract
It is known that protocols based on weak measurements can be used to steer quantum systems into pre-designated pure states. Here we show that weak-measurement-based steering protocols can be harnessed for on-demand engineering of states. In particular, through a continuous variation of the protocol parameters, one can guide a classical target state to a discorded one, and further on, towards an entangled target state.
