Freezing quantum coherence with weak measurement

Not Accessible

Your library or personal account may give you access


We show how to optimally protect quantum states and freeze coherence under incoherent channels using a quantum weak measurement and quantum measurement reversal. In particular, we present explicit formulas for the conditions for freezing quantum coherence in a given quantum state.
