Avoiding Entanglement Sudden Death Using Quantum Measurement Reversal on Single-qubit
Hyang‐Tag Lim, Jong Chan Lee, Kang-Hee Hong, Yoon-Ho Kim · 2015
Decoherence on two-qubit systems degrades entanglement, and sometimes even causes entanglement sudden death (ESD). We show quantum measurement reversal on only one subsystem can avoid ESD, providing methods for practical entanglement distribution under decoherence. (C) 2014 Optical Society of America
