Avoiding entanglement sudden death on two-qubit systems using single-qubit quantum measurement reversal
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 that quantum measurement reversal on only one subsystem can avoid ESD, providing methods for practical entanglement distribution under decoherence.
