Demonstration of Einstein–Podolsky–Rosen Steering with Multiple Observers via Sequential Measurements
Jian Li, Zhou Yang, Qin Wang · Chinese Physics Letters · 2022
Quantum correlation is a fundamental property that distinguishes quantum systems from classical ones, and is also a fragile resource under projective measurements. Recently, it has been shown that a subsystem in entangled pairs can share nonlocalities with multiple observers in sequence. Here we present a new steering scenario where both subsystems are accessible by multiple observers. Simulation results show that the two qubits in a singlet state can be simultaneously steered separately by two sequential observers.
