Temporal steering of entanglement decay with single-shot control

Saumya Ranjan Behera, Kallol Sen, Animesh Sinha Roy +4

Entanglement in open quantum systems can vanish abruptly through entanglement sudden death (ESD) under dissipative evolution, posing a challenge for quantum technologies. Here, we…
