Decoherence Mitigation with Local NOT Gates in Multipartite Systems

Venkat Abhignan, Raghav Sundararaman, Shriram Pragash M +2

We study the entanglement dynamics of $n=2,3,4$-qubit Bell- and GHZ-type states under an amplitude-damping channel (ADC). We quantify multipartite entanglement using the genuine mu…
