Blind-spots of Randomized Benchmarking Under Temporal Correlations

Varun Srivastava, Abhinash Kumar Roy, Soumik Mahanti +3

Randomized benchmarking (RB) is a widely adopted protocol for estimating the average gate fidelity in quantum hardware. However, its standard formulation relies on the assumption o…

Hamiltonian characterisation of multi-time processes with classical memory

Kaumudibikash Goswami, Abhinash Kumar Roy, Varun Srivastava +4

A central problem in open quantum systems is the characterization of non-Markovian processes, where an environment retains the memory of its interaction with the system. A key dist…
