Random access Bell game by sequentially measuring the control of the quantum SWITCH
Gaurang Agrawal, Saptarshi Roy
Preserving quantum correlations such as Bell nonlocality in noisy environments remains a fundamental challenge for quantum technologies. We introduce the Random Access Bell Game (R…

Deriving the Generalised Born Rule from First Principles
Gaurang Agrawal, Matt Wilson
A basic postulate of modern compositional approaches to generalised physical theories is the generalised Born rule, in which probabilities are postulated to be computable from the…

Indefinite Time Directed Quantum Metrology
Gaurang Agrawal, Pritam Halder, Aditi Sen De
We explore the performance of the metrology scheme by employing a quantum time flip during encoding, a specific case of processes with indefinite time direction, which we refer to…
