Accelerated first detection in discrete-time quantum walks using sharp restarts
Kunal Shukla, Riddhi Chatterjee, C. M. Chandrashekar
Restart is a common strategy observed in nature that accelerates first-passage processes and has been extensively studied using classical random walks. In the quantum regime, resta…

Quantum Speed Limit in Driven-dissipative Systems
Sarfraj Fency, Riddhi Chatterjee, Rangeet Bhattacharyya
Every quantum operation that takes a system from one state to another is known to have bounds on operation time, due to Heisenberg uncertainty principle. In open quantum systems (O…
