Photonic Simulation of Beyond-Quantum Nonlocal Correlations (e.g. Popescu-Rohrlich Box) with Non-Signaling Quantum Resources
Kunal Shukla, Anirudh Verma, Kanad Sengupta +3
Bell nonlocality exemplifies the most profound departure of quantum theory from classical realism. Yet, the extent of nonlocality in quantum theory is intrinsically bounded, fallin…

Deterministic quantum teleportation of a path-encoded state using entangled photons
Akshai T. Krishnan, Kanad Sengupta, S. P. Dinesh +1
Quantum teleportation enables a way to transmit an arbitrary qubit state from one place to an other. A standard scheme for teleportation in optical setup involve three photons, an…

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…
