Deterministic Quantum Phase Estimation with Linear Circuit Complexity in a Photonic System
M. Midhuna, Ajay Jayachandran, Kanad Sengupta +2
Quantum algorithms solve certain computational problems faster than the best known classical algorithms. Many algorithms, including Shor's for factoring, Grover's for unstructured…
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…
Four-qubit photonic system for publicly verifiable quantum random numbers and generation of public and private key
Mayalakshmi Kolangatt, Anirudh Verma, Sujai Matta +2
We theoretically propose and experimentally demonstrate the use of a configurable four-qubit photonic system to generate a publicly verifiable quantum random numbers, to perform en…
