Gate-based emulation of boson sampling using photonic qubits
Aastha P. Zalone, S. P. Dinesh, C. M. Chandrashekar
Boson sampling arising from multiphoton interference in linear-optical networks is a prominent non-universal model for quantum computation. Here, by encoding the multi-qubit state…
Deterministic Quantum Phase Estimation with Linear Circuit Complexity in a Photonic System
M. Midhuna, Ajay Jayachandran, Kanad Sengupta +2
The paper presents a deterministic quantum phase estimation algorithm that reduces circuit depth from quadratic to linear for a specific class of unitary operators, and demonstrate…
A Quantum-Walk Representation of Color-Ordered MHV Scattering Amplitudes
Anirudh Verma, C. M. Chandrashekar
We introduce a graph-theoretic framework for representing color-ordered maximally helicity violating (MHV) scattering amplitudes in quantum chromodynamics using coined quantum walk…
Long distance quantum illumination and ranging using polarization entangled photon pairs in a lossy environment
Sujai Matta, Soumya Asokan, Sanchari Chakraborti +3
Using polarization entangled photon pairs, we demonstrate a robust scheme for quantum illumination and ranging in a lossy environment. Entangled photon pairs are generated in a Sag…
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…
Experimental realization of universal quantum gates and six-qubit entangled state using photonic quantum walk
Kanad Sengupta, S. P. Dinesh, K. Muhammed Shafi +2
For quantum computation using photons, performing deterministic quantum gate operations is a challenge due to the probabilistic nature of the photon-photon interaction. Encoding qu…
