Quantum walk-based protocol for secure communication between any two directly connected nodes on a network
Prateek Chawla, Adithi Ajith, C. M. Chandrashekar
The utilization of quantum entanglement as a cryptographic resource has superseded conventional approaches to secure communication. Security and fidelity of intranetwork communicat…
Quantum walks under superposition of causal order
Prateek Chawla, Shrikant Utagi, C. M. Chandrashekar
We set the criteria under which superposition of causal order can be incorporated in to quantum walks. In particular, we show that only periodic quantum walks or those with at leas…
Multi-bit quantum random number generator from path-entangled single photons
K. Muhammed Shafi, Prateek Chawla, Abhaya S. Hegde +3
Measurement outcomes on quantum systems exhibit inherent randomness and are fundamentally nondeterministic. This has enabled quantum physics to set new standards for the generation…
