Induced Coherence in Quantum and Classical Interferometry: Origin and Control
Balakrishnan Viswanathan, Ravi Kamal Pandey, Devendra Kumar Mishra +2
The wave-particle duality that manifests in the Young's double-slit interferometry satisfying the well known Englert-Greenberger-Yasin inequality has recently been shown to obey a…
Verification of continuous variable entanglement with undetected photons
Sanjukta Kundu, Balakrishnan Viswanathan, Pawel Szczypkowski +3
We verify transverse spatial entanglement of photon-pairs generated in spontaneous parametric down conversion using a nonlinear interferometric technique without relying on any coi…
Heralded Induced-Coherence Interferometry in a Noisy Environment
L. Theerthagiri, Balakrishnan Viswanathan, C. M. Chandrashekar
Induced-coherence interferometry, first introduced in the Zou-Wang-Mandel (ZWM) setup, enables retrieval of object information from the interference pattern of light that never int…
Auxiliary-state facilitated phase synchronization phenomena in isolated spin systems
Xylo Molenda, S. Zhong, B. Viswanathan +4
Extending classical synchronization to the quantum domain is of great interest both from the fundamental physics point of view and with a view toward quantum technology application…
