Decoherence and Visibility Enhancement in Multi-Path Interference
Sandeep Mishra, Anu Venugopalan, Tabish Qureshi
We theoretically analyze the observations reported in a four-path quantum interference experiment via multiple beam Ramsey interference [Phys. Rev. Lett. 86, 559 (2001)]. In this e…

Monitoring Decoherence via Measurement of Quantum Coherence
Anu Venugopalan, Sandeep Mishra, Tabish Qureshi
A multi-slit interference experiment, with which-way detectors, in the presence of environment induced decoherence, is theoretically analyzed. The effect of environment is modeled…

Bell States via Two-Particle Contact Interaction: Shannon Entropy as an Indicator of Entanglement Dynamics
Sandeep Mishra, Anjana Bagga, Anu Venugopalan
We study the coherent dynamics of two interacting particles in a quantum double-well and show that the Shannon entropy can be a definitive signature of entanglement as an alternati…
