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…
Comparing coherence measures for X states: Can quantum states be ordered based on quantum coherence?
Sandeep Mishra, Kishore Thapliyal, Anirban Pathak +1
Quantum coherence is an essential resource for quantum information processing and various quantitative measures of it have been introduced. However, the interconnections between th…
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…
A Simplified Hierarchical Dynamic Quantum Secret Sharing Protocol with Added Features
Sandeep Mishra, Chitra Shukla, Anirban Pathak +2
Generalizing the notion of dynamic quantum secret sharing (DQSS), a simplified protocol for hierarchical dynamic quantum secret sharing (HDQSS) is proposed and it is shown that the…
Controlling wave function localization in a multiple quantum well structure
Anjana Bagga, Anu Venugopalan
The dynamics of a wave function describing a particle confined in a multiple quantum well potential is studied numerically. As a consequence of quantum mechanical tunneling, an ini…
