Evidencing Macroscopic Quantum Coherence using Confined Uniform Magnetic Field
Dipankar Home, Harsh Talwar, Nilaj Saha +2
A previously unexplored scheme is devised for creating and certifying coherent quantum superposition of distinctly separated states of a spin-tagged massive object passing through…
Maximizing Nonclassicality of Massive Objects via Quantum Zeno Effect
Debarshi Das, Pritam Roy, Marko Toroš +3
For testing quantum mechanics in the macroscopic domain, a major challenge is to devise effective means for enhancing the observable nonclassical signatures despite the ubiquitous…
Intraparticle entanglement-based Random Access Code protocols: Contextuality-enabled quantum advantage and implications
Nilaj Saha, Sumit Mukherjee, Dipankar Home
We provide the first explicit identification and quantitative characterization of the physical origin of the quantum advantage in the Random Access Code (RAC) protocol. This is ach…
Near perfect noisy quantum teleportation by one-sided environment engineering
Md Manirul Ali, Sovik Roy, Dipankar Home
Achieving near-unity fidelity of Quantum Teleportation (QT) in a noisy environment is an essential requirement for its real-world applications. Towards this goal, we devise a disti…
