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…
Single system based generation of certified randomness using Leggett-Garg inequality
Pingal Pratyush Nath, Debashis Saha, Dipankar Home +1
We theoretically formulate and experimentally demonstrate a secure scheme for semi-device-independent quantum random number generation by utilizing Leggett-Garg inequality violatio…
Massive Spatial Qubits for Testing Macroscopic Nonclassicality and Casimir Induced Entanglement
Bin Yi, Urbasi Sinha, Dipankar Home +2
An open challenge in physics is to expand the frontiers of the validity of quantum mechanics by evidencing nonclassicality of the centre of mass state of a macroscopic object. Yet…
Uncovering a Nonclassicality of the Schrödinger Coherent State up to the Macro-Domain
S. Bose, D. Home, S. Mal
The Leggett-Garg inequality (LGI), based on the notions of realism and noninvasive measurability, is applied in the context of a linear harmonic oscillator. It is found that merely…
Bell measurements as a witness of a dualism in entanglement
E. Moreva, G. Brida, M. Gramegna +3
We show how a property of dualism, which can exist in the entanglement of identical particles, can be tested in the usual photonic Bell measurement apparatus with minor modificatio…
Exploring the role of Leggett-Garg inequality for quantum cryptography
Akshata Shenoy H., S. Aravinda, R. Srikanth +1
In the cryptographic context, an earlier unexplored application of the temporal version of the Bell-type inequality is shown here in the device-independent (DI) scenario. This is d…
Generic entanglement generation, quantum statistics and complementarity
S. Bose, D. Home
A general and an arbitrarily efficient scheme for entangling the spins (or any spin-like degree of freedom) of two independent uncorrelated identical particles by a combination of…
