Efficient utilization of imaginarity in quantum steering
Shounak Datta, A. S. Majumdar
We illustrate the role of complex numbers in quantum information processing through the phenomenon of quantum steering. Exploiting partial knowledge of a qubit in terms of imaginar…
Anharmonicity can enhance the performance of quantum refrigerators
Sourav Karar, Shounak Datta, Sibasish Ghosh +1
We explore a thermodynamical effect of anharmonicity in quantum mechanical oscillators. We show that small quartic perturbations to the oscillator potential lead to an enhancement…
Protecting temporal correlations of two-qubit states using quantum channels with memory
Shounak Datta, Shiladitya Mal, A. S. Majumdar
Quantum temporal correlations exhibited by violations of Leggett-Garg Inequality (LGI) and Temporal Steering Inequality (TSI) are in general found to be non-increasing under decohe…
Preservation of quantum non-bilocal correlations in noisy entanglement-swapping experiments using weak measurements
Shashank Gupta, Shounak Datta, A. S. Majumdar
A tripartite quantum network is said to be bilocal if two independent sources produce a pair of bipartite entangled states. Quantum non-bilocal correlation emerges when the central…
Sharing of Non-Local Advantage of Quantum Coherence by sequential observers
Shounak Datta, A. S. Majumdar
Non-local Advantage of Quantum Coherence(NAQC) or steerability of local quantum coherence is a strong non-local resource based on coherence complementarity relations. In this work,…
Tighter Einstein-Podolsky-Rosen steering inequality based on the sum uncertainty relation
Ananda G. Maity, Shounak Datta, A. S. Majumdar
We consider the uncertainty bound on the sum of variances of two incompatible observables in order to derive a corresponding steering inequality. Our steering criterion when applie…
