Generalizing Choi map in beyond circulant scenario
Anindita Bera, Giovanni Scala, Gniewomir Sarbicki +1
We present a generalization of the family of linear positive maps in proposed thirty years ago by Cho et al. (Linear Algebra Appl. , 213 (1992)) as a generalizatio…
Thermodynamics and the quantum speed limit in the non-Markovian regime
Arpan Das, Anindita Bera, Sagnik Chakraborty +1
Quantum speed limit (QSL) for open quantum systems in the non-Markovian regime is analyzed. We provide a the lower bound for the time required to transform an initial state to a fi…
Growth of genuine multipartite entanglement in random unitary circuits
Anindita Bera, Sudipto Singha Roy
We study the growth of genuine multipartite entanglement in random quantum circuit models, which include random unitary circuit models and the random Clifford circuit. We find that…
One-shot conclusive multiport quantum dense coding capacities
Chirag Srivastava, Anindita Bera, Aditi Sen De +1
We introduce a probabilistic version of the one-shot quantum dense coding protocol in both two- and multiport scenarios, and refer to it as conclusive quantum dense coding. Specifi…
Witnessing entanglement sequentially: Maximally entangled states are not special
Anindita Bera, Shiladitya Mal, Aditi Sen De +1
We investigate sharing of bipartite entanglement in a scenario where half of an entangled pair is possessed and projectively measured by one observer, called Alice, while the other…
Position and momentum cannot both be lazy: Quantum reciprocity relation with Lipschitz constants
Mahasweta Pandit, Anindita Bera, Aditi Sen De +1
We propose a trade-off between the Lipschitz constants of the position and momentum probability distributions for arbitrary quantum states. We refer to the trade-off as a quantum r…
