Characterizing quantum precision enhancement for multiple currents in open quantum systems
Khalak Mahadeviya, Sheikh Parvez Mandal, Mahasweta Pandit +3
The kinetic uncertainty relation (KUR) constrains fluctuations of individual currents in classical nonequilibrium systems in terms of the dynamical activity, which quantifies the a…
Bath memory as a precision resource in quantum transport
José Molina, Sheikh Parvez Mandal, Mahasweta Pandit +1
Structured baths can reshape transport fluctuations in mesoscopic quantum devices, yet a predictive criterion for when this enhances precision has been lacking. We propose a route…
Autonomous oscillations in quantum electromechanics: tensor network treatment
Mahasweta Pandit, Sheikh Parvez Mandal, Mark T. Mitchison +1
Transport-induced self-sustained oscillations in electromechanical systems convert a static electrochemical bias into robust, autonomous oscillatory motion in the absence of any ex…
Remote predictability of quantum measurement outcomes
Chirag Srivastava, Aparajita Bhattacharyya, Sheikh Parvez Mandal +2
Predicting quantum measurement outcomes for a local observer makes sense before, but not after, the measurement. However, for a remote observer, predicting measurement outcomes eve…
Exclusion principle for nonlocal advantage of quantum coherence
Priya Ghosh, Mahasweta Pandit, Chirag Srivastava +1
Coherences in mutually unbiased bases of states of an isolated quantum system follow a complementarity relation. The nonlocal advantage of quantum coherence (NAQC), defined in a bi…
Quantitative non-classicality of mediated interactions
Ray Ganardi, Ekta Panwar, Mahasweta Pandit +2
In plethora of physical situations one can distinguish a mediator -- a system that couples other, non-interacting systems. Often the mediator itself is not directly accessible to e…
Sequential detection of genuine multipartite entanglement is unbounded for entire hierarchy of number of qubits recycled
Chirag Srivastava, Mahasweta Pandit, Ujjwal Sen
Experimental detection of entanglement certainly disturbs the underlying shared state. It is possible that the entanglement content of the system is lost in the process of its dete…
Optimal tests of genuine multipartite nonlocality
Mahasweta Pandit, Artur Barasinski, Istvan Marton +2
We propose an optimal numerical test for genuine multipartite nonlocality based on linear programming. In particular, we consider two non-equivalent models of local hidden variable…
Recycled detection of genuine multiparty entanglement of unlimitedly stretched array of parties and arbitrarily long series of sequential observers
Chirag Srivastava, Mahasweta Pandit, Ujjwal Sen
We consider a scenario where spatially separated observers share a genuinely multiparty entangled quantum state with each local observer possessing a single qubit. A particular qub…
Recycled entanglement detection by arbitrarily many sequential and independent pairs of observers
Mahasweta Pandit, Chirag Srivastava, Ujjwal Sen
We investigate the witnessing of two-qubit entangled states by sequential and independent pairs of observers, with both observers of each pair acting independently on their part of…
Entanglement witnessing by arbitrarily many independent observers recycling a local quantum shared state
Chirag Srivastava, Mahasweta Pandit, Ujjwal Sen
We investigate the scenario where an observer, Alice, shares a two-qubit state with an arbitrary number of observers, Bobs, via sequentially and independently recycling the qubit i…
Simultaneous estimation of multiple phases in generalised Mach-Zehnder interferometer
Marcin Markiewicz, Mahasweta Pandit, Wieslaw Laskowski
In this work we investigate the problem of simultaneous estimation of phases using generalised three- and four-mode Mach-Zehnder interferometer. In our setup, we assume that the ph…
Cooperation and dependencies in multipartite systems
Waldemar Klobus, Marek Miller, Mahasweta Pandit +7
We propose an information-theoretic quantifier for the advantage gained from cooperation that captures the degree of dependency between subsystems of a global system. The quantifie…
-uniform mixed states
Waldemar Klobus, Adam Burchardt, Adrian Kolodziejski +4
We investigate the maximum purity that can be achieved by k-uniform mixed states of N parties. Such N-party states have the property that all their k-party reduced states are maxim…
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…
Effects of cavity-cavity interaction on the entanglement dynamics of a generalized double Jaynes-Cummings model
Mahasweta Pandit, Sreetama Das, Sudipto Singha Roy +2
We consider a generalized double Jaynes-Cummings model consisting of two isolated two-level atoms, each contained in a lossless cavity, with the cavities interacting with each othe…
