Towards minimal conditions for ergotropy injection in open quantum systems
Deependra Singh, Debarupa Saha, Ujjwal Sen
Interactions between a quantum system and its environment can inject ergotropy into the system, raising the question of the minimal dimensionality and physical resources required f…
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…
Enhanced quantum state discrimination under general measurements with entanglement and nonorthogonality restrictions
Swati Choudhary, Aparajita Bhattacharyya, Ujjwal Sen
The minimum error probability for distinguishing between two quantum states is bounded by the Helstrom limit, derived under the assumption that measurement strategies are restricte…
Precision Enhancement in Transient Quantum Thermometry:Cold-Probe Bias and Its Removal
Debarupa Saha, Ujjwal Sen
We unveil a fundamental temperature bias in transient quantum thermometry under Markovian dynamics. For qubit probes evolving in a thermal Markovian environment, we prove that tran…
