Non-Markovian and Thermodynamic Signatures in the Classicality Assessment via Kolmogorov Consistency
Arghya Maity, Ahana Ghoshal, Kelvin Onggadinata +1
The Kolmogorov consistency condition (KCC) defines the statistical boundary between classical and quantum dynamics. Its violation signifies the breakdown of a classical Markov desc…
Quantum Heat Transformers
Arghya Maity, Paranjoy Chaki, Ahana Ghoshal +1
We propose a quantum heat transformer (QHT), a quantum thermodynamic device that modulates temperature gradients between two thermal junctions in quantum systems. Functionally, the…
Qubits in second quantisation in fermionic simulators
Ahana Ghoshal, Carlos de Gois, Kiara Hansenne +2
Simulating many-body fermionic systems in conventional qubit-based quantum computers poses significant challenges due to the overheads associated with the encoding of fermionic sta…
All multipartite entanglements are quantum coherences in locally distinguishable bases
Ahana Ghoshal, Swati Choudhary, Ujjwal Sen
We find that the m-separability and k-partite entanglement of a multipartite quantum system is correlated with quantum coherence of the same with respect to complete orthonormal ba…
Violation of the thermodynamic uncertainty relation in quantum collisional models
Arghya Maity, Ahana Ghoshal
The thermodynamic uncertainty relation (TUR) is a fundamental principle in non-equilibrium thermodynamics that relates entropy production to fluctuations in a system, establishing…
Role of phase of optimal probe in noncommutativity vs coherence in quantum multiparameter estimation
Ritopriyo Pal, Priya Ghosh, Ahana Ghoshal +1
Quantum multiparameter estimation offers a framework for the simultaneous estimation of multiple parameters, pertaining to possibly noncommutating observables. While the optimal pr…
