Auxiliary-assisted energy distillation from quantum batteries
Paranjoy Chaki, Aparajita Bhattacharyya, Kornikar Sen +1
We discuss the idea of extracting energy from a quantum battery, applying a projective measurement on an auxiliary system. The battery is initially connected to the auxiliary syste…
Fundamental speed limits on entanglement dynamics of bipartite quantum systems
Vivek Pandey, Swapnil Bhowmick, Brij Mohan +2
The speed limits on entanglement are defined as the maximal rate at which entanglement can be generated or degraded in a physical process. We derive the speed limits on entanglemen…
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…
Quantifying the particle aspect of quantum systems
Sreetama Das, Indranil Chakrabarty, Arun Kumar Pati +2
The possibility of a quantum system to exhibit properties that are akin to both the classically held notions of being a particle and a wave, is one of the most intriguing aspects o…
Transient effects in quantum refrigerators with finite environments
Aparajita Bhattacharyya, Ahana Ghoshal, Ujjwal Sen
We explore a small quantum refrigerator consisting of three qubits, each of which is kept in contact with an environment. We consider two settings: one is when there is necessarily…
