Developing universal logical state-purification strategy for quantum error correcting codes
Chandrima B. Pushpan, Tanoy Kanti Konar, Aditi Sen De +1
We develop a measurement-based protocol for simultaneously purifying arbitrary logical states in multiple quantum error correcting codes with unit fidelity and finite probability,…

Constructive impact of Wannier-Stark field on environment-boosted quantum batteries
Animesh Ghosh, Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju +1
Using the ground states of the Bose- and Fermi-Hubbard model as the battery's initial state, we demonstrate that using the Wannier-Stark (WS) field for charging in addition to onsi…

Measurement-based qudit quantum refrigerator with subspace cooling
Debkanta Ghosh, Tanoy Kanti Konar, Aditi Sen De
We develop a method to transform a collection of higher-dimensional spin systems from the thermal state with a very high temperature of a local spin-s Hamiltonian to a low-lying en…
