Quantum error correction via purification using a single auxiliary
Chandrima B. Pushpan, Tanoy Kanti Konar, Aditi Sen De +1
We propose a single auxiliary-assisted purification-based framework for quantum error correction, capable of correcting errors that drive a system from its ground-state subspace in…
Bridging the daemonic gap en route to charge multi-mode batteries via a single auxiliary
Chandrima B. Pushpan, Amit Kumar Pal
We show that harnessing daemonic advantage is possible while charging a quantum battery by first time-evolving the battery collectively with an auxiliary charger, followed by an en…
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,…
Simultaneous cooling of qubits via a quantum absorption refrigerator and beyond
Jithin G. Krishnan, Chandrima B. Pushpan, Amit Kumar Pal
We design a quantum thermal device that can simultaneously and dynamically cool multiple target qubits. Using a setup with three bosonic heat baths, we propose an engineering of in…
