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…
Quantum advantage unlocked: Charging quantum batteries with K-regular graph stabilizers
Debkanta Ghosh, Tanoy Kanti Konar, Gianluca Francica +2
Regular graphs find broad applications ranging from quantum communication to quantum computation. Motivated by this, we investigate the design of a quantum battery based on a K-reg…
Block entanglement bounds distribution of regionally localized entanglement
Jithin G. Krishnan, Aditi Sen De, Amit Kumar Pal
In quantum networks, eliminating connections between nodes is crucial to mitigate the effects of decoherence, often achieved by performing measurements on nodes that are idle, or v…
Scaling of entanglement entropy and correlations in the variable-range extended Ising model
Harikrishnan K J, Debasis Sadhukhan, Amit Kumar Pal
We study the two-point correlation functions and the bipartite entanglement in the ground state of the exactly-solvable variable-range extended Ising model of qubits in the presenc…
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,…
