A graph-aware bounded distance decoder for all stabilizer codes
Harikrishnan K J, Amit Kumar Pal
We formulate a bounded distance decoding strategy applicable to all stabilizer codes including both CSS and non-CSS code-families. The framework emerges out of the local Clifford e…
Robust quantum metrology using disordered probes
Vishnupriya K., Harikrishnan K. J., Amit Kumar Pal
Disorder is ubiquitous in quantum devices including quantum probes designed and fabricated for quantum parameter estimation and sensing. We investigate the robustness of a quantum…
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…
