One Bit of Collective Information Is Worth N ln 2 Bits of Local Information in a Many-Body Quantum Battery
Akoramurthy B, Surendiran B, Xiaochun Cheng
Charging a quantum battery through a collective non-adiabatic stroke stores energy in a shared bosonic mode, but part remains locked in correlations with the collective spin and is…

Exceptional-Point-Anchored Variational Quantum Eigensolver for Non-Hermitian Many-Body Phase Diagrams: Bridging Skin-Effect Topology and Entanglement Criticality on NISQ Hardware
Akoramurthy B, Surendiran B, Xiaochun Cheng
We introduce the Biorthogonal Variational Quantum Eigensolver (B-VQE), a quantum algorithm for simulating non-Hermitian many-body systems on noisy intermediate-scale quantum (NISQ)…
