Battery Locality Is Necessary in Noncommuting Quantum Charging Bounds
Sheryl Mathew
Bounds on the charging power of quantum batteries in direct charging protocols are often interpreted as charging-side constraints. Although the locality of the charging Hamiltonian…

Super-Extensive Charging Power in the Absence of Global Operations
Anupam, Sheryl Mathew, Sibasish Ghosh
Quantum batteries have emerged as a platform for investigating whether quantum effects can accelerate energy storage beyond classical limits. Although a variety of charging schemes…

Fault-tolerant hyperbolic Floquet quantum error correcting codes
Ali Fahimniya, Hossein Dehghani, Kishor Bharti +4
A central goal in quantum error correction is to reduce the overhead of fault-tolerant quantum computing by increasing noise thresholds and reducing the number of physical qubits r…
