Simultaneous Reduction of Observables and Measured Qudits in Entanglement-Assisted Quantum Local Recovery

Ryutaroh Matsumoto

For a general entanglement-assisted or unassisted quantum error-correcting code, a set of erasures, and an associated repair group, we propose a linear algebraic procedure to compu…

Entanglement assisted quantum $(r, δ)$ -locally recoverable codes

Carlos Galindo, Fernando Hernando, Helena Martín-Cruz +1

Quantum $(r, δ)$ -locally recoverable codes are quantum error-correcting codes capable of correcting $δ - 1$ qudit erasures within one subset of qudits of cardinality at most $r + δ - 1$ .…

Information locality of a quantum locally recoverable code

Ryutaroh Matsumoto

A classical linear code $C$ of length $n$ is said to have symbol locality $(r, δ)$ if for any index $j$ there exists a repair group $J_{j} \subseteq {1, \dots, n}$ with $j \in J_{j}$ …

Construction of Quantum Rank-Metric Codes Using Hermitian Orthogonality

Ryota Nizuka, Ryutaroh Matsumoto

Stacked quantum memory is an architecture in which multiple layers of qubits are stacked. Quantum rank-metric codes are effective for error correction in stacked quantum memories.…
