Quasi-Cyclic Constructions of Quantum Codes
Carlos Galindo, Fernando Hernando, Ryutaroh Matsumoto
We give sufficient conditions for self-orthogonality with respect to symplectic, Euclidean and Hermitian inner products of a wide family of quasi-cyclic codes of index two. We prov…
Two Gilbert-Varshamov Type Existential Bounds for Asymmetric Quantum Error-Correcting Codes
Ryutaroh Matsumoto
In this note we report two versions of Gilbert-Varshamov type existential bounds for asymmetric quantum error-correcting codes.
Quantum Optimal Multiple Assignment Scheme for Realizing General Access Structure of Secret Sharing
Ryutaroh Matsumoto
The multiple assignment scheme is to assign one or more shares to single participant so that any kind of access structure can be realized by classical secret sharing schemes. We pr…
Quantum Stabilizer Codes Can Realize Access Structures Impossible by Classical Secret Sharing
Ryutaroh Matsumoto
We show a simple example of a secret sharing scheme encoding classical secret to quantum shares that can realize an access structure impossible by classical information processing…
Unitary Reconstruction of Secret for Stabilizer Based Quantum Secret Sharing
Ryutaroh Matsumoto
We propose a unitary procedure to reconstruct quantum secret for a quantum secret sharing scheme constructed from stabilizer quantum error-correcting codes. Erasure correcting proc…
