Measurement-free reconstruction circuit of quantum secrets in quantum secret sharing
Shogo Chiwaki, Ryutaroh Matsumoto
For a quantum secret sharing scheme built from a general quantum stabilizer code, no measurement-free circuit has been known for reconstructing its quantum secrets, except particul…
Advance Sharing Procedures for the Ramp Quantum Secret Sharing Schemes With the Highest Coding Rate
Ryutaroh Matsumoto
In some quantum secret sharing schemes, it is known that some shares can be distributed to participants before a secret is given to the dealer. However, it is unclear whether some…
Advance Sharing with Ogawa et al.'s Ramp Quantum Secret Sharing Scheme
Satoshi Masumori, Ryutaroh Matsumoto
The ramp quantum secret sharing proposed by Ogawa et al. has the highest possible coding rate given a threshold type access structure. On the other hand, in some quantum secret sha…
Advance sharing of quantum shares for quantum secrets
Mamoru Shibata, Ryutaroh Matsumoto
Secret sharing is a cryptographic scheme to encode a secret to multiple shares being distributed to participants, so that only qualified sets of participants can restore the origin…
Performance comparison of the two reconstruction methods for stabilizer-based quantum secret sharing
Shogo Chiwaki, Ryutaroh Matsumoto
Stabilizer-based quantum secret sharing has two methods to reconstruct a quantum secret: The erasure correcting procedure and the unitary procedure. It is known that the unitary pr…
Advance sharing of quantum shares for classical secrets
Rina Miyajima, Ryutaroh Matsumoto
Secret sharing schemes for classical secrets can be classified into classical secret sharing schemes and quantum secret sharing schemes. Classical secret sharing has been known to…
