Codes for Quantum Secret Sharing with a Helper
Eric Chitambar, Sarah Hagen, David W. Kribs +3
Helper quantum secret sharing is a form of secret sharing defined by its unique access structure. One special fixed party, called the helper, can work together with any other party…
Quantum Secret Sharing with a Helper and Programmable Access Structures
Eric Chitambar, Sarah Hagen, David W. Kribs +2
Quantum secret sharing (QSS) is a process in which the state of a quantum system is partitioned into multiple shares, allowing only specific subsets of shareholders to reconstruct…
Structure Theorem for Quantum Replacer Codes
Eric Chitambar, Sarah Hagen, David W. Kribs +2
Quantum replacer codes are codes that can be protected from errors induced by a given set of quantum replacer channels, an important class of quantum channels that includes the era…
Implementing Quantum Secret Sharing on Current Hardware
Jay Graves, Mike Nelson, Eric Chitambar
Quantum secret sharing is a cryptographic scheme that enables a secure storage and reconstruction of quantum information. While the theory of secret sharing is mature in its develo…
