Optimal quantum discrimination of single-qubit unitary gates between two candidates
Akihito Soeda, Atsushi Shimbo, Mio Murao
We analyze a discrimination problem of a single-qubit unitary gate with two candidates, where the candidates are not provided with their classical description, but their quantum sa…
Probabilistic exact universal quantum circuits for transforming unitary operations
Marco Túlio Quintino, Qingxiuxiong Dong, Atsushi Shimbo +2
This paper addresses the problem of designing universal quantum circuits to transform uses of a -dimensional unitary input-operation into a unitary output-operation in a pro…
Reversing Unknown Quantum Transformations: Universal Quantum Circuit for Inverting General Unitary Operations
Marco Túlio Quintino, Qingxiuxiong Dong, Atsushi Shimbo +2
Given a quantum gate implementing a -dimensional unitary operation , without any specific description but , and permitted to use times, we present a universal probab…
Equivalence determination of unitary operations
Atsushi Shimbo, Akihito Soeda, Mio Murao
We study equivalence determination of unitary operations, a task analogous to quantum state discrimination. The candidate states are replaced by unitary operations given as a quant…
