Transferring quantum information between a quantum system with limited control and a quantum computer
Ryosuke Sakai, Akihito Soeda, Mio Murao
We consider a hybrid quantum system consisting of a qubit system continuously evolving according to its fixed own Hamiltonian and a quantum computer. The qubit system couples to a…
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…
Success-or-Draw: A Strategy Allowing Repeat-Until-Success in Quantum Computation
Qingxiuxiong Dong, Marco Túlio Quintino, Akihito Soeda +1
Repeat-until-success strategy is a standard method to obtain success with a probability which grows exponentially in the number of iterations. However, since quantum systems are di…
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…
Robust controllability of two-qubit Hamiltonian dynamics
Ryosuke Sakai, Akihito Soeda, Mio Murao +1
Quantum gates (unitary gates) on physical systems are usually implemented by controlling the Hamiltonian dynamics. When full descriptions of the Hamiltonians parameters is availabl…
Complexity of causal order structure in distributed quantum information processing and its trade-off with entanglement
Eyuri Wakakuwa, Akihito Soeda, Mio Murao
We prove a trade-off relation between the entanglement cost and classical communication complexity of causal order structure of a protocol in distributed quantum information proces…
