Decoherence Mitigation by Embedding a Logical Qubit in a Qudit
Hideyuki Miyahara, Yiyou Chen, Vwani Roychowdhury +1
Quantum information stored in a qubit is rapidly lost to the environment. The realization of robust qubits is one of the most important challenges in quantum computing. Herein we p…
Quantum Expectation-Maximization Algorithm
Hideyuki Miyahara, Kazuyuki Aihara, Wolfgang Lechner
Clustering algorithms are a cornerstone of machine learning applications. Recently, a quantum algorithm for clustering based on the k-means algorithm has been proposed by Kerenidis…
Many-body perturbation theory and fluctuation relations for interacting population dynamics
Hideyuki Miyahara
Population dynamics deals with the collective phenomena of living organisms, and it has attracted much attention since it is expected to explain how not only living organisms but a…
Work relations with measurement and feedback control on nonuniform temperature systems
Hideyuki Miyahara, Kazuyuki Aihara
The relation between the work performed to a system and the change of its free energy during a certain process is important in nonequilibrium statistical mechanics. In particular,…
Development of a two-particle self-consistent method for multi-orbital systems and its application to unconventional superconductors
Hideyuki Miyahara, Ryotaro Arita, Hiroaki Ikeda
We extend the two-particle self-consistent method proposed by Vilk and Tremblay (J. Phys. I France 7, 1309-1368 (1997)) to study superconductivity in multi-orbital systems. Startin…
