Connecting Density Matrix Spectroscopy to Biexciton Entanglement Dynamics
Yusuke Masaki, Takashi Otaki, Hiroaki Matsueda
Quantum entanglement is one of the most intriguing features of quantum mechanics. To investigate the entanglement between two excitons in a biexciton, an experimental technique cal…
Theoretical analysis of photon detection mechanism in superconducting single-photon detectors
Yusuke Masaki, Hiroaki Matsueda
To elucidate the photon detection mechanism of superconducting single-photon detectors, we theoretically examine the dynamics of type-II superconductors with a bias current using t…
Nonlocal correlations in quantum energy teleportation: perspectives from their Majorana representations and information thermodynamics
Hiroaki Matsueda, Yusuke Masaki, Kanji Itoh +2
Motivated by anomalous nonlocal correlation in the Kitaev spin liquids, we propose a quantum energy teleportation protocol between remote partners Alice and Bob on a quantum spin m…
Upper Bound on Locally Extractable Energy from Entangled Pure State under Feedback Control
Kanji Itoh, Yusuke Masaki, Hiroaki Matsueda
We introduce an effective thermodynamics for multipartite entangled pure states and derive an upper bound on extractable energy with feedback control from a subsystem under a local…
