Kenta Koshihara

Kenta Koshihara serves as an Assistant Professor (non-tenure-track) at Waseda University's School of Advanced Science and Engineering, Japan, focusing on quantum thermodynamics and quantum information theory since 2024. He holds a Doctor of Science from Waseda University (2023) and maintains continuous institutional affiliation dating to 2014.

His academic background includes:

• Doctor of Science, Graduate School of Advanced Science and Engineering (2020-2023)
• Master's Program, Graduate School of Advanced Science and Engineering (2018-2020)
• Bachelor of Science, School of Advanced Science and Engineering, Department of Physics (2014-2018)

Koshihara's research centers on quantum thermodynamics, investigating how quantum measurement and feedback control enable work extraction in finite-time cycles. His work bridges open quantum systems, non-equilibrium statistical mechanics, and quantum information to establish thermodynamic limits in quantum heat engines, with particular emphasis on quantum ergotropy and Maxwell's demon paradigms. He explores how quantum coherence persists in non-Markovian environments and influences energy conversion efficiency.

Analysis of his 8 publications (2018-2023) reveals consistent focus on quantum feedback control mechanisms, with key contributions including extended thermodynamic inequalities for quantum cycles and proofs of work extraction limits in non-equilibrium steady states. His methodology combines quantum master equations with information-theoretic approaches to address fundamental constraints in quantum thermal machines.

Information regarding advised students and research grants is unavailable in the source materials.

He leads Waseda University's internal research project 'Thermodynamic Laws of Non-equilibrium Quantum Systems from Steady Cycles' (2024), developing theoretical frameworks for quantum heat engines operating under continuous measurement and feedback protocols.
