Clifford Ergotropy
Somnath Maity, Ryusuke Hamazaki
We discuss the interplay between thermodynamics and magic resources in closed quantum dynamics by introducing Clifford ergotropy, the amount of extractable energy under the restric…
Quantum Error Mitigation Simulates General Non-Hermitian Dynamics
Hiroki Kuji, Suguru Endo, Tetsuro Nikuni +2
While non-Hermitian Hamiltonians enable exotic dynamical phenomena, implementing their nonunitary time evolution on near-term quantum devices remains challenging. We propose a hard…
Theory of Steady States for Lindblad Equations beyond Time-Independence: Classification, Uniqueness and Symmetry
Hironobu Yoshida, Ryusuke Hamazaki
We present a rigorous and comprehensive classification of the asymptotic behavior of time-dependent Gorini-Kossakowski-Sudarshan-Lindblad (GKSL) equations under the assumption of H…
Local spreading of stabilizer Rényi entropy in a brickwork random Clifford circuit
Somnath Maity, Ryusuke Hamazaki
Nonstabilizerness, or magic, constitutes a fundamental resource for quantum computation and a crucial ingredient for quantum advantage. Recent progress has substantially advanced t…
Optimal Work Extraction from Finite-Time Closed Quantum Dynamics
Shoki Sugimoto, Takahiro Sagawa, Ryusuke Hamazaki
Extracting useful work from quantum systems is a fundamental problem in quantum thermodynamics. In scenarios where rapid protocols are desired -- whether due to practical constrain…
Quasiprobability Thermodynamic Uncertainty Relation
Kohei Yoshimura, Ryusuke Hamazaki
We derive a quantum extension of the thermodynamic uncertainty relation where dynamical fluctuations are quantified by the Terletsky-Margenau-Hill quasiprobability, a quantum gener…
