Balancing error budget for fermionic k-RDM estimation
Nayuta Takemori, Yusuke Teranishi, Wataru Mizukami +1
The reduced density matrix (RDM) is crucial in quantum many-body systems for understanding physical properties, including all local physical quantity information. This study aims t…
Work extractability from energy eigenstates under optimized local operations
Shotaro Z. Baba, Nobuyuki Yoshioka, Takahiro Sagawa
We examine the relationship between the second law of thermodynamics and the energy eigenstates of quantum many-body systems that undergo cyclic unitary evolution. Using a numerica…
Nonlinearity-induced topological phase transition characterized by the nonlinear Chern number
Kazuki Sone, Motohiko Ezawa, Yuto Ashida +2
As first demonstrated by the characterization of the quantum Hall effect by the Chern number, topology provides a guiding principle to realize robust properties of condensed matter…
Leveraging hardware-control imperfections for error mitigation via generalized quantum subspace
Yasuhiro Ohkura, Suguru Endo, Takahiko Satoh +2
In the era of quantum computing without full fault-tolerance, it is essential to suppress noise effects via the quantum error mitigation techniques to enhance the computational pow…
Quantum Fluctuation Theorem under Continuous Measurement and Feedback
Toshihiro Yada, Nobuyuki Yoshioka, Takahiro Sagawa
While the fluctuation theorem in classical systems has been thoroughly generalized under various feedback control setups, an intriguing situation in quantum systems, namely under c…
