Testing the equivalence to thermal states via extractable work under LOCC
Toshihiro Yada, Nobuyuki Yoshioka, Takahiro Sagawa
Understanding the thermal behavior of quantum many-body pure states is one of the most fundamental issues in quantum thermodynamics. It is widely known that typical pure states yie…
Non-Haar random circuits form unitary designs as fast as Haar random circuits
Toshihiro Yada, Ryotaro Suzuki, Yosuke Mitsuhashi +1
The unitary design formation in random circuits has attracted considerable attention due to its wide range of practical applications and relevance to fundamental physics. While the…
Thermodynamic approach to quantum cooling limit of continuous Gaussian feedback
Kousuke Kumasaki, Toshihiro Yada, Ken Funo +1
Feedback cooling plays a critical role in stabilizing quantum systems and achieving low temperatures, where a key question is to determine the fundamental thermodynamic limits on c…
Experimentally probing entropy reduction via iterative quantum information transfer
Toshihiro Yada, Pieter-Jan Stas, Aziza Suleymanzade +4
Thermodynamic principles governing energy and information are important tools for a deeper understanding and better control of quantum systems. In this work, we experimentally inve…
Measuring multipartite quantum correlations by thermodynamic work extraction
Toshihiro Yada, Nobuyuki Yoshioka, Takahiro Sagawa
Quantum correlations are at the core of quantum mechanics and play a crucial role in various fields. While bipartite quantum correlations have been extensively studied, multipartit…
