Improvement of Speed Limits: Quantum Effect on the Speed in Open Quantum Systems
Kotaro Sekiguchi, Satoshi Nakajima, Ken Funo +1
In the context of quantum speed limits, it has been shown that the minimum time required to cause a desired state conversion via the open quantum dynamics can be estimated using th…
Symmetry induced enhancement in finite-time thermodynamic trade-off relations
Ken Funo, Hiroyasu Tajima
Symmetry imposes constraints on open quantum systems, affecting the dissipative properties in nonequilibrium processes. Superradiance is a typical example in which the decay rate o…
Speed-Accuracy Trade-Off Relations in Quantum Measurements and Computations
Satoshi Nakajima, Hiroyasu Tajima
In practical measurements, it is widely recognized that reducing the measurement time leads to decreased accuracy. However, whether an inherent speed-accuracy trade-off exists as a…
Gibbs-preserving operations requiring infinite amount of quantum coherence
Hiroyasu Tajima, Ryuji Takagi
Gibbs-preserving operations have been studied as one of the standard free processes in quantum thermodynamics. Although they admit a simple mathematical structure, their operationa…
