Ergodic and mixing quantum channels in finite dimensions

- D. Burgarth, G. Chiribella, V. Giovannetti, P. Perinotti, K. Yuasa
- Physics
- 20 October 2012

The paper provides a systematic characterization of quantum ergodic and mixing channels in finite dimensions and a discussion of their structural properties. In particular, we discuss ergodicity in… Expand

Modified Fowler-Nordheim field emission formulae from a nonplanar emitter model

- K. Yuasa, Ayumi Shimoi, I. Ohba, C. Oshima
- Chemistry, Physics
- 20 November 2002

Field emission formulae, current–voltage characteristics and energy distribution of emitted electrons, are derived analytically for a nonplanar (hyperboloidal) metallic emitter model. The traditional… Expand

Purification through Zeno-like measurements.

- H. Nakazato, Tomoko Takazawa, K. Yuasa
- Physics, MedicinePhysical review letters
- 8 January 2003

A series of frequent measurements on a quantum system (Zeno-like measurements) is shown to result in the "purification" of another quantum system in interaction with the former. Even though the… Expand

Preparation and entanglement purification of qubits through Zeno-like measurements

- H. Nakazato, M. Unoki, K. Yuasa
- Physics
- 25 February 2004

A method of purification, purification through Zeno-like measurements [H. Nakazato, T. Takazawa, and K. Yuasa, Phys. Rev. Lett. 90, 060401 (2003)], is discussed extensively and applied to a few… Expand

Generalized Adiabatic Theorem and Strong-Coupling Limits

- D. Burgarth, P. Facchi, H. Nakazato, S. Pascazio, K. Yuasa
- Physics, MathematicsQuantum
- 5 July 2018

We generalize Kato's adiabatic theorem to nonunitary dynamics with an isospectral generator. This enables us to unify two strong-coupling limits: one driven by fast oscillations under a Hamiltonian,… Expand

Quantum Estimation via Sequential Measurements

- D. Burgarth, V. Giovannetti, A. Kato, K. Yuasa
- Physics
- 28 July 2015

The problem of estimating a parameter of a quantum system through a series of measurements performed sequentially on a quantum probe is analyzed in the general setting where the underlying statistics… Expand

Bifurcation phenomenon in spin relaxation.

Stochastic limit approximation for rapidly decaying systems

- G. Kimura, K. Yuasa, K. Imafuku
- Physics
- 4 July 2000

The stochastic limit approximation method for ``rapid'' decay is presented, where the damping rate \gamma is comparable to the system frequency \Omega, i.e., \gamma \sim \Omega, whereas the usual… Expand

Estimating temperature via sequential measurements

- A. D. Pasquale, K. Yuasa, V. Giovannetti
- Physics
- 30 January 2017

We study the efficiency of estimation procedures where the temperature of an external bath is indirectly recovered by monitoring the transformations induced on a probing system that is put in thermal… Expand
