Quantum error correction fails for Hamiltonian models
Robert Alicki
It is argued that the existing schemes of fault-tolerant quantum computation designed for discrete-time models and based on quantum error correction fail for continuous-time Hamilt…
Note on multiple additivity of minimal Renyi entropy output of the Werner-Holevo channels
R. Alicki, M. Fannes
We give an elementary self-contained proof that the minimal entropy output of arbitrary products of channels is additive.
Thermodynamics of quantum informational systems - Hamiltonian description
Robert Alicki, Michal Horodecki, Pawel Horodecki +1
It is often claimed, that from a quantum system of d levels, and entropy S and heat bath of temperature T one can draw kT(ln d -S) amount of work. However, the usual arguments base…
Comments on "Fault-Tolerant Quantum Computation for Local Non-Markovian Noise"
Robert Alicki
In the recent paper Terhal and Burkard derived a threshold result for fault-tolerant quantum computation under the assumption of the non-Markovian noise and claimed to rebut the ob…
Isotropic quantum spin channels and additivity questions
Robert Alicki
The minimum entropy output is computed for rotationally invariant quantum channels acting on spin-1/2 and spin-1 systems. For the case of two parallel such channels and initial ent…
