Exponential tail estimates for quantum lattice dynamics
Christopher Cedzich, Alain Joye, Albert H. Werner +1
We consider the quantum dynamics of a particle on a lattice for large times. Assuming translation invariance, and either discrete or continuous time parameter, the distribution of…
Comment on "Experimental Test of Error-Disturbance Uncertainty Relations by Weak Measurement"
P. Busch, P. Lahti, R. F. Werner
In this comment on the paper by F. Kaneda, S.-Y. Baek, M. Ozawa and K. Edamatsu [Phys. Rev. Lett. 112, 020402, 2014, arXiv:1308.5868], we point out that the claim of having refuted…
Comment on "Noise and Disturbance in Quantum Measurements: An Information-Theoretic Approach"
P. Busch, P. Lahti, R. F. Werner
In this comment on the work of F. Buscemi, M.J.W. Hall, M. Ozawa and M.M. Wilde [PRL 112, 050401, 2014, arXiv:1310.6603], we point out a misrepresentation of measures of error and…
Measurement Uncertainty: Reply to Critics
P. Busch, P. Lahti, R. F. Werner
In a recent publication [PRL 111, 160405 (2013)] we proved a version of Heisenberg's error-disturbance tradeoff. This result was in apparent contradiction to claims by Ozawa of hav…
A short impossibility proof of Quantum Bit Commitment
G. Chiribella, G. M. D'Ariano, P. Perinotti +2
Bit commitment protocols, whose security is based on the laws of quantum mechanics alone, are generally held to be impossible on the basis of a concealment-bindingness tradeoff. A…
Quantum spin chains with quantum group symmetry
M. Fannes, B. Nachtergaele, R. F. Werner
We consider actions of quantum groups on lattice spin systems. We show that if an action of a quantum group respects the local structure of a lattice system, it has to be an ordina…
