On quantum estimation, quantum cloning and finite quantum de Finetti theorems
Giulio Chiribella
This paper presents a series of results on the interplay between quantum estimation, cloning and finite de Finetti theorems. First, we consider the measure-and-prepare channel that…
Computational Difficulty of Computing the Density of States
Brielin Brown, Steven T. Flammia, Norbert Schuch
We study the computational difficulty of computing the ground state degeneracy and the density of states for local Hamiltonians. We show that the difficulty of both problems is exa…
Quantum Computing
Thaddeus D. Ladd, Fedor Jelezko, Raymond Laflamme +3
Quantum mechanics---the theory describing the fundamental workings of nature---is famously counterintuitive: it predicts that a particle can be in two places at the same time, and…
Quantum computational capability of a 2D valence bond solid phase
Akimasa Miyake
Quantum phases of naturally-occurring systems exhibit distinctive collective phenomena as manifestation of their many-body correlations, in contrast to our persistent technological…
Quantum Capacity Approaching Codes for the Detected-Jump Channel
Markus Grassl, Zhengfeng Ji, Zhaohui Wei +1
The quantum channel capacity gives the ultimate limit for the rate at which quantum data can be reliably transmitted through a noisy quantum channel. Degradable quantum channels ar…
Extending Quantum Coherence in Diamond
C. A. Ryan, J. S. Hodges, D. G. Cory
We experimentally demonstrate over two orders of magnitude increase in the coherence time of nitrogen vacancy centres in diamond by implementing decoupling techniques. We show that…
