Geometric entangling gates for coupled cavity system in decoherence-free subspaces
Yue-Yue Chen, Xun-Li Feng, C. H. Oh
We propose a scheme to implement geometric entangling gates for two logical qubits in a coupled cavity system in decoherence-free subspaces. Each logical qubit is encoded with two…
Trapping a particle of a quantum walk on the line
Antoni Wojcik, Tomasz Luczak, Pawel Kurzynski +3
We observe that changing a phase at a single point in a discrete quantum walk results in a rather surprising localization effect. For certain values of this phase change the possib…
Linear optical scheme for producing polarization-entangled NOON states
Su-Yong Lee, Tomasz Paterek, Hee Su Park +1
We propose a linear optical scheme that can conditionally generate high NOON states using polarization modes. This scheme provides advantages over the previous proposals on path-en…
Information Causality
Marcin Pawłowski, Valerio Scarani
We review the literature on Information Causality. Since it's for a book, we don't think an abstract will be needed at all, so we have written this one just for the sake of the arX…
Ground-State Spaces of Frustration-Free Hamiltonians
Jianxin Chen, Zhengfeng Ji, David Kribs +2
We study the ground-state space properties for frustration-free Hamiltonians. We introduce a concept of `reduced spaces' to characterize local structures of ground-state spaces. Fo…
The classical-quantum boundary for correlations: discord and related measures
Kavan Modi, Aharon Brodutch, Hugo Cable +2
One of the best signatures of nonclassicality in a quantum system is the existence of correlations that have no classical counterpart. Different methods for quantifying the quantum…
