Comment on Semiquantum-key distribution quantum states
2010/11/8
Recently Boyer and Mor pointed out the first conclusion of Lemma 1 in our original paper is not correct, and therefore, the proof of Theorem 5 based on Lemma 1 is wrong. Furthermore, they gave a direc...
Gaussification of quantum states of traveling light beams in atomic memory
Gaussification quantum states atomic memory
2010/10/21
We propose and investigate a protocol for Gaussification of quantum states of traveling light
beams in an atomic quantum memory that couples to light via quantum non-demolition interaction.
The prot...
Entanglement evolution of continuous variable quantum states
Entanglement evolution continuous variable quantum states
2010/3/10
We show when one of the modes of a initially bipartite Gaussian pure state interacts with a Gaussian noisy channel $\uppercase\expandafter{\romannumeral1}\otimes \$$, the evolution of entanglement can...
Analysis of Effectiveness of Lyapunov Control for Non-generic Quantum States
Analysis Lyapunov Control Non-generic Quantum States
2010/4/12
A Lyapunov-based control design for natural trajectory-tracking problems is analyzed for quantum states where the analysis in the generic case is not applicable. Using dynamical systems tools we show ...

The natural trajectory tracking problem is studied for generic quantum states represented by density operators. A control design based on the Hilbert-Schmidt distance as a Lyapunov function is conside...
Coherent Transport of Atomic Quantum States in a Scalable Shift Register
Coherent Transport Atomic Quantum Scalable Shift Register
2010/4/8
The coherent storage and transport of atomic quantum systems in versatile potential geometries are key elements for the investigation of quantum information processing and quantum degenerate gases. In...
Monogamy and entanglement in tripartite quantum states
entanglement measure monogamy tripartite entanglement
2010/4/9
We present an interesting monogamy equation for $(2 \otimes 2 \otimes n)$-dimensional pure states, by which a quantity is found to characterize the tripartite entanglement with the GHZ type and W type...
