An international team led by the University of Chicago’s Institute for Molecular Engineering has discovered how to manipulate a weird quantum interface between light and matter in silicon carbide alon...
Secure Quantum Communication and Superluminal Signalling on the Bell Channel
Bell Channel Quantum Communication and Superluminal Signalling
2011/9/1
A means and protocol is presented to send information on the Bell Channel to achieve the effect of superluminal signalling. The method is to use detection of a photon entangled state as one binary dig...
Efficient entanglement distribution for quantum communication against collective noise
Efficient entanglement distribution quantum communication against collective noise
2010/10/29
We present an efficient faithful entanglement distribution scheme for quantum communication against collective noise. Its setup is composed of polarizing beam splitters, half wave plates, polarization...
Integrated quantum memory for quantum communication
Optical memories Quantum communications
2015/6/10
We present the first demonstration of a quantum memory protocol in a waveguiding media, which is promising for high-speed, electro-optic control of quantum state evolution during storage, as well as i...
Quantum phase with no translational symmetry and its potentiality for quantum communication
Quantum phase symmetry quantum communication
2010/4/16
By the method of terahertz photo-voltaic spectroscopy we have found a quantum phase that possesses neither continuous nor discrete translational symmetry. The phase is originated from quantum Hall sta...
The role of chaos in quantum communication through a dynamical dephasing channel
quantum communication dynamical dephasing channel
2010/4/6
In this article we treat the subject of chaotic environments with few degrees of freedom in quantum communication by investigating a conservative dynamical map as a model of a dephasing quantum channe...
Trading classical communication, quantum communication, and entanglement in quantum Shannon theory
Trading classical communication quantum communication quantum Shannon theory
2010/4/9
We give optimal trade-offs between classical communication, quantum communication, and entanglement for processing information in the Shannon-theoretic setting. We first prove a "unit-resource" capaci...

No-relationship Between Impossibility of Faster-Than-Light Quantum Communication and Distinction of Ensembles with the Same Density Matrix
WANG Chuan,...
We review our recent work towards quantum communication in a solid-state environment with qubits carried by electron spins. We propose three schemes to produce spin-entangled electrons, where the requ...
Nondeterministic Quantum Query and Quantum Communication Complexities
quantum computing query complexity communication complexity nondeterminism
2010/10/18
We study nondeterministic quantum algorithms for Boolean functions f. Such algorithms have positive acceptance probability on input x iff f(x) = 1. In the setting of query complexity, we show that the...
