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...
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...
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...
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...
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...
2006Vol.45No.2pp.271-274DOI: A New Quantum Communication Scheme by Using Bell States CAO Hai-Jing, CHEN Jing, and SONG He-Shan Department of Physics, Dalian University o...
2005Vol.44No.4pp.622-624DOI: 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...
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...
