Multi-particle Entanglement via Two-Particle Entanglementalso provide necessary and sufficient conditions in the case of pure states. By a surprising example, we show that such conditions are not sufficient for separability in the case of mixed states, suggesting entanglement of a strange type.

Quantum Entanglement and the Communication Complexity of the Inner Product Functioncomputing the inner product. The communication required for the former problem can then be bounded by an application of Holevo’s theorem. We also give a speciffic example of a probabilistic scenario where entanglement reduces the communication complexity of the inner product function by one bit.

Quantum Effects in Algorithms possibility: suppose that we have a quantum computer with an on/off switch, programmed ready to solve a decision problem. Then (in certain circumstances) the mere fact that the computer . have given the answer . it were run, is enough for us to learn the answer, even though the computer is in fact . run.

Quantum Computer Can Not Speed Up Iterated Applications of a Black Boxantum computer with oracle for . for all possible . faster than in time Ώ(.). This means that there is no general method of quantum speeding up of classical algorithms provided in such a general method a classical algorithm is regarded as iterated applications of a given black box.

Correlation between Correlations: Process and Time in Quantum Networkstion of temporal Bell-inequalities and quantum parallelism. Due to the strange web of correlations being built-up, specific measurement outcomes for the tape may refer to one or several preparation histories of the head. Specific families of correlation functions are more stable with respect to dissipation than the total wave-function.

Practical Free-Space Quantum Cryptographyveness of privacy amplification procedures is discussed. Our conclusions are that free-space QKD is both effective and secure; possible applications include the rekeying of satellites in low earth orbit.
