Conclusive qudit states transformation implemented by remote parters

Hong LU, LiBing CHEN

Alice, Cindy, and Bob are three remote parties. We present a scheme which allows Alice and Cindy to transform probabilistically and conclusively Bob's unknown d-level quantum (qudit) state into another. In this scheme, the remote positive operator valued measurements (POVM) lies at the heart. Based on the knowledge of probability amplitudes and phase factors of Bob's original state and target state, Alice and Cindy could construct jointly the required optimal POVM, which acts remotely on Bob's (2d-1)-dimensional direct sum space. We construct a quantum network for realizing the remote POVM with 2(d-1) remote two-level unitary rotations, and thus provide a feasible physical means to realize the remote POVM. The fact that the remote POVM could be realized using only 2(d-1) two-level Bell states (ebits) and 3(d-1) two-level classical communications (cbits) is notable. This scheme can be generalized to implement conclusively the (N+2)-party remote qudit state transformation via (d-1) (N+1)-body two-level GHZ states, in which the phase factors of Bob's original state and target state are shared jointly by N agents. The success probability of implementing this remote state transformation is also investigated. This scheme is simpler but conclusive, and more efficient but with less resource, which will make it more feasible with the current experimental technology and more suitable for large-scale quantum network.

Quantum entanglement and classical separability in NMR computing

A. R. Kessel, Vladimir L. Ermakov

In the discussion about the quantumness of NMR computation a conclusion is done that computational states are separable and therefore can not be entangled. This conclusion is based on the assumption that the initial density matrix of an individual molecule coincides with whole sample molecules distribution over single molecule energy levels. This means that quantum stochasticity is replaced by classical stochasticity. In the present paper it is shown, that quantum NMR computation can create genuine entangled states if initial system states are thermodynamical equilibrium ones. A separability analysis problem can arise when one interprets the readout signal from whole sample.
