This paper has been withdrawn by the authors due to a fatal flaw in the central proof.

This paper has been withdrawn by the author, due to a crucial error in the proof of Lemma 3.1.

This paper has been withdrawn by the author due to an error in an inequality in the proof of Theorem 1.1.

This paper has been withdrawn by the author, due a crucial error in the optimization. For the last one month I have been trying to remove the error, but it seems to take a lot of time so I decided to withdraw this paper for the moment.

We consider the task of distinguishing whether a quantum system is prepared in a state from one of several sets of quantum states. Assuming their convexity and stability under tensor product, we prove that the optimal error exponent for…

This paper has been withdrawn by the author due to an error.

This paper has been withdrawn by the author due to an error estimate in Lemma 3.1.

This paper has been withdrawn by the author due to a sheaf-theoretic error, in the end of the proof of the main theorem.

This paper has been withdrawn by the author due to a crucial sign error in equation 1.

This paper has been temporarily withdrawn by the author because there are errors in it that require further study.

This paper has been withdrawn by author due to an error in the proof.

In this paper we investigate the efficiency of quantum cloning of $N$ identical mixed qubits. We employ a recently introduced measure of distinguishability of quantum states called quantum Chernoff bound. We evaluate the quantum Chernoff…

This paper has been removed by the author due to a misstatement in Theorem 1 and a gap in its proof. A corrected and largely extended successor (a joint work with Thomas Bauer and Tomasz Szemberg) can be found under math.AG/0312211,

We consider the problem of detecting the true quantum state among r possible ones, based on measurements performed on n of copies of a finite dimensional quantum system. It is known that the exponent for the rate of decrease of the averaged…

This paper has been withdrawn by the author due to a critical error in the proof of Theorem A pointed out by Burkhard Wilking.

This paper is withdrawn. See quant-ph/9806031 for a discussion.

This paper has been withdrawn by the author due to an error.

This paper has been withdrawn by the authors, due to the discovery of paper 0201028 which predates it and contains most of it's results.

This paper has been withdrawn by the author due to extremely unscientific errors.

This paper has been withdrawn by the author due to an error in the proof of Theorem 1.
