Quantum coding.
A theorem is proven for quantum information theory that is analogous to the noiseless coding theorem of classical information theory. In the quantum result, the von Neumann entropy S of the density operator describing an ensemble of pure quantum signal states is equal to the number of spin-1/2 systems (quantum bits or \qubits") necessary to represent the signal faithfully. The theorem holds whe...
متن کاملStationary quantum source coding
In this paper the quantum version of the source coding theorem is obtained for a completely ergodic source. This result extends Schumacher’s quantum noiseless coding theorem for memoryless sources. The control of the memory effects requires some earlier results of Hiai and Petz on high probability subspaces. Our result is equivalently considered as a compression theorem for noiseless stationary...
متن کاملIndeterminate-length quantum coding
The quantum analogues of classical variable-length codes are indeterminatelength quantum codes, in which codewords may exist in superpositions of different lengths. This paper explores some of their properties. The length observable for such codes is governed by a quantum version of the KraftMcMillan inequality. Indeterminate-length quantum codes also provide an alternate approach to quantum da...
متن کاملExtended Quantum Color Coding
The quantum color coding scheme proposed by Korff and Kempe [1] is easily extended so that the color coding quantum system is allowed to be entangled with an extra auxiliary quantum system. It is shown that in the extended scheme we need only ∼ 2 √ N quantum colors to order N objects in large N limit, whereas ∼ N/e quantum colors are required in the original non-extended version. The maximum su...
متن کاملQuantum Convolutional Coding
We show how to protect a stream of quantum information from decoherence induced by a noisy quantum communication channel. We exploit preshared entanglement and a convolutional coding structure to develop a theory of entanglementassisted quantum convolutional coding. Our construction produces a Calderbank-Shor-Steane (CSS) entanglement-assisted quantum convolutional code from two arbitrary class...
