All information in quantum systems is, notwithstanding Bell's theorem, localized. Measuring or otherwise interacting with a quantum system S has no effect on distant systems from which S is dynamically isolated, even if they are entangled with S. Using the Heisenberg picture to analyse quantum information processing makes this locality explicit, and reveals that under some circumstances (in particular, in Einstein–Podolsky–Rosen experiments and in quantum teleportation), quantum information is… Expand

Quantum information does not exist
It is demonstrated that conceptually puzzling phenomena in quantum information theory, such as dense coding, teleportation, and Schumacher coding, all of which are cited as evidence that a new concept of information is required, do not have to be regarded as such. Expand
Topics on Quantum Locality
It has been 20 years since Deutsch and Hayden demonstrated that quantum systems can be completely described locally -- notwithstanding Bell's theorem. More recently, Raymond-Robichaud proposedExpand
Entanglement Theory and a q Analogue Entangled State
Entangled state and entanglement theory in the quantum information are pre- sented. A q analogue entangled state is flrst put forward in this paper. It exhibits a much richer structure than ordinaryExpand
Quantum Mechanics and Nonlocality: In Search of Instructive Description
A problem with an instructive description of measurement process for sufficiently separated entangled quantum systems is well known. More precise and crafty experiments together with newExpand
Developing the Deutsch?Hayden approach to quantum mechanics
The formalism of Deutsch and Hayden is a useful tool for describing quantum mechanics explicitly as local and unitary, and therefore quantum information theory as concerning a 'flow' of informationExpand
Quantum information does exist
This paper extends Timpson's framework for interpreting Shannon information theory to the quantum context and argues that entanglement fidelity is advocated as the appropriate success criterion for the reproduction of quantum information. Expand
Quantum Nonlocality: Not Eliminated by the Heisenberg Picture
It is argued that the Heisenberg picture of standard quantum mechanics does not save Einstein locality as claimed in Deutsch and Hayden (Proc. R. Soc. Lond. A 456, 1759–1774, 2000). In particular,Expand
Channel kets, entangled states, and the location of quantum information (16 pages)
The well-known duality relating entangled states and noisy quantum channels is expressed in terms of a channel ket, a pure state on a suitable tripartite system, which functions as a pre-probabilityExpand
Entropy Production in Quantum is Different
This review article deals with the problem of time for one of the central quantities in quantum information theory: entropy, and shows that entropy can flow internally between subsystems; however, it is shown that this flow is not limited to physical correlations as the literature suggest. Expand
Explaining Information Transfer in Quantum Teleportation
In this paper I introduce a new species of teleportation which I use to evaluate three explanations of information transfer in quantum teleportation. I will argue that two explanations fail toExpand


Conditional Quantum Dynamics and Logic Gates.
A simple quantum logic gate, the quantum controlled-NOT, is described, and two possible physical realizations of the gate are discussed, one based on Ramsey atomic interferometry and the other on the selective driving of optical resonances of two subsystems undergoing a dipole-dipole interaction.

Some general foundational issues of quantum mechanics are considered and are related to aspects of quantum computation. The importance of quantum entanglement and quantum information is discussed andExpand
Pointer Basis of Quantum Apparatus: Into What Mixture Does the Wave Packet Collapse?
The form of the interaction Hamiltonian between the apparatus and its environment is sufficient to determine which observable of the measured quantum system can be considered "recorded" by theExpand
Teleporting an unknown quantum state via dual classical and Einstein-Podolsky-Rosen channels.
An unknown quantum state \ensuremath{\Vert}\ensuremath{\varphi}〉 can be disassembled into, then later reconstructed from, purely classical information and purely nonclassical Einstein-Podolsky-RosenExpand
A single quantum cannot be cloned
If a photon of definite polarization encounters an excited atom, there is typically some nonvanishing probability that the atom will emit a second photon by stimulated emission. Such a photon isExpand
Quantum Information Theory
The fundamentals of the field, source coding, quantum error-correcting codes, capacities of quantum channels, measures of entanglement and quantum cryptography are discussed. Expand
Teleportation with Bright Squeezed Light
We examine the teleportation of continuous quantum variables from a small signal communication point of view. We show that mixed bright squeezed beams can provide the entanglement required forExpand

Experimental Test of Bell's Inequalities Using Time- Varying Analyzers
Correlations of linear polarizations of pairs of photons have been measured with time-varying analyzers. The analyzer in each leg of the apparatus is an acousto-optical switch followed by two linearExpand
