All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

Quantum information is a rapidly advancing area of interdisciplinary research. It may lead to
real-world applications for communication and computation unavailable without the …

An unknown quantum state‖ φ> can be disassembled into, then later reconstructed from,
purely classical information and purely nonclassical Einstein-Podolsky-Rosen (EPR) …

Practical application of the generalized Bell's theorem in the so-called key distribution
process in cryptography is reported. The proposed scheme is based on the Bohm's version …

Ekert has described a cryptographic scheme in which Einstein-Podolsky-Rosen (EPR) pairs
of particles are used to generate identical random numbers in remote places, while Bell's …

Over the past few decades, significant progress has been made in quantum information
technology, from theoretical studies to experimental demonstrations. Revolutionary quantum …

What entanglement is present in naturally occurring physical systems at thermal
equilibrium? Most such systems are intractable and it is desirable to study simple but …

The quantum-mechanical uncertainty in the position of a particle or the time of its emission is
shown to produce observable effects that are inconsistent with any local hidden-variable …

We develop a novel approach to Bell inequalities based on a constraint that the correlations
exhibited by local variable theories must satisfy. This is used to construct a family of Bell …

It is shown that it is possible to demonstrate nonlocality for two particles without using
inequalities for all entangled states except maximally entangled states such as the singlet …
