In information processing, as in physics, our classical world view provides an incomplete
approximation to an underlying quantum reality. Quantum effects like interference and …

Multiphoton interference reveals strictly nonclassical phenomena. Its applications range
from fundamental tests of quantum mechanics to photonic quantum information processing …

Развитие квантовой оптики конца ХХ века стремительно заставляет нас ì не только
ученых, работающих в области квантовой физики, но и людей далеких от этой области …

A digital computer is generally believed to be an efficient universal computing device; that is,
it is believed to be able to simulate any physical computing device with an increase in …

We show that a set of gates that consists of all one-bit quantum gates [U (2)] and the two-bit
exclusive-O R gate [that maps Boolean values (x, y) to (x, x⊕ y)] is universal in the sense …

The negatively charged silicon vacancy (SiV) color center in diamond has recently proven its
suitability for bright and stable single photon emission. However, its electronic structure so …

A quantum computer can be implemented with cold ions confined in a linear trap and
interacting with laser beams. Quantum gates involving any pair, triplet, or subset of ions can …

We report on a high-intensity source of polarization-entangled photon pairs with high
momentum definition. Type-II noncollinear phase matching in parametric down conversion …

A quantum error-correcting code is defined to be a unitary map** (encoding) of k qubits
(two-state quantum systems) into a subspace of the quantum state space of n qubits such …
