Twisted photons can be used as alphabets to encode information beyond one bit per single
photon. This ability offers great potential for quantum information tasks, as well as for the …

In recent years, there has been a rising interest in high‐dimensional quantum states and
their impact on quantum communication. Indeed, the availability of an enlarged Hilbert …

There are many excellent books on quantum theory from which one can learn to compute
energy levels, transition rates, cross sections, etc. The theoretical rules given in these books …

An algorithmic proof that any discrete finite-dimensional unitary operator can be constructed
in the laboratory using optical devices is given. Our recursive algorithm factorizes any N× N …

This book compares various approaches to the interpretation of quantum mechanics, in
particular those which are related to the key words" the Copenhagen interpretation"," the …

A review is presented of light-intensity interference experiments demonstrating the
inadequacy of the classical concept of a priori properties of quantum objects (Bell's …

Tests of local realism versus quantum mechanics based on Bell's inequality employ two
entangled qubits. We investigate the general case of two entangled quantum systems …

Higgs boson decays produce pairs of W bosons in a maximally entangled state, the spins of
which can be expected to violate Bell inequalities. We show that the spin density matrix of …

For any nonfactorable state of two quantum systems, it is possible to find pairs of
observables whose correlations violate Bell's inequality. In the case of two particles of spin j …

Local realism implies constraints on the statistics of two physically separated systems. These
constraints, known collectively as Bell inequalities, can be violated by quantum mechanics …
