... We implemented a two ion entangling gate to produce Bell states with the highest fidelity so far (99.3%) at the start of the project. The gate has also been used on thermal ions, i.e. without ground-state cooling. This result is of key importance for scalable quantum computing, as this generally req ...

... within a distance called the Compton wavelength of order = ~/mc (forgetting the factor 2), the probability to detect a pair of particle anti-particle becomes large. Thus, the notion of a single particle within a volume becomes a non-sense. The formalism must be able to describe states of any number ...

Instanton

An instanton (or pseudoparticle) is a notion appearing in theoretical and mathematical physics. An instanton is a classical solution to equations of motion with a finite, non-zero action, either in quantum mechanics or in quantum field theory. More precisely, it is a solution to the equations of motion of the classical field theory on a Euclidean spacetime.
