... At the first level, there are two boxes. Call them L and R. Alice inputs a1 ⊕ a2 into the L box, and a3 ⊕ a4 into the R box. Bob inputs b1 into both boxes (the input to one of these boxes is going to be irrelevant, depending on what bit Bob aims to guess). At the second level, they use one box. Alic ...

Dynamics of exciton dissociation in donor- acceptor polymer heterojunctions
... The process from the absorption of photons to the extraction of free charge carriers is a multi-step process: (i) the absorption of a photon, usually by the donor, generates an exciton, (ii) the exciton diffuses to the donor/acceptor (D/A) interface and dissociates into a charge transfer (CT) state, ...

Entanglement and state characterisation from two-photon interference
... We have seen that two-photon interference has been widely studied in the last thirty years and that it has been used for different purposes depending on the situation: for example, it is a way to prove the indistinguishability of photons or to highlight the metrological advantage given by NOON state ...

Quantum electrodynamics
In particle physics, quantum electrodynamics (QED) is the relativistic quantum field theory of electrodynamics. In essence, it describes how light and matter interact and is the first theory where full agreement between quantum mechanics and special relativity is achieved. QED mathematically describes all phenomena involving electrically charged particles interacting by means of exchange of photons and represents the quantum counterpart of classical electromagnetism giving a complete account of matter and light interaction.In technical terms, QED can be described as a perturbation theory of the electromagnetic quantum vacuum. Richard Feynman called it ""the jewel of physics"" for its extremely accurate predictions of quantities like the anomalous magnetic moment of the electron and the Lamb shift of the energy levels of hydrogen.
