Peter Heuer - Quantum Cryptography Using Single and Entangled
... Bob in their original state, leaving no sign of her intervention. A stream of photons that are truly spatially separated is said to be antibunched. An attenuated laser beam contains bunched photons and is therefore insufficient for secure quantum communication. True single photon sources are created ...

Theory of quantum state control with solid-state qubits Research supervisor
... The potential to exploit quantum-mechanics in technology, from sensors to computers, is vast. Essential for these developments, however, is the ability to take a quantum system with a few discrete states, such as an exciton in a quantum dot or impurity state in a crystal, and control its wavefunctio ...

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.
