Quantum dissection of a covalent bond with the entanglement
... The values of λ for HF wave functions are listed in Table 1. We see that the perfectly localised groups of four (0, 0, 1, 1) and delocalised groups of two (1/2, 1/2) are the only grouping of electrons needed to describe most of the molecules. However, in the case of C2 and Be2 , there are groupings ...

Equivalence of Topological Codes and Fast Decoding
... that takes one code and maps it to the other, and vice versa. Our main result is the following [1, 4]: Theorem 1 Every 2D TSC is locally equivalent to a finite number of copies of KTC. To define precisely what we mean by local, consider an operator P acting on some qubits contained within a region o ...

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.
