One Hundred Years of Quantum Physics
... by a novice – Niels Bohr. In 1913 Bohr proposed the radical hypothesis that electrons in an atom exist only in certain stationary states, including a ground state. Electrons change their energy by “jumping” between the stationary states, emitting light whose wavelength depends on the energy differen ...

... the strange and counter-intuitive world of quantum mechanics – to speed computation. Rather than store information as 0s or 1s as conventional computers do, a quantum computer uses qubits – which can be 1 or 0 or both at the same time. This “quantum superposition” enables quantum computers to consid ...

... in quantum optics is called “dark state”. We note that this is a dissipative, albeit deterministic preparation of the state |ψi. On a single-particle level the concept of preparing a pure state by dissipation is well-known from optical pumping of internal electronic states of atoms and laser cooling ...

... It is in the equations that the problem of measurement is most starkly seen. The state ψ in non-relativistic quantum mechanics is a function on the configuration space of a system (or one isomorphic to it, like momentum space). A point in this space specifies the positions of all the particles compr ...
