... but such states are hard to create3–7. Here we demonstrate the controlled generation of multi-photon Fock states in a solid-state system. We use a superconducting phase qubit8, which is a close approximation to a two-level spin system, coupled to a microwave resonator, which acts as a harmonic oscil ...

... chips rapidly decreases. Once the size of individual elements reach a certain critical level, their behavior and properties are no longer governed by classical physics, but rather by quantum mechanics. Another motivation was put forward by Richard P. Feynman [Feynman, 1982], who was among the first ...
