We laser-cool single beryllium ions in a Paul trap to the ground (n equals 0) quantum harmonic oscillator state with greater than 90% probability. From this starting point, we can put the atom into various quantum states of motion by application of optical and rf electric fields. Some of these states resemble classical states (the coherent states), while others are intrinsically quantum, such as number states or squeezed states. We have created entangled position and spin superposition states…

### Decoherence of quantum superpositions through coupling to engineered reservoirs

- PhysicsNature
- 2000

Decoherence is induced by coupling the atom to engineered reservoirs, in which the coupling and state of the environment are controllable, and the decoherence rate scales with the square of a quantity describing the amplitude of the superposition state.

The Leggett-Garg inequality can be violated through a genuine negative result measurement, thereby repudiating the everyday notion of macrorealism and opening up potentially the simplest way for testing whether various recently engineered and sought after macroscopic oscillators are indeed bona fide nonclassical objects.
