Abstract :
Summary form only given. A one-electron cyclotron oscillator is cooled to thermal equilibrium at temperatures between 70 mK and 4.2 K - the first time that an isolated elementary particle has been cooled below 4.2 K. Continuous quantum non-demolition (QND) measurements of the electron cyclotron energy reveal the equilibrium oscillator in a quantum Fock state, with occasional and abrupt quantum jumps to adjacent Fock states, stimulated by blackbody photons in the cavity.
