Abstract We introduce and experimentally demonstrate the idea of noiseless linear amplification of a harmonic oscillator. While deterministic amplification of this kind violates the quantum no-cloning theorem, nondeterministic heralded amplification is possible. We demonstrate an experimental circuit to realize this concept, and use it for a simple distillation of field entanglement. The concept has application to the distillation of continuous-variables EPR entanglement and quantum communications tasks.
