Entanglement is precious, allowing us to perform all kinds of quantum tricks. But it is easily buried under technical noise. Two experiments show how to distil the 'good parts' from a data stream and recover high-quality entanglement.

Two independent experiments demonstrate that quantum entanglement that has been lost in decoherence processes can be recovered. For the first time such ?entanglement distillation? has been achieved for states of light that are entangled in continuous variables, which should help to increase the distance over which quantum information can be distributed.
