Surpassing the no-cloning limit with a heralded hybrid linear amplifier for coherent states

Cloning an unknown quantum state is challenging and the limit on the quality of clones is set by the no-cloning theorem. Here, the authors demonstrated the surpassing of such a limit using an effective quantum cloner based on a hybrid probabilistic-deterministic linear amplifier.
