Quantum Communications Based on Quantum Hashing
CoRR, 2013 In this paper we consider an application of the recently proposed quantum hashing technique for computing Boolean functions in the quantum communication model. The combination of binary functions on non-binary quantum hash function is done via polynomial presentation, which we have called a characteristic of a Boolean function.

Surpassing the no-cloning limit with a heralded hybrid linear amplifier for coherent states
Nature Communications, 2016 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 ...
