Quantum key distribution without reference frame alignment: Exploiting photon orbital angular momentum
Federico M. Spedalieri
We present a new implementation of the BB84 quantum key distribution protocol that employs a -dimensional Hilbert space spanned by spatial modes of the propagating beam that hav…
Exploiting the quantum Zeno effect to beat photon loss in linear optical quantum information processors
Federico M. Spedalieri, Hwang Lee, Marian Florescu +3
We devise a new technique to enhance transmission of quantum information through linear optical quantum information processors. The idea is based on applying the Quantum Zeno effec…
Detecting multipartite entanglement
Andrew C. Doherty, Pablo A. Parrilo, Federico M. Spedalieri
We discuss the problem of determining whether the state of several quantum mechanical subsystems is entangled. As in previous work on two subsystems we introduce a procedure for ch…
