Composable security proof for continuous-variable quantum key distribution with coherent states [PDF]
, 2014 We give the first composable security proof for continuous-variable quantum key distribution with coherent states against collective attacks. Crucially, in the limit of large blocks the secret key rate converges to the usual value computed from the ...

Fault tolerant quantum key distribution protocol with collective random unitary noise [PDF]
, 2004 We propose an easy implementable prepare-and-measure protocol for robust quantum key distribution with photon polarization. The protocol is fault tolerant against collective random unitary channel noise.

A Long Shadow of World War II: Development of the National Security Concept in the United States
Вестник Московского Университета. Серия XXV: Международные отношения и мировая политика, 2020 In recent years, the history of World War II has transformed into a battlefield in its own right in the ‘war of memory’. Besides the clear fact that the current attempts to revise the results of this war reflect the contemporary international tensions, yet

Continuous-variable quantum cryptography with discrete alphabets: Composable security under collective Gaussian attacks [PDF]
Physical Review Research, 2019 We consider continuous-variable quantum key distribution with discrete-alphabet encodings. In particular, we study protocols where information is encoded in the phase of displaced coherent (or thermal) states, even though the results can be directly ...

Collective attacks and unconditional security in continuous variable quantum key distribution
, 2004 We present here an information theoretic study of Gaussian collective attacks on the continuous variable key distribution protocols based on Gaussian modulation of coherent states.
