Abstract

It was believed until recently that quantum key distribution with continuous variables would be restricted to losses below 3 dB due to the beam splitting attack. We show that post-selection allows to overcome this limitation.

Continuous variable quantum key distribution: Beating the 3 DB loss limit

Norbert Lütkenhaus, Christine Silberhorn, Gerd Leuchs +1 more

We demonstrate that quantum key distribution systems based on continuous variable implementations can operate beyond the apparent 3 dB loss limit that is implied by the beam splitting attack. Here we discuss the information-theoretical background and explain the difference between our approach and that by Grosshans and Grangier.

Continuous Variable Quantum Cryptography: Beating the 3 dB Loss Limit

Christine Silberhorn, Timothy C. Ralph, Norbert Lütkenhaus +1 more

We demonstrate that secure quantum key distribution systems based on continuous variable implementations can operate beyond the apparent 3 dB loss limit that is implied by the beam splitting attack. The loss limit was established for standard minimum uncertainty states such as coherent states. We show that, by an appropriate postselection mechanism, we can enter a region where Eve's knowledge on Alice's key falls behind the information shared between Alice and Bob, even in the presence of substantial losses.

Security of continuous-variable quantum cryptography using coherent states: Decline of postselection advantage

Ryo Namiki, Takuya Hirano

We investigate the security of continuous-variable (CV) quantum key distribution (QKD) using coherent states in the presence of quadrature excess noise. We consider an eavesdropping attack that uses a linear amplifier and a beam splitter. This attack makes a link between the beam-splitting attack and the intercept-resend attack (classical teleportation attack). We also show how postselection loses its efficiency in a realistic channel.
