A Novel Protocol-Authentication Algorithm Ruling Out a Man-in-the-Middle Attack in Quantum Cryptography
M. Peev, M. Nölle, O. Maurhardt +6
In this work we review the security vulnerability of Quantum Cryptography with respect to "man-in-the-middle attacks" and the standard authentication methods applied to counteract…
Aperiodic quantum oscillations of particle-hole asymmetric Dirac cones
E. Tisserond, J. N. Fuchs, M. O. Goerbig +9
We report experimental measurements and theoretical analysis of Shubnikov-de Haas (SdH) oscillations in a Dirac cone system: the a-(BEDT-TTF)2I3 organic metal under hydrostatic pre…
Practical Quantum Key Distribution with Polarization-Entangled Photons
A. Poppe, A. Fedrizzi, T. Loruenser +9
We present an entangled-state quantum cryptography system that operated for the first time in a real world application scenario. The full key generation protocol was performed in r…
Quantum Hall effect in multilayered massless Dirac fermion systems with tilted cones
N. Tajima, T. Yamauchi, T. Yamaguchi +6
We report the first observation of Shubnikov-de Haas (SdH) oscillations and quantized Hall resistance in the multilayered massless Dirac fermion system -(BEDT-TTF)I wit…
Size effects on supercooling phenomena in strongly correlated electron systems: IrTe and -(BEDT-TTF)RbZn(SCN)
H. Oike, M. Suda, M. Kamitani +5
We report that the sample miniaturization of first-order-phase-transition bulk systems causes a greater degree of supercooling. From a theoretical perspective, the size effects can…
Quantum Phase Transition in Organic Massless Dirac Fermion System -(BEDT-TTF)I under pressure
Y. Unozawa, Y. Kawasugi, M. Suda +6
We investigate the effect of strong electronic correlation on the massless Dirac fermion system, -(BEDT-TTF)I, under pressure. In this organic salt, one can control the…
Decoherence, fluctuations and Wigner function in neutron optics
P. Facchi, A. Mariano, S. Pascazio +1
We analyze the coherence properties of neutron wave packets, after they have interacted with a phase shifter undergoing different kinds of statistical fluctuations. We give a quant…
New intensity and visibility aspects of a double loop neutron interferometer
M. Suda, H. Rauch, M. Peev
Various phase shifters and absorbers can be put into the arms of a double loop neutron interferometer. The mean intensity levels of the forward and diffracted beams behind an empty…
