Finite Size Analysis of Decoy-State BB84 with Advantage Distillation
Jonas Treplin, Philipp KleinpaÃ, Davide Orsucci
Advantage Distillation (AD) is a classical post-processing technique that enhances Quantum Key Distribution (QKD) protocols by increasing the maximum acceptable Quantum Bit Error R…
Simulation of satellite and optical link dynamics in a quantum repeater constellation
Jaspar Meister, Philipp KleinpaÃ, Davide Orsucci
Quantum repeaters and satellite-based optical links are complementary technological approaches to overcome the exponential photon loss in optical fibers and thus allow quantum comm…
Frequency-Resolved Simulations of Highly Entangled Biphoton States: Beyond the Single-Pair Approximation. II. Application to Entanglement-based Quantum Key Distribution
Philipp KleinpaÃ, Thomas Walther, Erik Fitzke
We present time- and frequency-resolved simulations of quantum key distribution~(QKD) systems employing highly entangled biphoton quantum states. Our simulations are based on expan…
Frequency-Resolved Simulations of Highly Entangled Biphoton States: Beyond the Single-Pair Approximation. I. Theory
Philipp KleinpaÃ, Thomas Walther, Erik Fitzke
We discuss an expansion of the detection probabilities of biphoton states in terms of increasing orders of the joint spectral amplitude. The expansion enables efficient time- or fr…
