Device-independent quantum key distribution based on Bell inequalities with more than two inputs and two outputs
Junior R. Gonzales-Ureta, Ana Predojević, Adán Cabello
Device-independent quantum key distribution (DI-QKD) offers the strongest form of security against eavesdroppers bounded by the laws of quantum mechanics. However, a practical impl…
Technological implementation of a photonic Bier-Glass cavity
Jonathan Jurkat, Magdalena Moczała-Dusanowska, Martin Arentoft Jacobsen +5
In this paper, we introduce a novel quantum photonic device, which we term photonic Bier-Glass cavity. We discuss its fabrication and functionality, which is based on the coupling…
Effect of source statistics on utilizing photon entanglement in quantum key distribution
Radim Hošák, Ivo Straka, Ana Predojević +2
A workflow for evaluation of entanglement source quality is proposed. Based on quantum state density matrices obtained from theoretical models and experimental data, we make an est…
Opto-Mechanical Tuning of the Polarization Properties of Micropillar Cavity Systems with embedded Quantum Dots
Stefan Gerhardt, Magdalena Moczała-Dusanowska, Łukasz Dusanowski +7
Strain tuning emerged as an appealing tool to tune fundamental optical properties of solid state quantum emitters. In particular, the wavelength and fine structure of quantum dot s…
Polarization dependent light-matter coupling and highly indistinguishable resonance fluorescence photons from quantum dot-micropillar cavities with elliptical cross-section
Stefan Gerhardt, Michael Deppisch, Simon Betzold +5
We study the optical properties of coupled quantum dot-microcavity systems with elliptical cross section. First, we develop an analytic model that describes the spectrum of the cav…
Interfacing a quantum dot with a spontaneous parametric down-conversion source
Tobias Huber, Maximilian Prilmüller, Michael Sehner +3
Quantum networks require interfacing stationary and flying qubits. These flying qubits are usually nonclassical states of light. Here we consider two of the leading source technolo…
Time-bin Entanglement from Quantum Dots
Gregor Weihs, Tobias Huber, Ana Predojević
The desire to have a source of single entangled photon pairs can be satisfied using single quantum dots as emitters. However, we are not bound to pursue only polarization entanglem…
Optimal excitation conditions for indistinguishable photons from quantum dots
Tobias Huber, Ana Predojević, Daniel Föger +2
In this letter, we present a detailed, all optical study of the influence of different excitation schemes on the indistinguishability of single photons from a single InAs quantum d…
Coherence and degree of time-bin entanglement from quantum dots
Tobias Huber, Laurin Ostermann, Maximilian Prilmüller +4
We report on the generation of time-bin entangled photon pairs from a semiconductor quantum dot via pulsed resonant biexciton generation. Based on theoretical modeling we optimized…
