Quantum XYZ Stabilizer Codes
Alessio Baldelli, Davide Orsucci, Francisco Lázaro +1
Stabilizer codes are often constructed within the Calderbank--Shor--Steane (CSS) framework, where two mutually orthogonal binary classical codes define and -type stabilizer…
Finite Size Analysis of Decoy-State BB84 with Advantage Distillation
Jonas Treplin, Philipp Kleinpaß, 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…
Optimization of Information Reconciliation for Decoy-State Quantum Key Distribution over a Satellite Downlink Channel
Thomas Scarinzi, Davide Orsucci, Marco Ferrari +1
Quantum key distribution (QKD) is a cryptographic solution that leverages the properties of quantum mechanics to be resistant and secure even against an attacker with unlimited com…
Simulation of satellite and optical link dynamics in a quantum repeater constellation
Jaspar Meister, Philipp Kleinpaß, 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…
Real-time antiproton annihilation vertexing with sub-micron resolution
M. Berghold, D. Orsucci, F. Guatieri +63
The primary goal of the AEgIS experiment is to precisely measure the free fall of antihydrogen within Earth's gravitational field. To this end, a cold ~50K antihydrogen beam has to…
Assessment of practical satellite quantum key distribution architectures for current and near-future missions
Davide Orsucci, Philipp Kleinpaß, Jaspar Meister +5
Quantum key distribution (QKD) allows the generation of cryptographic keys beyond the computational hardness paradigm and is befitting for secure data transmission requiring long-t…
International time transfer between precise timing facilities secured with a quantum key distribution network
Francesco Picciariello, Francesco Vedovato, Davide Orsucci +14
Global Navigation Satellite Systems (GNSSs), such as GPS and Galileo, provide precise time and space coordinates globally and constitute part of the critical infrastructure of mode…
Classical product code constructions for quantum Calderbank-Shor-Steane codes
Dimiter Ostrev, Davide Orsucci, Francisco Lázaro +1
Several notions of code products are known in quantum error correction, such as hyper-graph products, homological products, lifted products, balanced products, to name a few. In th…

Quantum algorithms for solving the Quantum Linear System (QLS) problem are among the most investigated quantum algorithms of recent times, with potential applications including the…
What is the minimum CHSH score certifying that a state resembles the singlet?
Xavier Valcarce, Pavel Sekatski, Davide Orsucci +3
A quantum state can be characterized from the violation of a Bell inequality. The well-known CHSH inequality for example can be used to quantify the fidelity (up to local isometrie…
How post-selection affects device-independent claims under the fair sampling assumption
Davide Orsucci, Jean-Daniel Bancal, Nicolas Sangouard +1
Device-independent certifications employ Bell tests to guarantee the proper functioning of an apparatus from the sole knowledge of observed measurement statistics, i.e. without ass…

Nicolai Friis, Davide Orsucci, Michalis Skotiniotis +4
Quantum metrology offers a quadratic advantage over classical approaches to parameter estimation problems by utilizing entanglement and nonclassicality. However, the hurdle of actu…
Estimation of coherent error sources from stabilizer measurements
Davide Orsucci, Markus Tiersch, Hans J. Briegel
In the context of measurement-based quantum computation a way of maintaining the coherence of a graph state is to measure its stabilizer operators. Aside from performing quantum er…
