Photonic Violation of Wigner's Inequality
Maximilian Rottensteiner, Dorian Schiffer, Tobias Pausch +2
Teaching quantum mechanics is challenging, not least because the theory often conflicts with our classical worldview. Quantum correlations in particular are notoriously counter-int…
Genuine Hybrid Number-Polarization Entanglement
Dorian Schiffer, Marcus Huber, Elizabeth Agudelo
Entanglement is a key resource for fundamental tests of physics and emerging quantum technologies. In quantum optics, two perspectives on entanglement coexist. In the continuous-va…
Radio-Frequency Side-Channel Analysis of a Trapped-Ion Quantum Computer
Giorgio Grigolo, Dorian Schiffer, Lukas Gerster +2
Analogously to classical computers, quantum processors exhibit side channels that may give attackers access to potentially proprietary algorithms. We identify and exploit a previou…
Bright Source of High-Dimensional Temporal Entanglement
Dorian Schiffer, Robert Kindler, Alexandra Bergmayr-Mann +5
High-dimensional entanglement is considered to hold great potential for quantum key distribution (QKD) in high-loss and -noise scenarios. To harness its robustness, we construct a…
