Ion trap on borosilicate substrate with integrated femtosecond-laser-written waveguide
Jakob Wahl, Alexander Zesar, Philipp Hurdax +9
We present an ion-trap platform on borosilicate glass with an integrated femtosecond-laser-written waveguide for on-chip light delivery. The optical layer is physically separated f…
Holographic quantum codes with trapped ions
Alex Steiner, Gerard Anglès Munné, Robert Freund +9
Holography is a central concept at the intersection of gravity, condensed matter theory, and quantum information, linking the interior bulk of a system to its boundary. A model rea…
Genuine Multipartite Entanglement between Logical Qubits via Cross-Code Lattice Surgery
Alex Steiner, Tomasz Andrzejewski, Phila Rembold +8
Universal quantum computers are expected to generate arbitrary complex quantum states of logical qubits encoded in many physical qubits. This capability hinges on a fault-tolerantl…
Clifford Volume and Free Fermion Volume: Complementary Scalable Benchmarks for Quantum Computers
Attila Portik, Orsolya Kálmán, Thomas Monz +1
As quantum computing advances toward the late-NISQ and early fault-tolerant eras, scalable and platform-independent benchmarks are essential for quantifying computational capacity…
Experimental measurement and a physical interpretation of quantum shadow enumerators
Daniel Miller, Kyano Levi, Lukas Postler +18
Throughout its history, the theory of quantum error correction has heavily benefited from translating classical concepts into the quantum setting. In particular, classical notions…
Learning symmetry-protected topological order from trapped-ion experiments
Nicolas Sadoune, Ivan Pogorelov, Claire L. Edmunds +6
Classical machine learning has proven remarkably useful in post-processing quantum data, yet typical learning algorithms often require prior training to be effective. In this work,…
