Demonstrating Record Fidelity for the Quantum Fourier Transform
Philipp Aumann, Michael Fellner, David Alber +6
We demonstrate the Parity Architecture on quantum hardware, using the quantum Fourier transform (QFT) as a benchmark. As a result, a record performance in both fidelity and qubit c…
Spin Model for Quantum Annealing with Kerr Parametric Oscillators
Leo Stenzel, Roeland ter Hoeven, Ryoji Miyazaki +3
Coherent states offer a promising path for near-term quantum computing due to their inherent protection against bit-flip noise. However, their large photon numbers can be challengi…
Optimal Decoder for the Error Correcting Parity Code
Konstantin Tiurev, Christophe Goeller, Leo Stenzel +4
We present a two-step decoder for the parity code and evaluate its performance in code-capacity and faulty-measurement settings. For noiseless measurements, we find that the decodi…
Quantum phases and topological properties of interacting fermions in one-dimensional superlattices
Leo Stenzel, Andrew L. C. Hayward, Claudius Hubig +2
The realization of artificial gauge fields in ultracold atomic gases has opened up a path towards experimental studies of topological insulators and, as an ultimate goal, topologic…
