Multiqubit Rydberg Gates for Quantum Error Correction
David F. Locher, Josias Old, Katharina Brechtelsbauer +4
Multiqubit gates that involve three or more qubits are usually thought to be of little significance for fault-tolerant quantum error correction because single gate faults can lead…

Measurement-free quantum error correction optimized for biased noise
Katharina Brechtelsbauer, Friederike Butt, David F. Locher +4
In this paper, we derive optimized measurement-free protocols for quantum error correction and the implementation of a universal gate set optimized for an error model that is noise…

Bosonic Quantum Error Correction with Neutral Atoms in Optical Dipole Traps
Leon H. Bohnmann, David F. Locher, Johannes Zeiher +1
Bosonic quantum error correction codes encode logical qubits in the Hilbert space of one or multiple harmonic oscillators. A prominent class of bosonic codes is that of Gottesman-K…
