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…
Topological order in symmetric blockade structures
Tobias F. Maier, Hans Peter Büchler, Nicolai Lang
The bottom-up design of strongly interacting quantum materials with prescribed ground state properties is a highly nontrivial task, especially if only simple constituents with real…
Quantum doubles in symmetric blockade structures
Hans Peter Büchler, Tobias F. Maier, Simon Fell +1
Exactly solvable models of topologically ordered phases with non-abelian anyons typically require complicated many-body interactions which do not naturally appear in nature. This m…
Homogeneous Magnetic Flux in Rydberg Lattices
Joseph Eix, Rukmani Bai, Thierry Lahaye +3
We present a method for generating homogeneous and tunable magnetic flux for bosonic particles in a lattice using Rydberg atoms. Our setup relies on Rydberg excitations hopping thr…
