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…
Suppressing crosstalk for Rydberg quantum gates
Gina Warttmann, Florian Meinert, Hans Peter Büchler +1
We present a method to suppress crosstalk from implementing controlled-Z gates via local addressing in neutral atom quantum computers. In these systems, a fraction of the laser lig…
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…
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…
Coherent Control of the Fine-Structure Qubit in a Single Alkaline-Earth Atom
Govind Unnikrishnan, Philipp Ilzhöfer, Achim Scholz +10
We report on the first realization of a novel neutral atom qubit encoded in the metastable fine-structure states and of single Sr atoms trapped…
