Reducing hardware requirements for entanglement distribution via joint hardware-protocol optimization

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Adrià Labay-Mora, Francisco Ferreira da Silva, Stephanie Wehner, , | Summary: We conduct a numerical investigation of fiber-based entanglement distribution over distances of up to 1600km using a chain of processing-node quantum repeaters. We determine minimal hardware requirements while simultaneously optimizing over protocols for entanglement generation and […]

Coherent spin dynamics between electron and nucleus within a single atom

Kavli Affiliate: Sander Otte | First 5 Authors: Lukas M. Veldman, Evert W. Stolte, Mark P. Canavan, Rik Broekhoven, Philip Willke | Summary: The nuclear spin, being much more isolated from the environment than its electronic counterpart, enables quantum experiments with prolonged coherence times and presents a gateway towards uncovering the intricate dynamics within an […]

Single-electron occupation in quantum dot arrays at selectable plunger gate voltage

Kavli Affiliate: Menno Veldhorst | First 5 Authors: Marcel Meyer, Corentin Déprez, Ilja N. Meijer, Florian K. Unseld, Saurabh Karwal | Summary: The small footprint of semiconductor qubits is favourable for scalable quantum computing. However, their size also makes them sensitive to their local environment and variations in gate structure. Currently, each device requires tailored […]

A Control Architecture for Entanglement Generation Switches in Quantum Networks

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Scarlett Gauthier, Gayane Vardoyan, Stephanie Wehner, , | Summary: Entanglement between quantum network nodes is often produced using intermediary devices – such as heralding stations – as a resource. When scaling quantum networks to many nodes, requiring a dedicated intermediary device for every pair of nodes introduces […]
