Coherent Control of Quantum-Dot Spins with Cyclic Optical Transitions
Zhe Xian Koong, Urs Haeusler, Jan M. Kaspari +14
Solid-state spins are promising as interfaces from stationary qubits to single photons for quantum communication technologies. Semiconductor quantum dots have excellent optical coh…
Low-density InGaAs/AlGaAs Quantum Dots in Droplet-Etched Nanoholes
Saimon F. Covre Da Silva, Ailton J. Garcia, Maximilian Aigner +10
Over the past two decades, epitaxial semiconductor quantum dots (QDs) have demonstrated very promising properties as sources of single photons and entangled photons on-demand. Amon…
Few-electron spin qubits in optically active GaAs quantum dots
Peter Millington-Hotze, Petr Klenovsky, Harry E. Dyte +5
The knowledge of the energy spectrum completely defines the dynamics of a quantum system for a given initial state. This makes spectroscopy a key characterization technique when st…
Optical and magnetic response by design in GaAs quantum dots
Christian Schimpf, Ailton J. Garcia, Zhe X. Koong +24
Quantum networking technologies use spin qubits and their interface to single photons as core components of a network node. This necessitates the ability to co-design the magnetic-…
Storing quantum coherence in a quantum dot nuclear spin ensemble for over 100 milliseconds
Harry E. Dyte, Santanu Manna, Saimon F. Covre da Silva +2
States with long coherence are a crucial requirement for qubits and quantum memories. Nuclear spins in epitaxial quantum dots are a great candidate, offering excellent isolation fr…
