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…
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…
Quantum non-demolition measurement of an electron spin qubit through its low-energy many-body spin environment
Harry E. Dyte, George Gillard, Santanu Manna +3
The measurement problem dates back to the dawn of quantum mechanics. Here, we measure a quantum dot electron spin qubit through off-resonant coupling with thousands of redundant nu…
Approaching a fully-polarized state of nuclear spins in a semiconductor quantum dot
Peter Millington-Hotze, Harry E. Dyte, Santanu Manna +3
Magnetic noise of atomic nuclear spins is a major problem for solid state spin qubits. Highly-polarized nuclei would not only overcome this obstacle, but also make nuclear spins a…
Hyperfine-interaction limits polarization entanglement of photons from semiconductor quantum dots
Christian Schimpf, Francesco Basso Basset, Maximilian Aigner +12
Excitons in quantum dots are excellent sources of polarization-entangled photon pairs, but a quantitative understanding of their interaction with the nuclear spin bath is still mis…
Nuclear spin diffusion in the central spin system of a GaAs/AlGaAs quantum dot
Peter Millington-Hotze, Santanu Manna, Saimon F. Covre da Silva +2
The spin diffusion concept provides a classical description of a purely quantum-mechanical evolution in inhomogeneously polarized many-body systems such as nuclear spin lattices. T…
