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…
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…
Ideal refocusing of an optically active spin qubit under strong hyperfine interactions
Leon Zaporski, Noah Shofer, Jonathan H. Bodey +15
Combining highly coherent spin control with efficient light-matter coupling offers great opportunities for quantum communication and networks, as well as quantum computing. Optical…
Direct measurement of hyperfine shifts and radiofrequency manipulation of the nuclear spins in individual CdTe/ZnTe quantum dots
G. Ragunathan, J. Kobak, G. Gillard +5
We achieve direct detection of electron hyperfine shifts in individual CdTe/ZnTe quantum dots. For the previously inaccessible regime of strong magnetic fields T, w…
Dynamical suppression of fluctuations in an interacting nuclear spin bath of a self-assembled quantum dot using multiple pulse nuclear magnetic resonance
A. M. Waeber, M. Hopkinson, M. S. Skolnick +1
Electron spin qubit coherence in quantum dots is ultimately limited by random nuclear spin bath fluctuations. Here we aim to eliminate this randomness by making spin bath evolution…
