Maximizing the purity of a qubit evolving in an anisotropic environment
Xiaoya Judy Wang, Stefano Chesi, W. A. Coish
We provide a general method to calculate and maximize the purity of a qubit interacting with an anisotropic non-Markovian environment. Counter to intuition, we find that the purity…
Controlling hole spins in quantum dots and wells
Stefano Chesi, Xiaoya Judy Wang, W. A. Coish
We review recent theoretical results for hole spins influenced by spin-orbit coupling and Coulomb interaction in two-dimensional quantum wells as well as the decoherence of single…
Spin-echo dynamics of a heavy hole in a quantum dot
Xiaoya Judy Wang, Stefano Chesi, William A. Coish
We develop a theory for the spin-echo dynamics of a heavy hole in a quantum dot, accounting for both hyperfine- and electric-field-induced fluctuations. We show that a moderate app…
