Hyperfine-phonon spin relaxation in a single-electron GaAs quantum dot
Hyperfine-phonon spin relaxation in a single-electron GaAs quantum dot
Understanding and control of the spin relaxation time T1 is among the key challenges for spin-based qubits. A larger T1 is generally favored, setting the fundamental upper limit to the qubit coherence and spin readout fidelity. In GaAs quantum dots at low temperatures and high in-plane magnetic fields B, the …
