Hole spin qubits in semiconductor quantum dots

Hole spin qubits in semiconductor quantum dots allow ultrafast electrical control, and are considered an intriguing candidate as the building block for a scalable quantum computer. Here we develop a theory with the objective of understanding how an alternating electric field can couple the two heavy hole states in a two-dimensional quantum dot to allow electric dipole

spin resonance. We work within the effective mass approximation and the envelope function approach, and explore influences of system parameters such as the interface electric field and form of confinement potential.
