What is the significance of controlling orbital qubits in quantum information technologies?

Controlling orbital qubits is crucial for photonic quantum information technologies. The orbital degree of freedom in optically active quantum dots has emerged as a promising candidate, but the ability to perform arbitrary rotations on orbital qubits remains elusive. Recently, researchers have demonstrated the importance of controlling orbital states in solid-state quantum emitters for applications in high-speed quantum information processing.

The control of orbital qubits is essential because it enables direct manipulation of polar and azimuthal angles of the Bloch vector without requiring timed precession.
