Zeeman-like coupling to valley degree of freedom in Si-based spin qubits (opens in new tab)

Author(s): S. A. Jafari, Hendrik Bluhm, and David P. DiVincenzoIncreasing the valley splitting in Si-based heterostructures is critical for improving the performance of semiconductor qubits. This paper establishes that the two low-energy conduction band valleys are not independent parabolic bands. Instead, they originate from the X point of the Brillouin zone, …[Phys. Rev.
