Double occupancy errors in quantum computing operations: Corrections to adiabaticity

Double occupancy errors in quantum computing operations: Corrections to adiabaticity

We study the corrections to adiabatic dynamics of two coupled quantum dot spin-qubits, each dot singly occupied with an electron, in the context of a quantum computing operation. Tunneling causes double occupancy at the conclusion of an operation and constitutes a processing error. We model the gate operation with an …
