Using a quantum dot spin bus to implement CNOT gates between remote qubits - Possible suggestions...
A spin bus is a chain of individual spins with strong, always-on, static interactions (e.g., a linear array of single-electron quantum dots).~ Here, we consider

cnotGate - CNOT gate (controlled X gate) - MATLAB
This MATLAB function applies a controlled NOT gate to a target qubit based on the state of a control qubit and returns a quantum.gate.SimpleGate object.
