Spin qubit in a gated quantum dot
= Spin qubit in a gated quantum dot
A single confined <electron>'s two <spin> states form a <qubit> when initialization, coherent rotations and measurement are controlled. Local driving rotates one <spin>; gate-controlled exchange can entangle neighboring dot <spins>. <Spin-to-charge conversion> permits electrical readout. Observing charge blockade alone does not demonstrate coherent <qubit> operation.
