Abstract
A quantum computer comprises a pair of qubits disposed between first and second single-electron electrometers and a control gate. The qubits each comprise a molecule of ammonia caged inside a C60 molecule disposed on a substrate. The ammonia-bearing C60 molecule is positioned using a scanning probe microscope.
