Figure 2. Molecular structure of the asymmetric two-qubit assembly for proposed implementation of a CNOT gate.

Figure 2

(a) Molecular structure of [{Cr7Ni-O2C-py}→Co(SCN)2←{Cr7Ni-O2C-terpy}] 5. nPr2NH2+ cations are not shown (H atoms and tert-butyl groups are omitted for clarity). Colour code: Co, dark red; Cr, green; Ni, purple; Ru, brown; N, cyan; O, red; S, yellow; C, grey; F, pale green. (b) Schematic representation of the effect of the CNOT gate on a pair of qubits, initialized in the computational basis states Inline graphic and Inline graphic, respectively. The CNOT flips the target qubit if the control is set to Inline graphic.
