Spin qubits with electrically gated polyoxometalate molecules
Spin qubits offer one of the most promising routes to the implementation of
quantum computers. Very recent results in semiconductor quantum dots show that
electrically-controlled gating schemes are particularly well-suited for the
realization of a universal set of quantum logical gates. Scalability to a
larger number of qubits, however, remains an issue for such semiconductor
quantum dots. In contrast, a chemical bottom-up approach allows one to produce
identical units in which localized spins represent the qubits. Molecular
magnetism has produced a wide range of systems with tailored properties, but
molecules permitting electrical gating have been lacking. Here we propose to
use the polyoxometalate [PMo12O40(VO)2]q-, where two localized spins-1/2 can be
coupled through the electrons of the central core. Via electrical manipulation
of the molecular redox potential, the charge of the core can be changed. With
this setup, two-qubit gates and qubit readout can be implemented.Comment: 9 pages, 6 figures, to appear in Nature Nanotechnolog
