Molecular spins are rising platforms for quantum info processing. By chemically tuning their molecular construction, it’s potential to arrange a strong setting for electron spins and drive the meeting of numerous qubits in atomically exact spin-architectures. Principal challenges in the direction of the combination of molecular qubits into solid-state gadgets are i) minimizing the interplay with the supporting substrate to suppress quantum decoherence and ii) controlling the spatial distribution of the spins on the nanometer scale to tailor the coupling amongst qubits. Herein, we offer a nanofabrication technique for the belief of a 2D patterned array of individually addressable Vanadyl Phthalocyanine (VOPc) spin qubits. The molecular nanoarchitecture is crafted on high of a diamagnetic monolayer of Titanyl Phthalocyanine (TiOPc) that electronically decouples the digital spin of VOPc from the underlying Ag(100) substrate. The isostructural TiOPc interlayer additionally serves as a template to control the spacing between VOPc spin qubits on a scale of some nanometers, as demonstrated utilizing scanning tunneling microscopy, X-ray round dichroism, and density useful principle. The long-range molecular ordering owes to a mixture of cost switch from the metalic substrate and pressure within the TiOPc interlayer, which is attained with out altering the pristine VOPc spin traits. Our outcomes pave a viable route in the direction of the longer term integration of molecular spin qubits into solid-state gadgets.
