Hitting the Quantum 'Sweet Spot': Researchers Find Best Position for Atom Qubits in Silicon

Researchers from Australia's Center of Excellence for Quantum Computation and Communication Technology (CQC2T) at the University of New South Wales Sydney (UNSW), working with colleagues at Australia’s Silicon Quantum Computing firm, identified the ideal positioning for qubits in silicon in order to scale up atom-based quantum processors. Precise placement of phosphorus atoms in silicon is necessary to produce robust interactions between qubits, which CQC2T's Sven Rogge said are needed "to engineer a multi-qubit processor and, ultimately, a useful quantum computer." CQC2T's Benoit Voisin said scanning tunneling microscope (STM) lithography techniques developed at UNSW can find the "special angle, or sweet spot, within a particular plane of the silicon crystal where the interaction between the qubits is most resilient." ....
