About Silicon Quantum Computing
Silicon Quantum Computing (SQC) is an Australian company that has developed the world's first integrated circuit manufactured at the atomic scale. The company's approach is centered on its ability to precisely manufacture quantum processors by placing individual phosphorus atoms, which act as qubits, into a silicon crystal. This technique allows for the creation of high-quality and stable quantum computing hardware.
