Spin Qubits produced with a 300mm fabrication line: An update on Intel Si/SiGe devices

The qubit is the fundamental device of a quantum computer. It is the equivalent to the transistor in CMOS logic devices. And while it took the semiconductor industry 42 years from the first transistor to the first 1M transistor microprocessor, the quantum community hopes to reach this milestone much faster. But there are no less than 10 qubit types and most require new materials and new inventions to realize even a few qubits. Of these qubit types, only spin qubits in silicon are similar to transistors and are compatible with the infrastructure of advanced CMOS fabrication. By leveraging all of the work in transistor fabrication, we can perhaps shorten accelerate the time. - The future of quantum computing starts with a grain of sand.



Si/SiGe quantum-dot based qubits are an excellent platform with demonstrated high fidelity control and leverage the proven reliability of semiconductor manufacturing to successfully demonstrate clean, high-yielding quantum-dot arrays. – In this talk, we will present recent results on our Tunnel Falls chip, introduce our next array of two dimensional devices, and highlight technical challenges that the spin qubit community should address.
