KEYNOTE: Leveraging Scalable Semiconductor Manufacturing for a Multi-Core Full-Stack QSoC on the Road Toward Quantum Utility

Quantum System on Chip is a dedicated qubit control processor for high density industrial scale silicon spin qubits. The requirements for controlling very large numbers of silicon qubits provide significant challenges, particularly in terms of precision control and low noise to create and manoeuvre qubits, (Signal to Noise) SNR to reliably measure the state of qubits using transport current, precision (Orthogonal Frequency Division Multiplexing) OFDM to create useful 1, and 2 qubit gates, and quantum error correction to turn physical qubits into logical qubits. All operating on a miniscule power budget. In this talk, we present the architecture, technology, circuits and techniques used in our QSoC processor and share our performances results we achieved.
