Michelle Simmons on Silicon Quantum Computing's Atomic Qubits & Products

Unique Quantum Computing Approach

• 💡 Silicon Quantum Computing (SQC) utilizes phosphorus atoms in isotopically pure silicon-28 to create high-fidelity, low-noise qubits with exceptional coherence.
• 🔬 Their quantum processing unit (QPU) uses only two atoms (phosphorus and silicon), ensuring high stability, low noise, and natural qubit formation.
• ⚡ SQC designs phosphorus-doped wires for control circuitry, enabling atomic-scale precision and low-noise operation.

Industry-Leading Performance

• ✅ SQC has demonstrated all-to-all connectivity within multi-nuclear spin registers, facilitating multi-qubit operations.
• 📈 They achieve high fidelities: 99.99% for single-qubit gates and 99.95% for two-qubit gates and readout, even when including all losses and errors.
• 🎯 A 4-qubit system achieved 98.87% fidelity on Grover's algorithm without error correction, showcasing native raw fidelity.
• 🛠️ Precision manufacturing with sub-nanometer accuracy is crucial for their speed and qubit quality.

Product Offerings & Scaling

• 🚀 SQC offers three products: Quantum Machine Learning (available now), Analog Simulation for mimicking molecules, and Fault-Tolerant Quantum Computing as a long-term goal.
• 💡 Their QML product enhances classical machine learning for sparse or time-series data, with customer validation and a launch expected mid-year.
• 🧩 The system supports up to six qubits per register controlled by a single gate, and registers can be connected for larger, scalable architectures.
• 🧊 A 10,000-qubit system is designed to fit on a single wafer within one dilution fridge, leveraging existing silicon technology.

Company Vision & Future

• 🗓️ SQC predicts an error-corrected system by 2033, basing this timeline on the historical development of classical computing.
• 💰 Accelerating their roadmap primarily requires increased funding to expand their manufacturing operations.
• 🇦🇺 Michelle Simmons highlights Australia's collaborative and competitive culture as a unique advantage for the company.
