Interview
Compact Spin Qubit Quantum Computer
Summary
At the APS meeting, Quantum Machines’ Jonathan Reiner and Equal1’s Mike showcased Equal1’s Bell quantum computer, a fully integrated, rack-mounted quantum system that combines cryogenics, qubits, and Quantum Machines’ control hardware into a compact, plug-and-play platform for scalable silicon spin qubit research.
Highlights
- Compact integration: The entire 6-qubit silicon–germanium system, including cryostat and cooling to 300 mK, fits in a single standard server rack powered by one outlet.
- Scalable roadmap: Equal1 plans to expand from 6 to 17 qubits by year-end and to 50 qubits next, leveraging silicon’s scalability.
- Precision control: Quantum Machines’ QDAC, OPX, and Octave enable ultra-stable DC biasing, GHz-range qubit control, and real-time reflectometry feedback.
- Accessible design: The system supports both remote and offline operation with pulse-level programmability, making advanced quantum experimentation accessible beyond specialized cryo labs.
