Socionext to develop quantum controller chips for Google
Socionext in Japan has signed a strategic partnership with Google Quantum AI for the first time. The two companies will develop controller SoCs for Google Quantum AI’s next-generation quantum computing system.
Google has developed a 105 qubit quantum processor with real time error correction. The next generation systems will need dedicated control system chips.
The Willow processor uses superconducting metals to form resonant circuits with capacitance and inductance coupled with Josephson junctions as nonlinear elements. By carefully choosing materials with a specialist fabrication process, the qubits can be integrated into large, complex devices. These are built in a specialist fab in Santa Barbara, California.
The qubits are controlled with microwave signals, which are delivered through specialist interconnect from room temperature all the way to extremely low temperatures. The wires incorporate filtering to protects the qubits from being affected by external noise.

- Socionext teams with TSMC, ARM on 2nm chiplet development
- World’s coldest ARM processor
- Inside Microsoft’s transistor for the quantum age
Socionext has a long history in semiconductor technology and development. This new partnership focused on quantum computing system controllers uses its established expertise in high-precision, high-quality semiconductor devices. It already works with TSMC and ARM, which has shown its processors working in cryogenic systems.
Socionext is restructuring its management board, adding newly appointed president Hisato Yoshida as chief operating officer (COO) and Global Leading Group (GLG) Co-Lead and Development Group Lead under CEO Masahiro Koezuka. Rajinder Cheema has been appointed executive VP and chief technology officer as well as Global Leading Group (GLG) Co-Lead.
