Infleqtion, Silicon Light Machines Strike Component Integration Partnership
BOULDER, Colo., Oct. 10, 2025 — Neutral atom quantum technology company Infleqtion has entered into a partnership with Silicon Light Machines. The collaboration integrates Silicon Light Machines’ novel microelectromechanical systems (MEMS) displacement phase modulator (DPM) into Infleqtion’s neutral atom quantum computing systems. According to the companies, the integration will enable system performance gains and improve quantum computer scaling.
Silicon Light Machine's silicon-germanium MEMS technology integrates high-speed, noncontact piston phase modulators onto CMOS drivers. The technology aims to enable faster phase modulation, which is critical for advanced quantum applications such as individual qubit addressing, as well as optical multiplexing and scalable laser processing applications.
“Integrated photonics are central to Infleqtion’s strategy for advancing neutral atom systems and commercializing quantum technologies,” said Paul Morton, CTO Photonics at Infleqtion. “Our future quantum products will leverage advanced [PICs] for miniaturization, cost reduction, and enhanced ruggedness across three critical domains: laser systems, frequency control, and atom addressing.
"The Silicon Light Machines' DPM device represents a breakthrough in fast and scalable atom addressing, our neutral atom quantum computing platform,” Morton said.
Infleqtion’s neutral atom quantum computers use laser-based optical tweezers to manipulate thousands of individually trapped atoms, allowing high-speed, high-fidelity operations across large-scale qubit systems. This architecture supports advanced features including dual-species arrays for low-overhead mid-circuit measurement and efficient error correction, which are key enablers for scalable, fault-tolerant computing.
Infleqtion already partners with Thorlabs for the commercialization of its integrated optical fiber collimation package. The package delivers a linearly polarized collimated beam with high extinction ratio and integrated power monitoring for quantum technology applications. The company additionally completed a $100 million funding round targeting the scaling of its solutions earlier this year.
This current news follows Infleqtion's announcement last month that it plans to become a publicly traded company via a merger with Churchill Capital Corp X. The company's valuation as of the September announcement is $1.8 billion
