Infleqtion and Silicon Light Machines Partner to Boost Quantum Computer Performance

Insider Brief

Infleqtion partnered with Silicon Light Machines to integrate SLM’s MEMS Displacement Phase Modulator into its neutral-atom quantum computers, aiming to boost speed, fidelity, and scalability.
SLM’s SiGe MEMS DPM mounts high-speed non-contact piston phase modulators on CMOS drivers to enable faster phase modulation for individual qubit addressing, optical multiplexing, and scalable laser processing.
The collaboration strengthens Infleqtion’s integrated photonics roadmap and scaling of dual-species arrays while it prepares to go public via a merger with Churchill Capital Corp X (NASDAQ: CCCX).

Infleqtion, a global leader in neutral atom-based quantum technology, announced a strategic partnership with Silicon Light Machines, a micro-electro-mechanical systems (MEMS) innovator based in Silicon Valley. The collaboration explores integration of Silicon Light Machines’ novel MEMS Displacement Phase Modulator (DPM^TM) technology into Infleqtion’s neutral atom quantum computing systems, to unlock unprecedented performance gains and enable quantum computer scaling. This news follows the announcement Infleqtion plans to go public via a merger with Churchill Capital Corp X (NASDAQ: CCCX).

SLM’s silicon-germanium (SiGe) MEMS technology integrates high-speed, non-contact piston phase modulators onto CMOS drivers to enhance both performance and reliability. These innovations enable faster phase modulation that 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 photonic integrated circuits (PICs) for miniaturization, cost reduction, and enhanced ruggedness across three critical domains: laser systems, frequency control, and atom addressing. The SLM DPM device represents a breakthrough in fast and scalable atom addressing, our neutral atom quantum computing platform.”

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 like dual-species arrays for low-overhead mid-circuit measurement and efficient error correction, which are key enablers for scalable, fault-tolerant computing.

“Infleqtion leads the field in scaling neutral atom quantum systems,” said Thomas Noel, Vice President of Quantum Computing, Infleqtion. “We are exploring how the speed and flexibility enabled by Silicon Light Machines’ DPM^TMwill help us accelerate that leadership by increasing the operating speed of our hardware and ultimately reducing the application runtime for our customers.”

The partnership and DPM^TM integration are a strategic step towards enhancing the critical photonics technologies and components needed to effectively scale Infleqtion’s neutral atom quantum computer.

“Quantum computing is transitioning from theoretical to transformational,” said Lars Eng, CEO of Silicon Light Machines. “Our DPM™ technology offers the precision and speed needed to meet the scalability demands of neutral atom systems. We’re proud to partner with Infleqtion to help bring quantum into real-world applications.”
