It's shaping up to be a watershed year for Infleqtion.

The quantum hardware, software, and sensing company is positioned to capitalize on two of today's biggest trends: quantum technology and the commercial space industry.

"I like to say the only thing better than quantum is quantum in space," CEO Matt Kinsella told Barron's in a recent interview. "It's incredible how big the market opportunity will be."

Less than a month after going public through a blank-check merger, the company made headlines when it said it was providing upgraded quantum hardware to the International Space Station through a NASA cargo mission.

Just days later, Infleqtion said it had secured a $2 million contract from the U.S. Defense Advanced Research Projects Agency, an offshoot of the Defense Department. The company has been tasked with developing advanced software for hybrid quantum computing networks.

Kinsella champions quantum applications in national security and has shaped the company around this niche. Aside from quantum computers themselves, Infleqtion is developing technologies like quantum sensors and atomic clocks that lend themselves to precision timing and navigation.

Much of that technology has roots in the 2024 acquisition of two companies, Morton Photonics and SiNoptiq, which added over 40 foundational patents to the company's portfolio. It's an approach similar to IonQ's strategy of using targeted acquisitions to build specialized capabilities and stand out in the market.

Even the buzzy space stuff is tied to national priorities. Kinsella noted that the company is working on a larger program with NASA's Jet Propulsion Laboratory that aims to fly the first-ever quantum sensor for measuring Earth's gravitational field in orbit.

Gravity shifts reveal changing mass on the planet's surface, allowing the government to track everything from depleting global water tables to covert underground infrastructure.

Kinsella expects these initiatives to draw attention to Infleqtion's inertial sensing business, particularly its new Quantum Spectrum product line, which is designed to replace traditional antennas and analog receivers with atom-based radio frequency hardware.

"We're focusing on that significantly more because of the demand signals we're seeing for it," Kinsella said. "The same way we can turn our atoms into qubits or sensors, we can turn them into antennas."

A lifelong venture capitalist, Kinsella is the rare breed of quantum CEO who doesn't hail from the world of scientific research. Before joining Infleqtion, he served as a senior managing director at Maverick Ventures, where he led investments in technology.

Kinsella first became involved with the company as a director and investor in 2018, roughly a decade after Infleqtion's founding. He was elevated to the company's top role in April 2024, replacing Scott Faris, who stepped down to focus on quantum policy.

Infleqtion is on its third CEO since its inception, but Dana Anderson -- the professor who co-founded the company as ColdQuanta in 2007 -- remains on board as chief science officer. Anderson's enduring presence serves as a stamp of validation on Infleqtion's differentiated approach to quantum technology.

And what is the differentiator? Infleqtion's edge lies in neutral atoms, an up-and-coming architecture increasingly viewed as a commercially viable path forward.

This architecture uses individual atoms held in place by laser beams, which serve as qubits, or the fundamental units of information in a quantum computer. By cooling and manipulating these atoms, scientists can entangle them and perform highly precise computations.

Joe Fitzsimons, CEO of recently public Horizon Quantum, views neutral atoms as a promising path forward.

"Neutral atoms are scaling to higher qubit numbers than anything else," Fitzsimons told Barron's. "They've really kind of leapt onto the radar in the last two or three years."

Before then, "I don't think they were viewed as a leading contender, but they have really shot forward," Fitzsimons continued. The executive, a veteran researcher himself, attributes the excitement to a landmark Harvard University paper from December 2023 that successfully demonstrated error correction using neutral atoms.

"Up to that point, the highest number of encoded qubits anyone has done any experiments with was two or three, and they jumped straight to 48," Fitzsimons explained.

That result is significant for an industry racing to build larger, commercially viable quantum systems -- a feat that requires balancing raw size with the compounding errors that naturally occur as systems scale.

Neutral atoms may be slower than other approaches, but the scalability and ability of the surrounding systems to operate at room temperature provide a compelling commercial edge. Infleqtion has delivered 100-qubit and 500-qubit systems to research institutions in the UK and Japan, respectively.

Quarterly earnings last week offered the first real proof of concept for the newly public company. Infleqtion's per-share loss narrowed to 26 cents from 41 cents in the prior year, while revenue increased 14% to $9.5 million.

"For me, dealing with Wall Street is kind of like a comfort zone," Kinsella told Barron's shortly after the release. "I know the lingo and how to communicate with them. And I think the reception to the story has been quite strong, in that it's very differentiated to other quantum stories."

That narrative will be vital as the company tries to wrestle investor attention from its larger peers. Infleqtion's market capitalization hovered around $2.3 billion on Wednesday, making it roughly one ninth the size of IonQ and one-third the size of D-Wave Quantum.

Still, Infleqtion's modest scale doesn't mean it should be overlooked. The company is one of just a handful of players pioneering neutral-atom architecture, and serves as the public market's solitary vehicle for investing in the technology.

French start-up Pasqal, another developer of neutral-atom quantum systems, is slated to go public later this year. CEO Wasiq Bokhari hopes the listing will boost the company's visibility among both retail and institutional investors in the U.S.

"They will get a chance to know us better," Bokhari told Barron's.

The market continues expanding, even as quantum remains a speculative bet. But the risk/reward profile offers massive potential upside for those willing to wait until the technology fulfills its long-held promises. Just take it from Kinsella himself.

"The biggest surprise to the upside since I first invested in the company has been the progress that neutral atoms have made on quantum computing -- it was always pretty clear they could build a decent business in sensing," Kinsella said. "What at the time was a very out-of-the-money call option in 2018 is becoming more and more real. I think we're going to see a world where neutral atoms wins, and I think we can win neutral atoms, which means we can win it all."
