Air Force contract ignites rally in the quantum sector
The U.S. Air Force Research Laboratory (AFRL) announced a three‑year, $5.8 million contract that pairs Rigetti Computing with the Dutch quantum‑tech startup QphoX. The award centers on building a bridge between superconducting qubits—Rigetti’s core technology—and optical photons, which can travel through fiber without degrading. By converting the microwave signals that live inside a quantum chip into light, the collaboration hopes to create the first viable quantum‑optical network for defense‑grade applications.
When the news broke, Rigetti’s NASDAQ ticker RGTI surged past its previous peak, prompting a wave of buying across other publicly traded quantum firms. Traders cited the contract as validation that the federal government is moving from exploratory research to real‑world procurement in quantum information science. Within hours, a handful of peer stocks—ranging from IonQ to Pasqal—registered modest gains, signaling a broader confidence boost for the emerging industry.
AFRL’s principal research physicist, Matt LaHaye, emphasized that the ability to link distant superconducting processors could reshape Air Force operations. He referenced potential uses such as distributed sensing, secure communications, and rapid‑response computing for situational awareness. The contract, therefore, is not just a research grant; it is a strategic investment aimed at keeping U.S. defense capabilities ahead of peer competitors.
Technical roadmap and market implications
Both companies bring complementary expertise to the table. Rigetti supplies the superconducting microwave qubit platform that has already powered its Aspen quantum‑cloud service. QphoX, meanwhile, has demonstrated a single‑photon microwave‑optical transducer capable of converting qubit‑level signals into telecom‑band photons with minimal loss. The partnership’s roadmap includes three milestones:
- Year 1: Integrate QphoX’s transducer with a Rigetti 32‑qubit processor and achieve single‑shot optical readout.
- Year 2: Demonstrate entanglement swapping between two spatially separated qubits linked via a 10‑km fiber link.
- Year 3: Deliver a prototype quantum‑network node that can interface with existing Air Force telecom infrastructure for secure data transmission.
Successful completion would lay the groundwork for a “quantum local area network” that can distribute entanglement on demand—a capability that could underpin quantum‑enhanced radar, navigation, and cryptography. The commercial upside is equally compelling: a proven superconducting‑optical interface could unlock new markets in cloud‑based quantum services, where customers need to run algorithms on distributed hardware without exposing the delicate quantum states to environmental noise.
Market analysts remain cautiously optimistic. On one hand, the contract injects a credible revenue stream and validates Rigetti’s technical direction. On the other, the company’s multi‑billion‑dollar market cap still dwarfs its cash reserves, meaning sustained growth will depend on winning additional government or enterprise contracts. Still, the immediate market reaction suggests investors view the AFRL partnership as a catalyst that could accelerate both the firm’s financial footing and the broader commercial rollout of quantum networking technology.
