So here's a fun quantum computing update for you. Shares of IonQ Inc. (IONQ) were moving higher in Wednesday's premarket session. Why? The company just got some serious government backing and showed off a neat technical trick.
First, the backing. IonQ was selected for DARPA's Heterogeneous Architectures for Quantum program, or HARQ. Announced on Tuesday, this initiative isn't about building a single, better quantum computer. It's about figuring out how to make different kinds of quantum computers talk to each other at high speed. Think of it like developing a universal USB-C cable, but for quantum bits—or qubits—that come in different flavors, like trapped ions and superconducting circuits. The goal is to stitch them together into a more powerful, networked system. Getting picked for this program is a vote of confidence in IonQ's tech and its role in making quantum systems scalable.
Now, the neat trick. In what seems like perfectly timed news, IonQ also said on Tuesday that it hit a key technical milestone. The company managed to connect two of its own trapped-ion quantum systems that were sitting apart from each other. They did it using photonic interconnects—basically, using particles of light (photons) to create a quantum link.
This is a big deal because it validates the process of generating, transmitting, and detecting the photons needed to create quantum entanglement over a distance. Entanglement is that spooky quantum connection where particles become linked, and what happens to one instantly affects the other, no matter how far apart they are. IonQ is calling this the first demonstration of linked commercial quantum computers. It moves the concept out of a pure research lab and into a more practical, commercial setting.
The result supports theoretical approaches that have suggested photonic links could connect separate trapped-ion systems without losing their delicate quantum state, or coherence. It's a tangible step toward the vision of distributed quantum computing, where you might network several processors together to tackle problems too big for any one machine.
IonQ is a quantum platform and merchant supplier, which means it delivers integrated solutions across computing, networking, sensing, and security. These two announcements—the DARPA selection and the photonic link demo—play directly into the networking part of that mission.
Investors seemed to like the news. According to market data, IonQ shares were up 7.02% at $38.27 during premarket trading on Wednesday.
