Quantum Computing Inc. (QUBT -0.71%) has gone from a little-known quantum computing stock to a company trying to build a real hardware business around photonics, semiconductor manufacturing, and quantum security. Its revenue growth suggests that customers are beginning to show up, but it's still losing money and asking investors to bet on an ambitious strategy that will be costly and difficult to execute.
Here's where the company, also known as QCi, stands today, what it is trying to build, and why the opportunity comes with considerable risk.

Key Data Points
Where Quantum Computing Inc. is today
Quantum Computing Inc. describes itself as a "vertically integrated quantum company" built around photonics and semiconductor manufacturing, not just software or cloud access to quantum computers. It's listed on the Nasdaq and has moved from almost no revenue in 2025 to revenues of a few million dollars per quarter in 2026, but it still reports meaningful losses.
In its second‑quarter release, the company highlighted revenue of $5.6 million, up from $61,000 in the same quarter last year, but a net loss of $11.8 million. The top-line growth shows that QCi is no longer just a pre‑commercial story, but the bottom-line losses remind you that this business is still spending heavily to develop its technology and get its manufacturing platform off the ground.

What QCi is trying to build
The more interesting part of QCi's story lives outside the income statement. The company has been assembling a stack that runs from photonic chips in a fab to full quantum computers and security platforms, as the TechJournal.uk Substack details. It has been doing this largely through a series of acquisitions such as NHanced Semiconductors and other photonics and packaging businesses. Management's "vertically integrated" language reflects the fact that QCi wants to control the critical pieces of quantum computing hardware (think chips, components, and packaging), rather than simply renting time on someone else's machines.
What I have my eyes on is the product side. QCi has announced NeuraWave, a photonic computing platform meant to handle real‑time AI inference at the edge. In other words, it's building hardware that can run complex models close to where data is generated rather than in distant data centers. It also showed off a quantum security system at the ECOC 2026 trade show that could help telecom companies keep their fiber networks safe. The bigger point is that quantum technology is starting to look less like a science project and more like something companies can actually deploy for commercially meaningful uses.
The risks under the promise
The problem, in my view, is that QCi is trying to do a lot of hard things at once: scale up its manufacturing, integrate multiple acquisitions, sell new classes of hardware, and educate customers on how to use quantum security and photonic computing. And it's doing all of these things while it's still losing money. That's a lot of execution risk, particularly for a stock that has a history of volatile and sentiment‑driven price moves. It's easy to be bearish about QCi; there isn't much revenue, and its heavy spending and reliance on secondary stock sales to raise operating capital make its current valuation hard to justify.
There's also competitive risk. Quantum computing hardware, quantum security, and edge AI are all crowded spaces, and QCi hasn't yet shown large, recurring deployments at the scale you'd want to see before calling it a durable growth story. Its recent revenue ramp-up is encouraging, but that growth came off an extremely small base, and investors have to assume that more capital spending, more technical risk, and more time will be needed before the company's platform will be mature.
If you're fascinated by quantum hardware and photonics and you accept that this is still a high‑risk, high‑uncertainty space, QCi might be worth a spot on your watch list or in the "small, experimental slice" of a diversified portfolio.
