If I had to pick one quantum computing stock that looks set up for disappointment after its upcoming earnings, Quantum Computing Inc. (NASDAQ: QUBT) would be near the top of the list.
The company has a genuinely interesting photonics story, but the way the numbers line up heading into Q2 earnings (coming on Monday, Aug. 10) makes it easy for reality to fall short of the hopes built up around it.
Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a “Double Down” signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same “Total Conviction” signal is flashing for a company 1/100th the size of Nvidia. Continue »

QCI’s first-quarter 2026 results read like a classic early‑stage deep-tech profile. Revenue jumped from $39,000 a year ago to $3.7 million, driven mostly by acquiring Luminar Semiconductor and NuCrypt, not by organic growth in its existing quantum products. Operating expenses soared to $19.8 million, up 139%, as the company added people and absorbed transaction costs. It still posted a net loss of $4.1 million despite ending the quarter with about $1.4 billion in cash, cash equivalents, and investments on the balance sheet.
That mix of tiny revenue, big losses, and huge cash is unusual. It creates an expectation that QCI will turn that war chest into visible traction fast.
Quantum Computing Inc. is in the early stages
Underneath those numbers is a broad but early business. QCI is positioning itself as a vertically integrated photonics and quantum optics company, with room‑temperature quantum optimization systems in its Dirac line, reservoir‑computing hardware for machine learning, thin‑film lithium niobate photonic chips, and sensing and cybersecurity devices. It runs Fab 1 in Arizona to manufacture TFLN photonic integrated circuits and has won contracts, including one from NIST, to design and fabricate those chips. As of March 31, the contract backlog was about $16 million, which does give…
