Quantum Computing Inc. (NASDAQ: QUBT) announced a $110 million all‑cash purchase of Luminar Semiconductor, Inc., a wholly owned subsidiary of Luminar Technologies, Inc. The deal follows Luminar Technologies’ voluntary Chapter 11 filing, which excluded Luminar Semiconductor from the bankruptcy docket and positioned the subsidiary for sale to a buyer that can preserve its technology and workforce.
The acquisition expands QUBT’s photonics platform by adding Luminar’s portfolio of chip‑scale photonic components, patents, and engineering talent. The added capabilities are expected to accelerate the development of compact, fully‑integrated quantum systems and open new revenue streams in non‑quantum photonics markets such as high‑bandwidth optical transceivers for data centers and defense‑grade sensing solutions.
QUBT’s recent financials underscore the strategic importance of the purchase. The company reported a $51.2 million net loss for Q4 2024, driven by higher operating expenses—including employee‑related costs and depreciation associated with bringing its Tempe Fab 1 foundry online. Despite the loss, QUBT raised substantial capital in 2025, giving it a cash runway to fund research, development, and the integration of Luminar Semiconductor’s assets.
Luminar Semiconductor specializes in chip‑scale photonic solutions for optical communications, industrial and gas sensing, and satellite and space photonics. Its technology portfolio includes high‑performance modulators, photonic integrated circuits, and laser sources that are already deployed in defense, aerospace, and commercial optical networks, providing QUBT with a diversified customer base beyond quantum‑specific applications.
The sale of Luminar Semiconductor triggered a sharp decline in Luminar Technologies’ stock, falling 65 % after the announcement, as investors reacted to the company’s Chapter 11 filing and the divestiture of a key asset. QUBT’s own market reaction was muted, reflecting the company’s focus on long‑term strategic positioning rather than immediate earnings impact.
Dr. Yuping Huang, CEO of QUBT, said the deal “represents a meaningful step forward in our strategy to develop and scale practical, integrated quantum solutions. By adding LSI’s technology and talent, we can serve and expand LSI’s existing non‑quantum customer base while accelerating the commercialization of quantum appliances.” Paul Ricci, CEO of Luminar, added that the partnership “provides LSI with a platform to grow its customer base and invest in markets with long‑term demand for high‑reliability optical systems.”
The transaction is subject to bankruptcy court approval, which could introduce timing risks or the possibility of higher offers. Nevertheless, the acquisition positions QUBT to strengthen its supply chain, broaden its product portfolio, and accelerate its roadmap for room‑temperature, low‑power quantum solutions, potentially giving it a competitive edge in the emerging quantum computing market.
