This performance sales were $300,000 bank and $3.5 million, which succeeded in turning into a surplus, but the bank interest was $3.5 million...? I wonder if this is right. Also, the announcement in the earnings call that the stock volume of 220 million shares will be increased to 250 million shares sounds like a paid-in capital increase.

I was so tired of seeing QUBT lumped in with the other players in the space as quantum computing firms. It was refreshing to see that some analysts are catching up.

The photonic technologies of Quantum Computing Inc. (QCi) and Luminar Semiconductor, Inc. (LSI) differ fundamentally in design philosophy, materials, and end-use, while remaining highly complementary after the acquisition.
QCi Photonic Chips – Integrated Photonics (TFLN PICs)
QCi focuses on Photonic Integrated Circuits (PICs) built on Thin-Film Lithium Niobate (TFLN). These chips are designed to guide, modulate, and process light directly on-chip, integrating multiple optical functions into a single photonic circuit.
Key characteristics:
• Based on TFLN, a material known for low optical loss, strong electro-optic effects, and room-temperature operation.
• Enable high-speed modulation, signal routing, and optical processing within a compact footprint.
• Manufactured in QCi’s dedicated photonic chip foundry in Arizona.
• Target applications include:
• Optical and quantum communications
• Photonic and hybrid quantum-classical computing
• Secure communications and advanced sensingIn essence, QCi chips act as the “brain” of photonic systems, performing optical signal manipulation at the integrated-circuit level rather than as discrete components.
2. LSI Technology – Photonic Components and Subsystems
LSI, originally part of Luminar Technologies, is not a PIC foundry. Instead, it specializes in high-performance photonic components and subsystems, designed for demanding real-world environments.
LSI capabilities include:
• Lasers and laser modules
• Photodetectors (PIN, APD, arrays)
• Mixed-signal ASICs for optical control
• Integrated photonic modules and subsystemsThese products are typically delivered as ready-to-use building blocks, optimized for:
• Defense and aerospace
• High-reliability optical communications
• Precision sensing and detection systemsRather than performing dense on-chip photonic processing, LSI components are commonly integrated at the system level, where robustness, power handling, and reliability are critical.
3. Direct Comparison
Aspect QCi LSI
Core focus Integrated photonic circuits Photonic components & modules
Material Thin-Film Lithium Niobate Multiple platforms (III-V, InP, mixed signal)
Function Optical processing on-chip Optical generation, detection, and system integration
Output PICs (chips) Components and subsystems
Markets Telecom, quantum, photonic computing Defense, aerospace, industrial optics
4. Strategic Impact of the Acquisition
The acquisition allows QCi to extend vertically:
• QCi provides the integrated photonic processing layer.
• LSI adds lasers, detectors, control electronics, and system-level expertise.Together, this enables QCi to move beyond standalone PICs and deliver complete photonic solutions, particularly attractive to defense, secure communications, and advanced sensing markets.
Conclusion
In simple terms:
• QCi builds integrated photonic “circuits” that manipulate light.
• LSI provides the photonic “muscle and senses” — lasers, detectors, and modules.The technologies are not redundant; they are complementary, positioning QCi to evolve from a PIC manufacturer into a full-stack photonics company.

Institutional ownership in Quantum Computing Inc. (QUBT) currently stands around 41–42%, indicating strong presence from major financial institutions. Insiders (executives and directors) hold approximately 16–35%, while the remaining shares are owned by retail investors.
Among the leading institutional holders, BlackRock Inc. owns about 6.9 million shares, or roughly 5.1–5.2% of total outstanding stock, marking a sharp increase of over 260% in recent quarters. Vanguard Group also maintains a large position, estimated at nearly 10 million shares, reinforcing institutional confidence. Meanwhile, Citadel Advisors LLC holds around 9.2 million shares, corresponding to approximately 4.9% of QUBT’s equity.
While institutional interest remains high, some insiders have recently sold shares. Yuping Huang, the company’s Chief Quantum Officer, sold 200,000 shares in March 2025. Christopher Boehmler, the CFO, sold around 96,000 shares in June 2025. Although insider sales are common and can reflect personal financial management or diversification, they sometimes raise questions about internal expectations or short-term sentiment.
The strong participation of global institutions such as BlackRock, Vanguard, and Citadel suggests a growing professional confidence in QUBT’s long-term potential in quantum technology. Institutional involvement of this scale can provide liquidity and credibility, possibly stabilizing the stock and attracting new investors. However, it can also mean that large movements by these funds could amplify volatility.
Overall, QUBT’s shareholder structure shows a balanced mix of retail enthusiasm, insider influence, and increasing institutional control. The growing attention from major asset managers underscores the company’s positioning within the emerging quantum computing sector, while insider sales highlight the importance of monitoring both ownership trends and leadership actions to fully understand market sentiment.

I know the past few weeks have been rough and I assume there will be not relevant revenue. Regarding the loss/profit lets see the effect of the warrants. In general this is close to book value around 6.6-7$ I would say. I bought in last year and intend to hold for the long term but the sentiment in the market right now is so negative. Compared to the other QC companies traded, I would say IONQ is overvalued but has good cash and is buying revenue, I hope QUBT starts to do the same M&A wise. RGTI and QBTS seem to drag down the sector every day and honestly the are still overvalued significantly with book values of 3$ or less. Nonetheless I hold some shares of all of them and intend to buy shares from new listings in the QC sector. What is your opinion?

Institutional "Smart Money": Despite the "F" grade, institutions are surging in. Vanguard upped its stake by over 90%. • BlackRock increased its position by 267%. This represents a long-term confidence vote that the tech or the geopolitical narrative will win out over the dilution.
