Quantum Computing Inc (QCi; QUBT) is a U.S. technology company focused on integrated photonics and quantum computing hardware and applications. Its portfolio centers on photonics-based “entropy quantum computing” devices, quantum-inspired computing for artificial intelligence workloads, quantum random number generation for cryptography, and quantum remote sensing and imaging systems. Quantum Computing Inc describes its machines as operating at or near room temperature and low power, with a focus on cost and accessibility for commercial and government users.

The company was formed in 2018 and, in June 2022, acquired QPhoton, a quantum photonics startup founded by physicist Yuping Huang, which became a wholly owned subsidiary of Quantum Computing Inc. As of April 2025, Huang serves as interim chief executive officer and president following the retirement of CEO William McGann; co-founder Robert Liscouski is chairman of the board.

History

Quantum Computing Inc traces its origins to 2018, when it was incorporated in Delaware and began operations in Leesburg, Virginia, with a strategy to develop “quantum-ready” software and tools for optimization problems. In June 2022, the company shifted toward integrated photonics hardware by acquiring QPhoton, Inc., a quantum photonics developer whose founder, Dr. Yuping Huang, joined Quantum Computing Inc as Chief Quantum Officer and a director.

In January 2024 the board appointed Dr. William McGann as chief executive officer, with co-founder Robert Liscouski becoming chairman; in April 2025 McGann announced his retirement effective May 12, 2025, and the board named Dr. Huang interim CEO and president.

The company’s principal executive offices are in Hoboken, New Jersey. Quantum Computing Inc rebranded its product line around integrated photonics, with a roadmap including the Dirac series of entropy quantum computers, a reservoir computing device for AI workloads, portable quantum random number generators, and quantum remote sensing instruments.

Technology

Integrated photonics and entropy quantum computing

Quantum Computing Inc focuses on integrated photonics—specifically thin-film lithium niobate (TFLN) and non-linear optical techniques—to manipulate light for computation. The firm’s approach to computation is termed “Entropy Quantum Computing” (EQC), which it positions as a practical, room-temperature method for solving combinatorial optimization tasks by exploiting photonic dynamics and entropy-based processes.

Its third-generation device, Dirac-3, is described by the company as a solver for discrete, non-convex optimization with all-to-all connectivity and low power consumption; education and developer documentation are provided for users.

Reservoir computing for AI

Beyond strictly quantum devices, Quantum Computing Inc develops quantum-inspired “reservoir computing” systems intended for time-series prediction and sequence-heavy AI tasks. The hardware is described as photonic-inspired and FPGA-based, packaged as the EmuCore edge device for applications such as forecasting, classification, and anomaly detection. In 2025, company engineers published benchmarking results on time-series forecasting using EmuCore at the International FLAIRS Conference.

Quantum random number generation (QRNG)

Quantum Computing Inc also develops quantum random number generators, marketed in portable form as uQRNG, to supply high-entropy randomness for cryptographic keys and secure systems. The company announced a reprogrammable, non-repeatable QRNG capability in 2023, citing compliance with standard statistical test batteries (e.g., NIST, Dieharder). QRNGs are considered a means to strengthen cryptographic systems by providing provably unpredictable entropy based on quantum processes.

Remote sensing and quantum imaging

Quantum Computing Inc’s sensing and imaging research includes quantum up-conversion and single-photon-sensitive methods. The company has showcased a Quantum Photonic Vibrometer (QPV) for remote vibration detection and non-line-of-sight sensing, as well as a quantum LiDAR prototype aimed at underwater operation and space-based atmospheric measurements. The firm’s technology pages describe single-photon-level imaging that reconstructs 3D structures through obscurants (e.g., tissue) and outline photonics-based approaches to denoising and signal extraction.

Academic work related to interaction-free and single-pixel quantum imaging with undetected photons—an area connected to the company’s research collaborators—has been documented in the literature.

Products

Dirac-3: a photonics-based entropy quantum computer positioned for combinatorial optimization and discrete, non-convex problems with all-to-all connectivity and low power usage.

EmuCore: an FPGA-based, photonic-inspired reservoir computer for time-series and sequence learning applications at the edge.

uQRNG: a portable quantum random number generator that can operate standalone or as an embedded entropy source for cryptographic systems and simulations.

Quantum Photonic Vibrometer (QPV): a remote sensing instrument for vibration detection, non-line-of-sight inspection, and quantum-enhanced signal retrieval.

Quantum LiDAR prototype: an underwater and space-sensing prototype featuring single-photon time-gated detection and frequency/phase-space tuning for enhanced information capture.

Operations and manufacturing

Quantum Computing Inc reports a photonic chip foundry initiative based on thin-film lithium niobate (TFLN) for integrated photonics fabrication. In May 2025, industry press reported QCi had opened a TFLN optical chip facility in Tempe, Arizona, to support its product roadmap. The company highlights “foundry services” alongside quantum machines on its website.

Customers, pilots, and partnerships

Quantum Computing Inc has announced multiple engagements in government, research, and enterprise contexts:

NASA LIDAR programs: In October 2024, the company said it received its fifth NASA project to develop quantum remote sensing technology to reduce the cost of spaceborne LiDAR imaging for climate research. In April 2025 the firm announced a NASA subcontract focused on denoising space-based LiDAR using Dirac-3 and photonic methods.

Automotive research: In April 2025, Quantum Computing Inc reported the sale and shipment of an EmuCore reservoir computer to a major automotive manufacturer for R&D use.

Academic orders: In 2025, industry aggregators reported a purchase order for QCi’s vibrometer from Delft University of Technology for LiDAR-related R&D.

Financial services: In July 2025, investor-relations feeds cited a purchase order from a top-five U.S. bank related to a quantum cybersecurity testbed.

Corporate affairs

Leadership and governance

Quantum Computing Inc’s leadership has included co-founder Robert Liscouski (chairman; formerly CEO), Dr. William J. McGann (CEO 2024–2025), and Dr. Yuping Huang (Chief Quantum Officer; interim CEO since May 2025). As of the company’s 2023 annual report, directors and executives collectively held approximately 31.8% of common stock; Dr. Huang beneficially owned about 25.0%, and Robert Liscouski about 3.5%.

In May 2025, QCi announced promotions of Milan Begliarbekov to chief operating officer and Pouya Dianat to chief revenue officer as part of a growth strategy across product and commercial functions.

Headquarters

The company lists its principal executive offices at 5 Marine View Plaza, Suite 214, Hoboken, New Jersey 07030, United States.

Financials

Quantum Computing Inc files with the U.S. Securities and Exchange Commission as a development-stage company with limited operating history. In its 2023 annual report, the company disclosed recurring losses, a working capital deficit, and “substantial doubt” about its ability to continue as a going concern absent additional financing, while pursuing commercialization of quantum photonic products. Investor-relations calendars indicated a scheduled release of second-quarter 2025 results on August 14, 2025, after market close, followed by a shareholder call.

Research and publications

QCi’s resource library cites peer-reviewed and preprint research on photonic reservoir computing, single-pixel pattern recognition with coherent non-linear optics, and FPGA-based reservoir implementations. The firm has emphasized an approach of “making photons work” for computing and sensing via integrated optics and non-linear processes, advocating room-temperature, low-power operation to reduce infrastructure costs relative to cryogenic quantum computers.

Criticism and reception

Analysts and industry observers have debated the commercial readiness of early quantum firms. In 2022, the short-seller research outlet Iceberg Research published a critical report questioning Quantum Computing Inc’s historical business transitions, customer quality, and prospects; the piece characterized the company as a speculative player and alleged related-party risks. The company has continued to emphasize its productization efforts and government/enterprise engagements thereafter. Earlier commentary from quantum industry press has also noted the company’s complex small-cap corporate history before its pivot to quantum computing under Liscouski’s leadership. As with many quantum technology companies, product claims are often accompanied by forward-looking statements and are subject to technical and market risks as disclosed in regulatory filings.
