Quantum Computing Inc

Quantum Computing Inc. is presenting an integrated quantum security platform at the ECOC Exhibition in 2026. The system combines quantum key distribution with hardware based quantum identity authentication for secure communications, built on the company's patented, award winning technology and shown in a live deployment style demonstration. The launch sits within Quantum Computing's broader effort to turn lab grade quantum technology into practical tools for secure data transmission, linking its photonics, patents and vertically integrated manufacturing to a complete security stack that network operators could test against incumbents such as Toshiba's QKD offerings or efforts from ID Quantique and similar peers. The company operates as a US based integrated photonics business supplying quantum machines to commercial and government clients, and the article cites a fair value of $18.33 for Quantum Computing. The bear case remains, as the business is spending heavily ahead of large-scale demand and turning the demo into repeatable, multi-site contracts is still unproven.

D-Wave Quantum has executed a definitive agreement with the U.S. Department of Commerce, based on its previously announced Letter of Intent, giving it access to up to $100 million in funding under the U.S. CHIPS and Science Act to accelerate research and development of its annealing and gate-model quantum systems. NTT DOCOMO, Japan's largest mobile operator, deployed a second D-Wave-powered quantum computing application in production, which cut location-registration signals generated when devices crossed tracking-area-list boundaries by 65.3% at the daily peak and reduced paging signals by 7.0%. D-Wave was also awarded up to CAD $300,000 from the National Research Council of Canada's Applied Quantum Computing Challenge program to advance annealing quantum computing software for commercial applications, and AT&T agreed to expand its use of D-Wave's quantum computing technology to address complex optimization challenges across its network operations. Separately, Rigetti plans to partner with HPE and Pittsburgh Supercomputing Center to build the TangleLab supercomputing testbed, delivering a 9-qubit Novera system to the testbed, which is funded by a $5 million National Science Foundation grant, while Quantum Computing signed a three-year framework agreement with Hamad Bin Khalifa University in Qatar covering quantum computing, quantum sensing and quantum communications. Over the past year, QBTS shares have lost 36.2% compared with the broader Internet Software industry's 5.8% decline, and the stock trades at a forward 12-month price-to-sales ratio of 93.25X versus the industry average of 4.40X.

Rigetti Computing said in its latest technology update that the biggest challenge in its quantum roadmap is no longer adding more qubits but improving the performance of its flagship 108-qubit Cepheus system. During the second quarter of 2026 earnings call, management acknowledged that coherence time has become the primary bottleneck limiting two-qubit gate fidelity, even as Cepheus-1-108Q stands among only three generally available gate-based quantum computers with more than 100 qubits. The system currently operates with coherence times of roughly 25-30 microseconds, a level that constrains the reliability of quantum operations. Rigetti is directing engineering efforts toward chip redesigns, fabrication process improvements and new materials, including tantalum-capped superconducting contacts, and management expects these initiatives to gradually double or even triple coherence times over the next several years. In peer updates, Quantum Computing Inc. signed a three-year Framework Agreement with Hamad Bin Khalifa University in Qatar covering quantum computing, sensing and communications, while IonQ secured an $8.18 million commercial agreement with Congruity360 to integrate quantum-safe networking into its enterprise data management platform.

Quantum Computing Inc. announced it will showcase, for the first time, an integrated quantum security platform combining encryption and authentication in a single solution at the ECOC Exhibition 2026, held September 21–23 at FYCMA in Málaga, Spain. At Booth #1436, the company will demonstrate live quantum communication solutions using time-frequency and polarization-based approaches, pairing quantum key distribution with hardware-based Quantum Identity Authentication. The platform combines high-dimensional quantum key distribution, direct entanglement verification, Quantum Identity Authentication, and integrated key management in a telecom-compatible architecture, and is based on QCi's patented invention recognized with the 44th Edison Patent Award, presented to Dr. Yuping Huang and Dr. Lac Nguyen. QCi will also present at the ECOC Product Focus Theatre on Wednesday, September 23, from 14:50 to 15:10, in a session titled "The Quantum Secure Solution: Quantum-authenticated communications for broad applications in security," delivered by Massimo Di Blasio, Director, Product Line Management/Business Development. Chief Technology Officer Yong Meng Sua said the demonstrations give the telecom industry a firsthand look at how quantum technologies can strengthen the security of tomorrow's communications.
