What Rigetti Computing (RGTI)'s $8.4 Million India Quantum Order Means For Shareholders - Yahoo Finance

What Rigetti Computing (RGTI)'s $8.4 Million India Quantum Order Means For Shareholders Simply Wall St February 23, 2026 3 min read RGTI -0.29% Rigetti Computing previously announced an US$8.4 million order from India’s Centre for Development of Advanced Computing to deliver a 108-qubit quantum computer in Bengaluru, alongside plans to commercially launch its modular Cepheus-1-108Q system by late first quarter 2026. This contract underscores growing international demand for Rigetti’s on-premises quantum hardware and offers an early test of the company’s ability to scale complex systems for real-world research use. We’ll now examine how this Indian 108-qubit system order could influence Rigetti’s investment narrative around system sales and long-term adoption. Capitalize on the AI infrastructure supercycle with our selection of the 34 best 'picks and shovels' of the AI gold rush converting record-breaking demand into massive cash flow. Rigetti Computing Investment Narrative Recap To own Rigetti shares, you need to believe that its chiplet based superconducting roadmap can translate cutting edge hardware into paying system customers before cash burn and execution risk dominate the story. The US$8.4 million C DAC order in India supports that thesis by validating on premises system demand, but it does not change the near term reality of small revenue, high operating losses and reliance on a few large contracts as the key risk and catalyst. The Indian 108 qubit system ties directly into Rigetti’s Cepheus 1 108Q roadmap, which targets commercial launch by late first quarter 2026. That timing sits alongside other catalysts such as the three year US$5.8 million AFRL networking contract and growing Novera deployments, which together could start to shift the mix from mainly research style work toward more recurring system sales and usage based revenue. Yet against the excitement around India’s order, investors should also be aware that...

Faster-Than-Light Photons May Not Break the Rules of Cause and Effect

Scientists are increasingly investigating the implications of superluminal photon propagation arising from the Drummond-Hathrell effective action in quantum electrodynamics. Madhukar Deb, Jay Desai, and Diptimoy Ghosh, all from the Department of Physics at the Indian Institute of Science, Education and Research, Pune, have revisited the question of causality in curved spacetime using novel diagnostics. Their research establishes conditions under which this seemingly superluminal behaviour does not lead to the formation of closed causal curves, addressing a conceptually nontrivial problem in theoretical physics. By analysing both the global causal structure and applying flat-spacetime analyticity bounds to the photon commutator, the authors demonstrate causal consistency within the regime of validity of the Drummond-Hathrell effective theory for scenarios including circular photon orbits and two-black-hole geometries. The study centres on understanding whether the observed superluminality, where photons appear to travel faster than light, genuinely disrupts the established order of events. The investigation employs two independent methods to assess causal consistency. First, the team analysed the global causal structure of the effective optical metric governing photon propagation, establishing conditions under which it remains stably causal and prevents the formation of closed timelike curves. This analysis was performed for both a circular photon orbit within the Schwarzschild geometry and a linear trajectory in a two-black-hole spacetime. Secondly, researchers examined microcausality from a quantum field-theoretic perspective, treating gravity as a fixed, Lorentz-breaking field and applying flat-spacetime analyticity bounds to the photon commutator within the geometric-optics regime of the effective field theory. For the representative examples of a circular orbit in Schwarzschild spacetime and a linear trajectory in a two-black-hole geometry, the findings indicate

Quantum computing Indias ticket to leading role in global tech space: Chandrababu Naidu - Mintquantum-computing

Quantum computing Indias ticket to leading role in global tech space: Chandrababu Naidu - Mint

Amaravati, Feb 8 (PTI) India is poised to become a leading player in quantum technology, which could prove to be a game-changer for the IT sector and the wider economy, Andhra Pradesh Chief Minister N Chandrababu Naidu said on Sunday. The Quantum Valley initiative launched in Andhra Pradesh is set to usher in the next wave of the information technology (IT) revolution in the country, Naidu said in an interview with PTI Videos, emphasising that it would position India as a hardware-and-manufacturing powerhouse, in addition to being a software-and-services hub. "Technology is mature now. AI is a reality. Real-time data collection is a reality. The next level is quantum computing as it has unlimited capabilities. As of today, this is the fastest, the father of all technologies or, you can say, the mother of all technologies," he said. "Only a few countries have taken the lead in quantum technology and we are one of them. The Government of India has announced the quantum mission. Now, we are establishing it (Quantum Valley) here. With that, our people are ready to produce quantum computers and get into manufacturing now," Naidu said. Acknowledging that MoUs and investment pledges often make headlines but do not eventually lead to enough action on the ground, the chief minister said he is working on improving that conversion rate and putting in place safeguards to ensure that non-serious players are weeded out. "Earlier, I used to say ease of doing business. Now, I am going for speed of doing business. Any investor, when he invests, he is expecting returns. Then only will he survive. If his project is delayed abnormally, then naturally it will not be viable. All hurdles I want to remove. I am introducing escrow accounts for all benefits or subsidies. "I have committed something for you, year by year. I will give you online with an escrow account. You do not come to me. This is where I wanted to promote self-discipline and also government regulation," Naidu said.

Quantum ResearchBlogBreaking ground on India’s quantum futureConstruction begins on India’s Quantum Valley Tech Park as the nation grows its quantum education initiatives and prepares for its first IBM quantum computer.Date7 Feb 2026AuthorsAnupama RayRobert DavisTopicsCommunityNetworkShare this blogBlog summary: India has begun construction on the Quantum Valley Tech Park in Amaravati, the future home of the country’s first IBM quantum computer. The ground breaking arrives as a nationwide push to grow India’s quantum workforce is accelerating. For example, one free online quantum computing course co-created by IBM has already surpassed 168,000 enrollments for 2026. While construction is under way, tech park members will have access to IBM quantum computers over the cloud thanks to a collaboration between IBM and India’s Tata Consultancy Services (TCS). India takes a bold step toward scaling its quantum workforce this week as the Government of Andhra Pradesh, a State in southern India, begins construction on Quantum Valley Tech Park in the capital city of Amaravati. Quantum Valley Tech Park will soon host India’s first IBM quantum computer, and tech park members already enjoy access to IBM’s cloud-based quantum computers thanks to a partnership between IBM and India’s Tata Consultancy Services (TCS), first announced last spring. These initiatives are bringing renewed national focus to India’s ongoing efforts in quantum education and workforce development. According to a report published by the Government of India’s apex policy think tank NITI Aayog (National Institution for Transforming India) in December, India will need to train approximately 100,000 quantum developers to secure its place as a quantum computing leader in the 2030s, a decade that will be shaped by the emergence of large-scale, fault-tolerant quantum computing. The message is clear: India’s long-term competitiveness in quantum computing will hinge on the strength of its talent pipeline. “With Quantum

Quantum Kernel Methods Show Competitive Radar Classification with 133-Qubit IBM Processorquantum-computing

Quantum Kernel Methods Show Competitive Radar Classification with 133-Qubit IBM Processor

Researchers are increasingly exploring quantum machine learning for complex signal processing tasks, and this study investigates the practical application of quantum kernel methods to radar micro-Doppler classification. Vikas Agnihotri, Jasleen Kaur from the National Institute of Technology, Rourkela, and Sarvagya Kaushik from the Indian Institute of Technology, Dhanbad, et al., demonstrate a Quantum Support Vector Machine (QSVM) capable of classifying aerial targets from radar signatures, even with the limitations of current noisy intermediate-scale quantum (NISQ) hardware. By combining classical feature extraction with quantum kernel encoding and evaluating performance on both simulators and IBM quantum processors, this work offers a crucial assessment of the feasibility and challenges of deploying quantum algorithms for real-world radar applications, potentially paving the way for more efficient and accurate target recognition systems. The research team extracted classical features and reduced their dimensionality using Principal Component Analysis (PCA) to facilitate efficient quantum encoding. Reduced feature vectors were then embedded into a quantum kernel-induced feature space via a fully entangled ZZFeatureMap before classification using a kernel-based QSVM. This reduction in dimensionality is crucial for efficient quantum processing and encoding of complex radar signals. The study systematically investigated the impact of noise, decoherence, and measurement shot count on quantum kernel estimation, identifying improved stability and fidelity on the newer Heron r2 architecture. By mapping micro-Doppler patterns into an expanded quantum state space, the classifier can more easily separate subtle differences in target dynamics. This work provides a comprehensive comparison between simulator-based and hardware-based QSVM implementations, highlighting both the feasibility and current limitations of deploying quantum kernel methods for practical radar signal class

Picoseconds on Demand: Tiqker Optical Atomic Clock Cruises the Quantum Corridorquantum-computing

Picoseconds on Demand: Tiqker Optical Atomic Clock Cruises the Quantum Corridor

Right on Time: Bringing Picosecond Precision to Live Networks   I’m excited to finally get to share that Infleqtion, together with Quantum Corridor, completed a successful live demonstration of a high-performance quantum timing solution for critical networked infrastructure. We ran the test across 22 kilometers of live urban fiber, between Chicago’s ORD10 Data Center and the Digital Crossroad Data Center in Hammond, Indiana and back. Tiqker, Infleqtion’s 3U rack-mounted optical atomic clock, empowered with the White Rabbit time transfer protocol, held picosecond-level synchronization. The system outperformed traditional rack references and GPS-derived time on the short-to-medium timescales that matter for modern network data systems.  Figure 1: Tiqker installation in Hammond, Indiana  This matters because the future  depends on timing that actually matches how fast hardware performs. What we showed is that deterministic, picosecond-class timing can be delivered over existing fiber in real conditions, aligning timing precision with the physical timescales of contemporary optical network hardware. We ran the test in the real world  – these aren’t lab numbers.   Figure 2: Tiqker units, White Rabbit switches and time distribution installed at Digital Crossroads.  Where Timing Is Everything  The potential applications for Tiqker optical atomic clocks are wide-ranging. In data centers and distributed computing, picosecond timing enables precise packet alignment, cutting time buffers and improving throughput. Emerging telecommunications systems using time-sensitive networking require deterministic time, while financial customers gain more accurate timestamps for trading, audit, and model training data.

Infleqtion and Quantum Corridor Demonstrate GPS-Free Quantum Timing Solution for Critical Network Infrastructure

Live test between Chicago and Northwest Indiana shows up to 40X improvement over GPS for keeping digital systems synchronized Infleqtion, a global leader in quantum sensing and quantum computing powered by neutral-atom technology, today announced a successful live demonstration with Quantum Corridor showing how critical digital infrastructure can stay precisely synchronized without relying on GPS. Quantum Corridor is a quantum-safe, ultra-fast, and highly secure fiber-optic network in the Midwest enabling next-generation communication. The demonstration was conducted across 21.8 kilometers of live urban fiber between Chicago’s ORD10 Data Center (350 Cermak) and the Digital Crossroad Data Center (100 Digital Crossroad Drive) in Hammond, IN. The announcement follows Infleqtion’s plans to go public through a merger with Churchill Capital Corp X (NASDAQ: CCCX). Modern digital systems, from data centers and financial trading platforms to AI networks and defense systems, depend on precise timing to function properly. Today, most rely on GPS satellites to stay synchronized. But GPS signals can be jammed, spoofed, or disrupted, creating a single point of failure for critical infrastructure. As these systems grow more complex and handle more data, they need timing that is more precise, more stable, and more secure than GPS alone can provide. “As digital infrastructure scales, relying on a single source of time is a growing risk,” said Pranav Gokhale, CTO, Infleqtion. “This demonstration shows that quantum grade timing can be delivered over existing fiber, giving operators a more precise and resilient alternative to GPS for keeping critical systems in sync.” What Was Demonstrated The demonstration leveraged Infleqtion’s Tiqker, a rugged, rack mounted quantum optical atomic clock designed for deployment in operational environments. Operating on Quantum Corridor’s in situ dark fiber, the system maintained picosecond level synchronization while continuing to perform th

Quantum Machines Becomes Sixth Tenant at Illinois Quantum Parkquantum-computing

Quantum Machines Becomes Sixth Tenant at Illinois Quantum Park

Insider Brief Quantum Machines, an Israeli quantum software company, plans to establish a lab at the Illinois Quantum and Microelectronics Park on Chicago’s South Side, becoming the sixth tenant to commit to the state-backed research campus. The company develops control software that links quantum computers with classical systems and says its technology is used by more than half of companies building quantum computers worldwide. Illinois has committed $500 million to the park as part of a broader effort to attract quantum companies, research activity and investment and position the state as a leading U.S. quantum hub. Aerial view of the former U.S. Steel South Works site (IQMP) Quantum Machines, quantum software company from Israel, plans to expand into Chicago, adding another anchor tenant to Illinois’ push to build a nationally prominent quantum technology hub. According to Crain’s Chicago Business, the company expects to establish a presence at the Illinois Quantum and Microelectronics Park, a 138-acre research campus under construction on the former U.S. Steel South Works site along Lake Michigan near the Indiana border. The company would become the sixth tenant to publicly commit to the park, which is positioned as the centerpiece of Illinois’ quantum strategy. Quantum Machines develops software that controls quantum computers and connects them with conventional computing systems. While quantum computers rely on the rules of quantum physics rather than classical electronics, they still require traditional hardware and software to operate, manage data and run hybrid workloads. Quantum Machines’ tools sit at that interface, coordinating how quantum processors execute instructions and exchange information with classical machines. The strength of the Illinois ecosystem is one of the reasons the company established a base in Chicago, company executives told Crain’s Chicago Business. “While QM has strong partnerships across the U.S. quantum ecosystem, the decision to
