QpiAI – A Tech Magician

Without a much ado lets first understand, Quantum Computing

Quantum computing is a cutting-edge field of computing that uses principles of quantum mechanics to process information. Unlike classical computers, which use bits (0’s and 1’s), quantum computers use qubits, which can be 0, 1, or both at the same time (as per  a concept called superposition).

More Concepts

1. Qubits
   • The basic unit of quantum information.
   • Can exist in multiple states simultaneously (unlike classical bits).
2. Superposition
   • A qubit can be in a state of 0, 1, or both at once.
   • Enables quantum computers to process many possibilities simultaneously.
3. Entanglement
   • When qubits become linked, the state of one instantly affects the other, no matter the distance.
   • Used for powerful correlations in quantum calculations.
4. Quantum Interference
   • Allows for amplifying correct solutions and canceling incorrect ones in computations.

What Can Quantum Computers Do?

• Factor large numbers (important for cryptography)
• Simulate molecules (useful in drug discovery and chemistry)
• Optimize complex systems (logistics, finance, AI)

Solve problems that are infeasible for classical computers

India’s First Full-Stack Quantum Computer by QpiAI

On April 14, 2025, Bengaluru-based startup QpiAI, which was selected under the National Quantum Mission (NQM), unveiled India’s first full-stack quantum computer named QpiAI-Indus. This 25-qubit superconducting system integrates quantum hardware, a hybrid quantum-high-performance computing software stack, and AI-driven optimization tools. The launch aligns with NQM’s objectives to advance domestic quantum capabilities and establish intermediate-scale infrastructure.

Its India’s First Full-Stack 25-Qubit Superconducting Quantum Computer Under National Quantum Mission

QpiAI, a Bangalore-based startup selected under India’s National Quantum Mission (NQM), has launched a 25-qubit superconducting quantum computer, marking the country’s first full-stack quantum system. The platform, named QpiAI-Indus, integrates superconducting qubit hardware, a hybrid Quantum-HPC software stack, and AI-driven optimization tools. The announcement was made on World Quantum Day, April 14, 2025, and supports NQM goals of advancing domestic quantum capabilities and establishing intermediate-scale infrastructure.

The system combines a cryogenic control environment with proprietary software tools including QpiAISaaS and QpiAI-Opt, designed to support quantum-classical workflows across sectors such as drug discovery, materials science, logistics, and climate modeling. These tools facilitate access to quantum computing through a hybrid interface that applies machine learning techniques to guide quantum optimization algorithms. The company has filed 11 patents and is generating early-stage revenue through software licensing.

The launch aligns with India’s broader NQM roadmap, which targets the development of 20–50 qubit systems in the near term and scalable architectures over the coming decade. QpiAI is one of eight startups supported by the initiative, which is coordinated by the Department of Science and Technology (DST) and backed by a total investment of ₹6003.65 crore (~USD 730 million). The development contributes to the national strategy of fostering domestic innovation, public-private collaboration, and a quantum-skilled workforce.
