New Delhi: India has taken another step towards building quantum-secure communication networks with the unveiling of 14 indigenous quantum products by the Centre for Development of Telematics (C-DOT), the telecom R&D centre under the Department of Telecommunications.
The products, developed in the areas of Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC), are designed to protect communication networks against emerging cybersecurity threats posed by advances in quantum computing.
The Quantum Product Series was unveiled during C-DOT’s 43rd Foundation Day celebrations in New Delhi in the presence of Union Minister for Communications Jyotiraditya M. Scindia, Minister of State for Communications Chandra Sekhar Pemmasani, Telecom Secretary Amit Agrawal and C-DOT CEO Rajkumar Upadhyay, among other dignitaries.

From Telecom to Defence, Products Target Multiple Applications
The Quantum Product Series has been designed for a wide range of applications across India’s communication ecosystem.
Its potential applications span:
- Enterprise
- Telecom
- Wireless
- Optical Networks
- Strategic Communications
- Defence
The portfolio combines two important approaches to quantum security:
Quantum Key Distribution (QKD) enables secure generation and distribution of encryption keys, while Post-Quantum Cryptography (PQC) uses cryptographic algorithms designed to withstand attacks from future quantum computers.
High-Speed Encryption for Critical Networks
Several of the newly unveiled products are designed to handle high-speed communication requirements.
Among them, Q-AMOGH supports up to 200 Gbps at the optical Layer 1 level, while Q-MAHASETU supports up to 40 Gbps for Layer 2/3 networks.
For strategic and defence requirements, C-DOT has developed products such as Q-VIKRAM and Q-PARAKRAM, each supporting throughput of up to 1 Gbps.
The products are intended to provide quantum-resistant protection for sensitive communications while supporting existing and next-generation network infrastructure.
Focus on Indigenous Research and Future-Ready Networks
The launch reflects C-DOT’s focus on converting indigenous telecom research and innovation into solutions that can be deployed across communication networks.
The products have been developed to address cybersecurity risks associated with the emergence of quantum computing and strengthen the resilience of India’s communication infrastructure.
A Quantum Product Series booklet was also launched during the event, bringing together details of C-DOT’s indigenous work in QKD and PQC.
Building India’s Quantum-Secure Communication Ecosystem
With quantum computing expected to pose new challenges to conventional cryptographic systems, C-DOT’s new portfolio is aimed at helping networks transition towards quantum-safe security.
The combination of QKD systems, PQC-based encryptors and specialised quantum communication components provides an indigenous technology base for developing secure communication solutions across existing and next-generation networks.
The initiative reinforces India’s push to develop secure, resilient and future-ready communication infrastructure while strengthening domestic capabilities in emerging quantum technologies.
