Key Details
At its 43rd Foundation Day on 31 August 2026, the Centre for Development of Telematics unveiled a 14-product indigenous quantum-security portfolio covering the generation of secure keys, protection of existing networks and critical components used in quantum communication.
Product group | Products and intended use |
|---|---|
Quantum Key Distribution | Q-AKSHAY CD generates and distributes quantum keys over fibre networks; Q-AKSHAY MDuses a measurement-device-independent protocol intended to reduce vulnerabilities associated with detection equipment. |
Quantum communication components | C-SPD, a single-photon detector, and C-RD, a wideband driver for optical modulators, are sub-components used to build quantum communication systems. |
Network and optical encryption | Q-SETU protects Layer 3 traffic at up to 80 Mbps; Q-MAHASETU supports Layer 2/3 networks at up to 40 Gbps; Q-AMOGH secures high-capacity optical links at up to 200 Gbps. |
Enterprise and access networks | Q-RAQSHAK targets enterprise networks, Q-VAAYU wireless point-to-point links and Q-VAJRA1000 existing access infrastructure such as GPON and wireless radios. |
Secure communications | Q-DARSHAN is a quantum-safe video IP phone, while Q-VACHAN is an in-line device intended to add quantum-resistant security to existing IP phones. |
Strategic applications | Q-VIKRAM and Q-PARAKRAM are defence-grade encryptors supporting up to 1 Gbps for sensitive and strategic communications. |
India Is Building Both Quantum and Post-Quantum Defences
The portfolio addresses the quantum-security challenge through two different approaches. QKD products use quantum principles to generate and exchange encryption keys, while most of the remaining products use post-quantum cryptography based on algorithms standardised by the US National Institute of Standards and Technology (NIST).
This distinction matters because QKD generally requires specialised communication infrastructure, whereas PQC can be incorporated into conventional software and network equipment. Developing both routes gives network operators options suited to different levels of security, cost and infrastructure readiness.
The Product Range Extends Beyond Research Prototypes
C-DOT has presented products for telecom access networks, enterprise systems, optical links, wireless connections, IP communications and defence applications. The range also includes components such as a single-photon detector and an RF driver, which could support other organisations developing quantum-communication systems.
The stated throughput—from 80 Mbps to 200 Gbps—suggests that the portfolio has been designed for substantially different operating environments, rather than as one standard solution for every network.
Existing Networks Are Part of the Transition Strategy
Several products are intended to introduce quantum-resistant protection without replacing the entire communication network. Q-VACHAN can sit alongside existing IP phones, while Q-VAJRA1000 is designed for integration with established access technologies.
Such upgrade paths could be important because India’s transition to quantum-safe communications will have to cover a large installed base. The practical value of the portfolio will therefore depend on interoperability, independent security evaluation and compatibility with equipment already used by telecom operators and public institutions.
Unveiling Products Is Not the Same as Securing Networks
The release identifies technologies and their intended applications, but does not disclose production capacity, procurement commitments, field-trial results, independent certification, pricing or deployment schedules. It therefore establishes the breadth of C-DOT’s indigenous portfolio, not the extent to which Indian communication networks have already become quantum-safe.
What Are QKD and Post-Quantum Cryptography?
Quantum Key Distribution (QKD) uses properties of quantum physics to generate and exchange encryption keys. Attempts to intercept the exchange can disturb the quantum signals and reveal possible eavesdropping.
Post-Quantum Cryptography (PQC) uses mathematical algorithms designed to resist attacks from both conventional and future quantum computers. Unlike QKD, it can often be introduced through upgrades to software or existing network equipment.
Policy Relevance
The next policy question is one of migration and assurance, not simply product availability. India will need to determine which networks should receive PQC upgrades first, where the additional infrastructure required for QKD is justified and how indigenous products will be tested before use in critical systems.
A credible transition would need to demonstrate:
Security assurance: independent evaluation against recognised cryptographic and telecom-security standards.
Interoperability: reliable operation across equipment supplied by different vendors and within existing public and private networks.
Prioritisation: early protection of information that must remain confidential for many years, including strategic, financial and critical-infrastructure data.
Deployment evidence: field trials, procurement and operational performance—not only the number of technologies unveiled.
Relevant Question for Policy Stakeholders: Which critical Indian communication networks should be prioritised for quantum-safe migration, and what certification and interoperability tests must the 14 products clear before large-scale deployment?
