Bengaluru-based deep-tech startup Pramatra Space is developing indigenous chip-based quantum communication technology designed to protect satellite networks, defence communications, financial institutions, and critical digital infrastructure against emerging cybersecurity threats. The company’s approach combines quantum key distribution (QKD), integrated photonics, and post-quantum cryptography to create secure communication systems for both space-based and terrestrial applications.
Founded in 2023, Pramatra Space has made significant progress in developing its proprietary quantum key distribution chip. According to an update published on 13 October 2026, the startup has completed the third tape-out of its chip design, filed its final patent application, and begun testing its latest hardware.
The company is preparing for an in-space technology demonstration in 2027, followed by its first planned mission in 2028. Its development programme represents an emerging Indian effort to build quantum-secure communication technologies that can operate across satellites, ground stations, telecommunications networks, and other critical infrastructure.
Pramatra Space Completes Third Quantum Chip Tape-Out
Pramatra Space has reached an important milestone in the development of its integrated photonics-based quantum key distribution technology.
Founder and CEO Richa Hukumchand confirmed that the company had progressed from two chip tape-outs to three, with the latest chips undergoing testing.
In semiconductor development, a tape-out marks the completion of a chip’s design before it enters the fabrication process. It represents an important engineering milestone because developers can subsequently evaluate manufactured chips against their intended specifications.
The startup has also submitted its final patent application, advancing the protection of its intellectual property associated with quantum communication technology.
Pramatra’s system uses integrated photonics, a technology that manipulates light through miniature optical components fabricated on semiconductor chips. This approach can significantly reduce the size of equipment traditionally required for specialised optical communication systems.
Compact photonic hardware is particularly important for satellite applications, where available space, electrical power, and payload weight are limited.
Quantum Key Distribution for Secure Communication
Quantum Key Distribution uses principles of quantum physics to help communicating parties establish shared secret encryption keys.
Unlike conventional key-establishment mechanisms that rely primarily on mathematical computational difficulty, QKD uses quantum states of light to distribute key information.
Attempts to measure or interfere with these quantum states can introduce detectable disturbances, helping legitimate users identify possible interception.
The technology does not eliminate every cybersecurity threat. Secure implementation still requires authentication, properly designed hardware, trusted software, and effective management of encryption keys.
Pramatra Space is developing technology that combines the physical security properties of QKD with established and emerging cryptographic methods.
Its objective is to provide an additional security layer for organisations that need to protect sensitive information over extended periods.
Combining Quantum Key Distribution with Post-Quantum Cryptography
An important feature of Pramatra Space’s technology roadmap is its hybrid approach to quantum security.
The company is combining Quantum Key Distribution with Post-Quantum Cryptography (PQC), which uses mathematical algorithms designed to resist attacks from future quantum computers.
Although both technologies address quantum-era security challenges, they operate differently.
QKD focuses on distributing secret keys using quantum communication techniques. Post-quantum cryptography provides cryptographic algorithms that can be implemented through conventional computing and communication infrastructure.
According to Hukumchand, feedback from the defence sector encouraged the company to pursue a hybrid architecture.
The approach allows quantum key distribution to contribute to secure key establishment while post-quantum cryptographic mechanisms support additional requirements such as authentication.
Combining these technologies could help organisations strengthen communication security without relying exclusively on a single protection mechanism.
Satellite-Based Quantum Security for Long-Distance Networks
Pramatra Space originally concentrated on developing quantum key distribution systems for satellite applications.
Terrestrial QKD systems commonly transmit quantum signals through optical fibre or free-space optical links. Fibre-based systems face transmission losses that can limit the distance over which quantum keys can be distributed without additional infrastructure.
Satellite-based QKD offers a potential solution by transmitting quantum signals between spacecraft and optical ground stations.
Pramatra’s proposed architecture incorporates compact photonic chips into satellite payloads, allowing quantum communication technology to operate from low Earth orbit.
The company intends to combine these space-based capabilities with terrestrial systems to establish secure communication links over greater geographical distances.
Such systems could eventually support organisations requiring secure communication between widely separated facilities, including financial institutions, telecommunications operators, and critical infrastructure providers.
Qimaya and QimayaSat: Indigenous Quantum Security Platforms
Pramatra Space is developing two complementary quantum communication products, Qimaya and QimayaSat, to address security requirements across terrestrial and satellite networks. Qimaya is a terrestrial hardware security module designed to support both optical fibre and free-space quantum key distribution. Combining these capabilities within a single device could simplify the deployment of quantum-secure communication infrastructure.
QimayaSat is the company’s compact satellite payload intended for deployment in low Earth orbit. It incorporates chip-scale quantum communication technology to distribute encryption keys between spacecraft and ground-based infrastructure.
The company’s product information, included in the government-backed Bharat Innovates 2026 programme, describes QimayaSat as a system designed to reduce equipment size and cost while improving key-generation performance compared with conventional architectures. These are development targets rather than independently established operational performance figures.
Pramatra is also building a Key Management System that can integrate quantum-derived keys with existing enterprise infrastructure. The platform is designed around ETSI QKD 014 interface specifications, allowing organisations to access key-management services through standardised software interfaces.
Together, these technologies form the foundation of the company’s proposed integrated quantum-security platform.
Applications in Defence, Telecommunications and Drone Networks
Pramatra Space is exploring applications beyond its original satellite communication programme.
The compact nature of its photonic technology has attracted interest in terrestrial communication networks, particularly applications where conventional quantum communication equipment would be difficult to install.
One potential application involves secure optical communication between telecommunications towers. Such links could provide an additional security mechanism for sensitive information exchanged between network infrastructure facilities.
The company is also examining possible applications in communications between unmanned aerial vehicles and their ground control stations.
Military drones rely on communication links for command transmission, telemetry, navigation information, and other mission-related data. Securing these links is increasingly important as unmanned systems become integral to modern defence operations.
Pramatra’s proposed technology could eventually provide additional key-distribution capabilities for specialised military communication networks.
The company has confirmed that discussions concerning terrestrial pilot applications are underway. These activities remain exploratory, and operational deployment in military drone systems has not been announced.
Quantum Security Technology for Data Centres
Pramatra Space is developing a quantum-security product intended for data-centre applications.
Modern data centres support financial transactions, government services, enterprise computing, artificial intelligence, and other activities that involve significant volumes of sensitive information.
Protecting the confidentiality and integrity of these systems is essential for organisations handling valuable digital assets.
The company’s planned security architecture combines specialised quantum hardware with a software platform designed to manage cryptographic keys.
This approach could allow enterprises to incorporate quantum-based key distribution into their existing security environments.
Pramatra’s data-centre product remains under development, while the company continues working on the hardware and software components required for practical deployment.
Collaboration with Japanese Ground Station Company Infostellar
Pramatra Space is working with Japanese ground station company Infostellar Inc. to explore additional optical ground station infrastructure and requirements for secure end-to-end communication.
Optical ground stations are essential components of satellite quantum communication systems because they receive and transmit optical signals between spacecraft and terrestrial networks.
Successful operation requires precise tracking, alignment, atmospheric compensation, and integration with ground-based security infrastructure.
The collaboration is focused on examining ground station requirements and extending the company’s understanding of the infrastructure needed for satellite-based quantum key distribution.
International technical cooperation in specialised areas such as optical communication can support the development of Indian space technology and its integration with global satellite infrastructure.
Space Demonstration Planned for 2027
Pramatra Space is targeting 2027 for its first in-space technology demonstration, followed by a planned mission in 2028.
The company is working with approximately three satellite companies as it develops the hardware and integration requirements for these activities.
Space qualification represents a significant engineering challenge for photonic and electronic equipment.
Satellite payloads must withstand launch vibration, thermal variations, radiation exposure, and other environmental conditions while maintaining reliable performance.
For quantum communication technology, maintaining precise optical alignment and dependable photon transmission adds further complexity.
The proposed demonstration will provide an opportunity to evaluate the technology under space operating conditions.
Pramatra’s reported testing and integration activities represent progress towards this objective, while successful orbital operation remains a future milestone.
