In a pivotal move, DRDO’s RCI opens its doors to private Indian companies for co-developing quantum-based avionic sensors—the critical enablers of sixth-generation air combat.
Ushering in the Sixth-Generation Revolution
India’s defence ecosystem is now setting the stage for a quantum transformation. The Research Centre Imarat (RCI), a premier DRDO lab in Hyderabad, has initiated a landmark move—inviting Indian industry and start-ups to co-develop quantum avionic sensors for future combat platforms.
- These sensors are expected to be core components of sixth-generation fighter aircraft, enabling operations in GPS-denied, jammed, and stealth-saturated battlespaces.
- The move reflects a radical shift from DRDO’s traditional closed-loop development model to a collaborative, innovation-driven partnership approach.
The Quantum Sensor Triad
RCI is targeting three disruptive quantum technologies that will define next-gen air dominance:
- Quantum Inertial Navigation
- Provides centimetre-level accuracy without relying on GPS.
- Critical for fly-through-denial operations in EW-heavy theatres like the Himalayas and Arabian Sea.
- Quantum Magnetometry
- Detects magnetic anomalies with ultra-high sensitivity.
- Potential applications range from submarine detection to underground IED spotting—from the air.
- Quantum Radar / Lidar
- Uses entangled photons to detect stealth aircraft.
- Functions even against platforms designed to scatter or absorb traditional radar waves.
Lab Breakthroughs & Engineering Challenges
RCI has already achieved lab-scale demonstrations of quantum accelerometers and magnetometers that outperform current-generation ring-laser and fibre-optic gyroscopes used in platforms like Tejas and Rafale.
- The next challenge is hardening these fragile systems into flight-worthy packages.
- Key hurdles include miniaturisation, vibration resilience, thermal stability, and long-term coherence in the harsh Mach 2+, 9g environment of combat jets.
Open Call for Indian Industry
To overcome these engineering challenges, RCI has opened the development programme to private sector innovation under the Technology Development Fund (TDF) and iDEX (Innovations for Defence Excellence) schemes.
- Expertise sought includes:
- Ultra-high vacuum systems
- Photonic integrated circuits
- Cryogenic cooling
- Single-photon detection
- Cold-atom interferometry
- Companies in silicon photonics, diamond NV-centre materials, and quantum optics have already been approached.
- The aim is to deliver flight-qualified sensor modules for integration into the AMCA Mk2 and classified sixth-gen platforms.
Strategic Autonomy and Industrial Promise
This initiative could redefine India’s position in global air combat innovation. Quantum-based sensors are not just enhancements—they are foundational technologies for networked, autonomous, and stealth-penetrating warfare.
- Quantum INS means jam-proof, spoof-proof navigation, vital in contested zones.
- Quantum magnetometers allow real-time subsurface scanning from fighters.
- Quantum radar promises a stealth-neutralizing capability—a game-changer in the Indo-Pacific theatre.
Most critically, RCI is offering up to 90% development funding, full know-why transfer, and a defined production pathway—but with one strict caveat:
All tech must be Indian—from chip to sensor to airframe.
RCI has invited Indian start-ups and private firms to co-develop quantum avionic sensors for next-gen fighter aircraft. These breakthrough systems—quantum navigation, radar, and magnetometers—will enable combat superiority in jammed and stealth-dominated environments. Integration targets include AMCA Mk2 and sixth-gen platforms.
