WHAT IS QUANTUM ENTANGLEMENT

Quantum entanglement is the phenomenon wherein the quantum state of each particle in a group cannot be described independently of the state of the others, even when the particles are separated by a large distance.

WHAT IS QUANTUM KEY DISTRIBUTION (QKD)

Quantum Key Distribution (QKD) is a highly secure communication method that uses quantum mechanics, especially the properties of photons, to share secret cryptographic keys and detect any eavesdropping attempts.

Unlike traditional encryption based on mathematical complexity, QKD relies on the fundamental laws of physics to provide “unconditional security”.

Why Quantum Entanglement Matters
Advantage Explanation
Stronger Security More secure than traditional “prepare-and-measure” QKD methods.
Eavesdropping Detection Any interception can be detected because the quantum state collapses if disturbed.
Device-Independent Security Offers security even when hardware is imperfect or potentially tampered with.
PT Facts
  • QKD: Used to create secure cryptographic keys, not to directly transmit the full message.
  • Quantum Communication: Useful for defence, banking, strategic communication, and critical infrastructure.

Naval Anti-Ship Missile (NASM-SR)

On 25th February 2025, the Defence Research and Development Organisation (DRDO) and the Indian Navy successfully conducted flight trials of the Naval Anti-Ship Missile-Short Range (NASM-SR).

The successful trials demonstrated advanced targeting, guidance, and retargeting capabilities for modern naval warfare operations.

Key Features of NASM-SR
Feature Description
Missile Type A short-range anti-ship missile designed for naval strike missions.
Man-in-Loop System Allows in-flight retargeting through a high-bandwidth two-way datalink transmitting live images to the pilot.
Guidance Seeker Equipped with an Indigenous Imaging Infra-Red (IIR) Seeker for precise terminal guidance.
Lock-on Mode Fired in Bearing-only Lock-on after launch mode, initially targeting a large object before shifting to a hidden smaller target.
Operational Capability Enhances naval precision strike capability against enemy surface vessels.
Guidance and Propulsion Systems
System Details
Mid-Course Guidance Uses an indigenous Fiber Optic Gyroscope-based INS and Radio Altimeter.
Avionics Support Supported by an integrated avionics module and electro-mechanical actuators.
Propulsion System Powered by a solid propulsion system with an ejectable booster and long-burn sustainer.
Development Model Developed by multiple DRDO labs under the Development cum Production Partner (DcPP) model.
Trial Outcome Successfully met all mission objectives during the flight trials.
PT Facts
  • NASM-SR: Stands for Naval Anti-Ship Missile-Short Range.
  • Man-in-Loop: Allows human intervention or retargeting during missile flight.
  • IIR Seeker: Uses infrared imaging for target detection and terminal guidance.
  • Anti-Ship Missiles: Designed to target enemy surface vessels during naval combat operations.
