Context:

A new study from researchers at the Raman Research Institute (RRI) reveals that the intraparticle form of entanglement can also emerge from noise itself.

QUANTUM NOISE

What is "quantum"?

It refers to the smallest possible units of energy or matter. In the quantum world, particles like electrons and photons behave strangely, which can be harnessed to create powerful new technologies.

What is quantum entanglement?

It is a phenomenon where two or more quantum particles become linked in such a way that they share the same fate, no matter how far apart they are.
Albert Einstein famously called this "spooky action at a distance."

What is Quantum Noise?

Quantum noise refers to random disturbances or interference in quantum systems.

This prevents quantum technologies from working reliably, hindering progress in building super-secure communication networks and ultra-powerful computers.

What are the main sources of quantum noise?

Environmental Factors: Temperature, Vibrations, Electromagnetic Fields, Cosmic Rays
Internal Factors: Material Defects, Manufacturing Imperfections, Interactions within the system

Earlier, scientists believed quantum noise was purely destructive. When quantum particles interact with their surroundings, they lose their quantum properties.

Recently, researchers at India's Raman Research Institute (RRI), collaborating with the University of Calgary in Canada, discovered that certain types of Quantum noise can help generate or even revive a special kind of entanglement.

The discovery will help to build more robust and efficient quantum systems that can tolerate or even benefit from noise, which could accelerate the development of practical quantum technologies.

Frequently Asked Questions (FAQs)

Quantum noise is like unwanted interference or static that messes up the super-sensitive tiny particles used in quantum computers and communication, causing errors.

NISQ stands for Noisy Intermediate-Scale Quantum, referring to current quantum computers that are powerful but still significantly affected by noise.

Overcoming quantum noise is vital for India to build unbreakable quantum-encrypted communication systems, safeguarding critical national data and defense networks.
