Noise Effect on Quantum Entanglement:
Scientists from Raman Research Institute (RRI), IISc Bangalore, IISER Kolkata have found that quantum noise can sometimes enhance, revive, or even create entanglement, challenging earlier beliefs that it only disrupts quantum systems.
- Quantum entanglement refers to a phenomenon in quantum mechanics where two or more particles become interlinked, such that the state of one particle instantly determines the state of the other, regardless of the distance.
- It forms the basis of advanced technologies like quantum computing, quantum cryptography, and quantum communication,
- Types of Quantum Entanglement:
- Intraparticle entanglement, where different properties (e.g., spin and path) of a single particle are entangled.
- Interparticle entanglement, the more common form, involving entanglement between separate particles.
- Quantum noise refers to random disturbances arising from a system’s interaction with its environment, often leading to loss of coherence (decoherence) and degradation of quantum properties like entanglement.
