Indian Scientists Find Way to Make Quantum Entanglement Last Longer
What Happened
Scientists at the Raman Research Institute (RRI) in Bengaluru have developed a technique to prolong quantum entanglement using a precisely timed“flip operation.” The method can delay, prevent, or even accelerate the phenomenon known as“entanglement sudden death,” where entangled particles lose their quantum connection due to environmental interactions. The research, conducted with the University of Calgary and Louisiana State University, was published in Physical Review A and supported by India’s National Quantum Mission.
Key Takeaways
Quantum entanglement is fundamental to quantum computers and quantum communication systems, but it is notoriously fragile. The discovery suggests that a simple, well-timed control operation could help preserve quantum information longer without requiring new hardware, potentially improving the reliability of future quantum technologies.
