Chronicle: Nurturing talents since 1990

In September 2026, scientists from India and the US demonstrated that precisely timed quantum operations can delay the loss of entanglement.

Key Points

• Research Institutions: The study involved Raman Research Institute, University of Calgary and Louisiana State University.
• Quantum Mission: The research was partly funded under the National Quantum Mission.
• Quantum Entanglement: It is a phenomenon where separated quantum systems remain correlated in their states.
• Entanglement Loss: Environmental interactions can weaken and eventually destroy quantum entanglement.
• Entanglement Sudden Death: Entanglement can disappear abruptly before individual quantum states completely decay.
• Optical Simulation: Researchers used light polarisation to simulate a two-level quantum system.
• Quantum Computing: Timed operations could potentially extend the lifetime of quantum information without hardware modifications.
• Noise Models: Researchers found that one experimental setup could represent two established models of environmental quantum noise.
