Which institute led the study on delaying entanglement sudden death?
- A.Indian Institute of Astrophysics
- B.Raman Research Institute
- C.Saha Institute of Nuclear Physics
- D.Tata Institute of Fundamental Research
Correct answer
Explanation
The correct answer is the Raman Research Institute, an autonomous institution of the Department of Science and Technology, whose Quantum Information and Computing laboratory led the work. The team worked with the University of Calgary and Louisiana State University, and the study was funded in part by the National Quantum Mission, the flagship mission of the same department. The other options name well known Indian research institutions in astrophysics, nuclear physics and fundamental research, none of which the release credits with this study. Two names are worth carrying away with the institute: Urbasi Sinha, the group leader of the laboratory and a senior professor there, who said that timing is not merely an experimental detail but a control resource, and Saumya Ranjan Behera, the lead author of the paper, which appeared in Physical Review A in July.

Practice Questions
What is meant by entanglement sudden death?
- A.The complete decay of both particles to the ground state
- B.The abrupt vanishing of entanglement at a finite time, before decay is complete
- C.The failure of a quantum computer to read out a result
- D.The collapse of a wave function on measurement
Show answer
The release explains that each of two entangled particles tends to slip from the excited state to the ground state the way an atom loses energy to its surroundings, and that the entanglement weakens as this happens.

- A.Dr. Parvinder Maini
- B.Prof. Ajay Kumar Sood
- C.Ateesh Kumar Singh
- D.Dr. Vishal Choudhary
Show answer
He described the integration as an institutional convergence that can lower R&D costs, avoid duplication of capital-intensive facilities and raise the use of publicly funded infrastructure.
