Quantum Entanglement: Scientists Extend Lifespan
15 Sep
Summary
- Scientists developed a 'flip operation' to control quantum entanglement.
- This technique can delay, prevent, or hasten entanglement sudden death.
- Precise timing of the operation is central to its effect on entanglement.
Scientists at the Raman Research Institute (RRI) in Bengaluru have developed a novel method to extend the lifespan of quantum entanglement, a critical component for quantum computing. Their research, in collaboration with international institutions, was published in Physical Review A and funded by the National Quantum Mission.
The team utilizes a 'flip operation' with precise timing to influence how quantum entanglement, the linked quantum properties of particles, interacts with the environment. This operation can delay, prevent, or even hasten entanglement sudden death, which is the disintegration of entanglement over time.
This advancement focuses on controlling the decay process, particularly for amplitude damping, a common source of noise in quantum systems. While not a complete solution to decoherence, the study suggests that precise timing of operations could become a vital part of the control toolbox for quantum systems, steering their evolution as they decohere.
