πŸ”† Quantum Entanglement

πŸ“ Why in News?
🟒 Scientists from RRI, University of Calgary and Louisiana State University (LSU) demonstrated a method to delay or avoid sudden quantum entanglement loss using a single flip operation.

πŸ“ What is Quantum Entanglement?
🟒 A phenomenon where the quantum states of two or more particles become correlated.
🟒 Measurement of one particle’s state is directly related to the state of another, regardless of spatial separation.
🟒 It is a fundamental resource for quantum computing, quantum communication, quantum information processing and quantum cryptography.

πŸ“ Loss of Entanglement
🟒 Quantum systems are highly sensitive to external interactions and environmental noise.
🟒 Loss of quantum information due to such interactions is called decoherence.
🟒 As particles transition from an excited state to a ground state, their degree of entanglement may diminish.

πŸ“ Entanglement Sudden Death
🟒 Entanglement can vanish completely within a finite time, even though the underlying particle-decay process is still incomplete.
🟒 This phenomenon is known as entanglement sudden death.

πŸ“ New Study
🟒 Researchers applied a single flip operation at a strategically chosen point during the decay process.
🟒 The effect depends on the timing of the flip operation:
β†’ 🟒 Delay the onset of sudden death
β†’ 🟒 Prevent sudden death entirely
β†’ 🟒 In some cases, accelerate sudden death

πŸ“ Significance
🟒 Can help extend the lifetime of quantum entanglement.
🟒 Precisely timed operations can control entanglement dynamics without necessarily modifying existing quantum hardware.
🟒 May help preserve quantum information for longer durations.
🟒 Such control strategies can complement hardware-based approaches to manage quantum errors and decoherence.

πŸ“Œ UPSC Mains Model Question

What is quantum entanglement? Explain the phenomenon of β€˜entanglement sudden death’ and discuss how its controlled manipulation can contribute to the development of quantum technologies.
