Breakthrough in Quantum Computing: Using AI to Build Defect-Free Qubit Arrays
UPSC Relevance
Prelims: Science & Technology (Quantum Technology, Quantum Computing, Artificial Intelligence - AI, Neural Networks, Lasers).
Mains: GS Paper 3 (Science and Technology- developments and their applications and effects in everyday life; Awareness in the fields of IT, Space, Computers, robotics, nano-technology, bio-technology).
Key Highlights from the News
Major Breakthrough: A crucial breakthrough in building quantum computers. Researchers in China developed a new technology to quickly construct large, defect-free arrays of qubits.
Challenge Solved: The main obstacle to building quantum computers was the delay in precisely arranging thousands of qubits in their correct positions without errors.
New Technology: To overcome this challenge, researchers used a new method combining Artificial Intelligence (AI) and laser holograms.
Role of AI: The AI model rapidly calculates how to move thousands of atoms (used here as qubits) to their precise positions simultaneously.
Result: Using this technology, a defect-free array of 2,024 atoms could be built in just 60 milliseconds. This is much faster and more scalable than previous methods.
Qubits Used: In this experiment, neutral atoms (e.g., rubidium atoms) held by optical tweezers were used as qubits.
