最大规模量子材料模拟器制成

Core Insights - Australian silicon quantum computing company has developed the largest quantum material simulator to date, named "quantum twin," which consists of a 15,000 qubit array built with phosphorus atoms embedded in silicon chips, providing an unprecedented experimental platform for studying complex quantum materials [1] Group 1: Quantum Twin Capabilities - The "quantum twin" can reveal the working mechanisms of exotic and potentially useful quantum materials, aiding in the directed design and performance optimization of future materials [1] - This breakthrough is particularly significant for the study of superconductors, whose unique properties stem from quantum effects that traditional computers struggle to simulate accurately [1] Group 2: Technical Specifications - The team achieved precise control by positioning individual phosphorus atoms on a silicon substrate, with each atom acting as a controllable qubit, arranged in a regular two-dimensional grid to mimic the atomic structure of real materials [1] - The scale of 15,000 qubits far exceeds previous devices, which were based on thousands of ultra-cold atoms [1] Group 3: Applications and Future Potential - The platform has already simulated a classical theoretical model describing the phase transition of materials from conductors to insulators and measured the system's Hall coefficient changes with temperature, revealing its response characteristics under magnetic fields [2] - The "quantum twin" is expected to tackle controversial scientific challenges, such as the mechanisms of high-temperature superconductivity, which remain unclear despite traditional superconductors having well-defined principles [2] - Additionally, the "quantum twin" could support research in drug development and artificial photosynthesis [3]
