一款革命性低能耗放大器问世 仅在读取量子比特时才“激活”

Core Insights - A revolutionary amplifier developed by scientists at Chalmers University of Technology in Sweden consumes only one-tenth of the power of existing top amplifiers and operates in a pulse mode, activating only when reading quantum bit information, significantly reducing decoherence effects in quantum systems [1][2] Group 1: Amplifier Technology - The new amplifier features an "on-demand operation" capability, activating only when quantum bit signals are read, similar to a voice-activated light [2] - The response time of the amplifier has been optimized to 35 nanoseconds, aligning perfectly with the rapid reading requirements of quantum pulses [2] - This device maintains high performance while consuming low power, addressing energy consumption and interference issues during quantum bit reading [2] Group 2: Quantum Computing Implications - The amplifier's ability to reduce background noise and thermal interference is crucial for extending the coherence time of quantum states, enhancing the stability and reducing error rates in quantum computing [2] - As the number of quantum bits increases, achieving precise and independent measurements will become a core challenge, and this amplifier provides a viable technical pathway to address this issue [2]
