中国科研团队昨天在上海宣布,中国成功构建世界首台超越了电脑始祖ENIAC运行速度的“光量子计算机”,比之快了10倍。
综合中新社、中青在线等报道,中国科学技术大学院士潘建伟昨天介绍,其研究团队在2016年首次实现10光子纠缠操纵的基础上,构建出光量子(photon)计算原型机。
测试表明,该原型机的取样速度比国际同行此前进行类似实验的速度加快了2万4000倍。

此外,该团队通过和经典算法比较发现,这台光量子计算原型机比人类首台电子管计算机(ENIAC)和首台晶体管计算机(TRADIC)运行速度提高10至100倍。
潘建伟说,这台光量子计算机标志着中国在基于光子的量子计算机研究方面取得突破性进展,为最终实现超越经典计算能力的量子计算奠定了坚实基础。
量子计算机是指利用量子相干叠加原理,理论上具有超快的并行计算和模拟能力的计算机。曾有人比喻说,若现在传统计算机的速度是自行车,量子计算机的速度就好比飞机;例如,一台操纵50个微观粒子的量子计算机,对特定问题的处理能力可超过全球目前运算速度最快的超级电脑“神威太湖之光”。
据报道,作为量子计算的技术制高点,多粒子纠缠的操纵一直是国际角逐的焦点。在光子体系方面,潘建伟团队在国际上率先实现了五光子、六光子、八光子和10光子纠缠,一直保持着国际领先水平。
此外,国际学术界目前在基于光子、超冷原子和超导线路体系的量子计算技术发展展开竞争。由于量子计算的巨大潜在价值,欧美各国都在积极整合各方面研究力量和资源,开展协同攻关。同时,大型高科技公司如谷歌、微软、IBM等也强势介入量子计算研究。

光量子计算机能普及才牛逼,估计电价就涨,矿工成本增加,币价上升
