“九章三号”亮相了！

果然非同凡响！这台最新的光量子计算机算力比它的前辈“九章二号”提升了100万倍左右。

据来自中国科学技术大学的消息，该校中国科学院量子信息与量子科技创新研究院潘建伟、陆朝阳、刘乃乐等主导的量子计算机研究团队，与中国科学院上海微系统所、国家并行计算机工程技术研究中心深度合作，成功研发出了255个光子的量子计算原型机“九章三号”。

这台量子计算机以最优经典精确采样算法处理高斯玻色取样，其速度已比上一代的“九章二号”提升了100万倍。

那它的速度有多快呢？拿它与目前世界运算速度排名第一的计算机——美国能源部下属橡树岭国家实验室的“前沿”超级计算机去比较，按照官方的说法就是：“九章三号”在百万分之一秒时间内所处理的最高复杂度的样本，需要“前沿”超算（Frontier）运算二百亿年以上，算力堪称一骑绝尘。

这差的可不是一个级别，而是太多太多了，不过“前沿”超算的运算峰值速度已超过每秒100亿亿次，被认为是世界上第一台E级超算，已经是非常恐怖的运算能力了。

按一秒内的计算能力来看，九章三号在一秒钟内处理的最高复杂度的样本，“前沿”超算需要运算2亿亿年，而一年时间大约是3153.6万秒，那么换算下来九章三号处理最高复杂度样本的运算速度就是“前沿”超算的6307.2万亿亿倍。

不得不说这个差别实在是太大了，由此也可见量子计算机的巨大运算潜力。

量子计算机的运算速度为什么这么快呢？主要还在于它可以利用量子力学的叠加态和量子叠加的特性进行运算，它采用了量子比特代替传统计算机的二进制位，其运算不再是线性的，而是非线性的叠加式和纠缠式运算。

传统超算的运算模式如同用一根线去织布，量子计算的方式则如同用很多根经纬线去织布，那后者的速度当然要快多了！所以这种并行计算能力在一些特定算法上远超传统超算的速度。

正因为如此，当今世界各国都对量子计算的发展寄予厚望且努力发展，谁掌握了量子霸权（量子计算优越性），谁就能在算力上领先世界！

早在2021年时，中国科大团队就研制了113光子的可相位编程的“九章二号”和56比特的“祖冲之二号”量子计算原型机，一举使我国成为在光学和超导两种量子计算技术路线都达到了“量子计算优越性”的国家。

如今“九章三号”光量子计算机横空出世，算力再次领先世界，进一步巩固了我国在光量子计算领域的国际领先地位。
