Chinese scientists have established a quantum computer prototype named "Jiuzhang 2.0" with 113 detected photons, achieving major breakthroughs in quantum computational speedup.
In the study, Gaussian boson sampling (GBS), a classical simulation algorithm, was used to provide a highly efficient way of demonstrating quantum computational speedup in solving some well-defined tasks.
With 113 detected photons, "Jiuzhang 2.0" can implement large-scale GBS septillion times faster than the world's fastest existing supercomputer.
The study, led by the renowned Chinese quantum physicist Pan Jianwei, was published online in the journal Physical Review Letters on Monday Beijing Time.
