量子计算机的崩溃不一定会发生:核实验显示了一条出路

Meltdown in quantum computers needs not occur: Nuclear experiments show a way out

J. Flores, S. Yu. Kun, T. H. Seligman

摘要:

我们表明,相位记忆可以比能量弛豫系统的希尔伯特空间的指数大尺寸长得多,这一发现是由五十年的核实验记录,虽然信息是有点隐藏。对于量子计算机,维度为$2^{100}$或更大的希尔伯特空间将是典型的,因此这种效应可以显著地有助于减少量子计算机缩放到有用数量的量子比特的问题。

英文摘要:

We show that phase memory can be much longer than energy relaxation in systems with exponentially large dimensions of Hilbert space; this finding is documented by fifty years of nuclear experiments, though the information is somewhat hidden. For quantum computers Hilbert spaces of dimension $2^{100}$ or larger will be typical and therefore this effect may contribute significantly to reduce the problems of scaling of quantum computers to a useful number of qubits.
