通用量子处理器的可能实现

Probabilistic implementation of universal quantum processors

Mark Hillery, Vladimir Buzek, Mario Ziman

摘要:

我们提出了一个量子量子点的概率量子处理器。处理器本身由一个固定的门阵列表示。处理器的输入由两个寄存器组成。在程序寄存器中,指令集(程序)被编码。此程序应用于数据寄存器。处理器可以以一定的概率对维度N的单个量子点执行任何操作。如果运算是酉的,则概率一般是1/N^2,但对于更多限制的运算符集合,概率可能更高。事实上,在某些条件下,这个概率可以与量子点的希尔伯特空间的维数无关。

英文摘要:

We present a probabilistic quantum processor for qudits. The processor itself is represented by a fixed array of gates. The input of the processor consists of two registers. In the program register the set of instructions (program) is encoded. This program is applied to the data register. The processor can perform any operation on a single qudit of the dimension N with a certain probability. If the operation is unitary, the probability is in general 1/N^2, but for more restricted sets of operators the probability can be higher. In fact, this probability can be independent of the dimension of the qudit Hilbert space of the qudit under some conditions.
