量子计算中的多值逻辑门

Multi-valued Logic Gates for Quantum Computation

Ashok Muthukrishnan, C. R. Stroud,

摘要:

我们开发了一种用于多能级量子系统的量子计算的多值逻辑,并讨论了这种方法在按比例放大量子计算机方面的实际优势。推广二进制量子逻辑的方法,我们建立了任意数量的d-能级系统(d > 2)上的任意幺正操作可以分解成逻辑门,一次只对两个系统进行操作。我们表明,这样的多值逻辑门的线性离子阱计划的背景下,量子计算实验是可行的。通过在该方案中使用每个离子中的d个能级,我们将计算所需的离子数量减少了log d的因子。

英文摘要:

We develop a multi-valued logic for quantum computing for use in multi-level quantum systems, and discuss the practical advantages of this approach for scaling up a quantum computer. Generalizing the methods of binary quantum logic, we establish that arbitrary unitary operations on any number of d-level systems (d > 2) can be decomposed into logic gates that operate on only two systems at a time. We show that such multi-valued logic gates are experimentally feasible in the context of the linear ion trap scheme for quantum computing. By using d levels in each ion in this scheme, we reduce the number of ions needed for a computation by a factor of log d.
