Fibonacci任意子拓扑量子计算的单比特编织门编译

Compiling single-qubit braiding gate for Fibonacci anyons topological quantum computation

Mohamed Taha Rouabah

摘要:

拓扑量子计算是量子计算机的一种实现方式,它从根本上减少了退相干。拓扑量子比特被编码在二维准粒子任意子的拓扑演化中,通过将这些任意子编织成一个拓扑保护的电路模型,可以构造出一组通用的量子门。在本研究中,我们回顾了这种新兴的量子计算方案的基础知识,并说明了如何采用由三个Fibonacci任意子构建的拓扑量子比特,通过交换组成它的任意子来实现无泄漏的编织门。使用蛮力搜索方法,数值实现了一个近似Hadamard量子门的单量子比特编织门。用于这一目的的算法进行了解释和数值程序公开共享的复制和进一步使用。

英文摘要:

Topological quantum computation is an implementation of a quantum computer in a way that radically reduces decoherence. Topological qubits are encoded in the topological evolution of two-dimensional quasi-particles called anyons and universal set of quantum gates can be constructed by braiding these anyons yielding to a topologically protected circuit model. In the present study we remind the basics of this emerging quantum computation scheme and illustrate how a topological qubit built with three Fibonacci anyons might be adopted to achieve leakage free braiding gate by exchanging the anyons composing it. A single-qubit braiding gate that approximates the Hadamard quantum gate to a certain accuracy is numerically implemented using a brute force search method. The algorithms utilized for that purpose are explained and the numerical programs are publicly shared for reproduction and further use.
