用于灰度图像表示的量子线路的新设计

Novel Design of Quantum Circuits for Representation of Grayscale Images

Mayukh Sarkar

摘要:

量子计算的出现影响了世界各地的研究人员用有前途的技术来解决大量的计算问题。计算问题的解决方案的可行性,以及各种信息的表示,可能允许量子计算在不久的将来取代经典计算机。其中一个挑战是在量子计算机中表示数字图像。已经做了一些工作,使之成为可能。一种这样的有前途的技术,称为量子概率图像编码,需要最少数量的量子比特,其中n个像素的强度表示为log_2(n)量子比特的状态向量。虽然已有量子线路设计技术可以得到任意的态矢量,但它们考虑的是一般希尔伯特空间中的态矢量。但对于图像数据,仅考虑实向量空间就足够了,这可以将电路限制在较小的门集合中,并且可能可以减少所需的门的数量。在本文中,这种量子线路的建设已被提出。

英文摘要:

The advent of Quantum Computing has influenced researchers around the world to solve multitudes of computational problems with the promising technology. Feasibility of solutions for computational problems, and representation of various information, may allow quantum computing to replace classical computer in near future. One such challenge is the representation of digital images in quantum computer. Several works have been done to make it possible. One such promising technique, named Quantum Probability Image Encoding, requires minimal number of qubits, where the intensity of n pixels is represented as the statevector of log_2(n) qubits. Though there exist quantum circuit design techniques to obtain arbitrary statevector, they consider statevector in general Hilbert space. But for image data, considering only real vector space is sufficient, that may constraint the circuit in smaller gate set, and possibly can reduce number of gates required. In this paper, construction of such quantum circuits has been proposed.
