使用线性光学的量子计算

Quantum Computing using Linear Optics

T. B. Pittman, B. C. Jacobs, J. D. Franson

摘要:

量子计算机有望解决传统计算机无法解决的数学问题。这些问题中的许多具有实际重要性,特别是在密码学和安全通信领域。APL正在开发一种量子计算的光学方法,其中比特或“量子比特”由单光子表示。我们的方法允许使用普通的(线性)光学元件,这些元件在大多数情况下都是现成的组件。最近的实验演示的各种逻辑门的单光子,一个原型存储器设备,和其他设备将被描述。

英文摘要:

Quantum computers are expected to be able to solve mathematical problems that cannot be solved using conventional computers. Many of these problems are of practical importance, especially in the areas of cryptography and secure communications. APL is developing an optical approach to quantum computing in which the bits, or "qubits", are represented by single photons. Our approach allows the use of ordinary (linear) optical elements that are available for the most part as off-the-shelf components. Recent experimental demonstrations of a variety of logic gates for single photons, a prototype memory device, and other devices will be described.
