Developing Quantum Information Processors

量子力学对信息处理提出了基本的物理限制。通过构建量子计算机、量子通信系统、量子传感器和执行器，我们有效地达到了物理定律所允许的功率和精度极限。量子信息处理（QIP）有望触及我们生活的几乎每个方面：我们与环境和彼此互动的方式，以及我们存储和处理知识的方式。实现这一转变所必需的量子设备的开发才刚刚开始。今天，我们有QIP的小型试验台。其中最通用的仍然是基于自旋的处理器。我们建议将这些固态的、基于自旋的量子处理器进一步发展成量子传感器和执行器。这些将是导航和控制微观量子世界的工具。

Quantum mechanics poses the fundamental physical limits to information processing. By building quantum computers, quantum communication systems, and quantum sensors and actuators, we effectively reach the limits in power and accuracy allowed by the laws of physics. Quantum information processing (QIP) promises to touch nearly every aspect of our lives: the way we interact with the environment and each other and the way we store and process knowledge. The development of quantum devices necessary to achieve this transformation is just beginning. Today we have small test-beds for QIP. The most versatile of these remains the spin-based processors. We propose to further develop these solid-state, spin-based quantum processors into quantum sensors and actuators. These will be the tools for navigating and controlling the microscopic quantum world.
