项目摘要

Quantum information processing (QIP) sounds like science fiction. In a conventional computer information is stored in a bit which can either be a 0 or a 1, and processing information involves changing 0 to 1 or 1 to 0. In a quantum computer information would be stored as a Qubit which is a super-position of 0 and 1. An analogy would be that a classical bit is like a light switch, which is either on or off, while a Qubit is a dimmer switch set simultaneously to all possible positions. Many systems have been studied as possible Qubits , but at present no efficient means for QIP exists. This is because the physical requirements are very precise and matching all requirements simultaneously is very difficult. In our previous work we have shown that molecular species can be made which have many of the correct characteristics. In this interdisciplinary project between a chemistry group at Manchester and a condensed matter physics group at Oxford we will fully characterise a range of such molecules and examine their suitability for QIP. By this route we intend to demonstrate, at least at prototype level, molecules and addressing techniques that will allow QIP. If QIP can be made to work it allows some calculations to be performed quickly which would be impossibly slow using conventional computers, and hence it would be massive technological step forward.

量子信息处理（QIP）听起来像科幻小说。在传统计算机中，信息存储在可以是 0 或 1 的位中，处理信息涉及将 0 变为 1 或 1 变为 0。在量子计算机中，信息将存储为量子位，它是叠加0 和 1。打个比方，经典位就像一个电灯开关，要么打开，要么关闭，而量子位则是一个同时设置在所有可能位置的调光开关。许多系统都被研究为可能的量子位，但目前尚不存在有效的 QIP 方法。这是因为物理要求非常精确，同时满足所有要求是非常困难的。在我们之前的工作中，我们已经证明可以制造出具有许多正确特征的分子物种。在曼彻斯特化学小组和牛津大学凝聚态物理小组之间的这个跨学科项目中，我们将全面描述一系列此类分子的特征，并检查它们对 QIP 的适用性。通过这种途径，我们打算至少在原型水平上展示允许 QIP 的分子和寻址技术。如果 QIP 能够发挥作用，它可以快速执行一些计算，而使用传统计算机则速度慢得不可思议，因此这将是技术上的巨大进步。
