ITR: Center for Quantum Information Physics

这个NSF-ITR中等奖为耶鲁大学量子信息物理中心（CQuIP）提供支持。 CQuIP的研究人员正试图利用最近的工作，这些工作表明-通过用遵守量子力学定律的“量子位”取代正常位-理论上可以执行某些计算或程序，这是经典计算机不可能的。 潜在的应用包括没有加密密钥的安全通信;某些计算的指数加速，例如素数分解;等等。然而，这些优点只能通过比该领域的当前技术水平大得多的量子位互连系统来完全实现。 CQuIP的中心目标是展示与可扩展量子计算和量子通信的一系列不同和新颖的方法相关的原理证明。 在这个项目中研究的特定方法是基于超导微电路;半导体的自旋态;和超冷极性分子阵列。 CQuIP的研究也将大大推进我们对这些系统基础物理的理解。 正在研究的方法跨越了物理学的几个子领域，CQuIP的子组之间的互动鼓励跨越传统知识边界的思想交叉。 CQuIP的核心功能是量子信息科学新领域的博士后研究员，研究生和本科生的教育。 CQuIP还通过访客计划作为该领域研究人员的联系点;并通过在附近的小学院进行讲座计划作为教育推广中心。该NSF-ITR中等奖为耶鲁大学量子信息物理中心（CQuIP）提供支持。 CQuIP的研究人员将建立在最近的工作基础上，这些工作表明-通过将计算机中的正常位替换为遵守量子力学定律的位-理论上可以比任何正常计算机更快地执行某些计算（例如密码破译）。 然而，这样的量子计算将需要一个系统，其可用的量子比特远远多于表征该领域当前技术水平的少数“量子比特”。 CQuIP致力于开发这种大型“量子信息处理器”。 该中心将从实验和理论上研究几种不同的和有前途的量子比特技术：超导电路;半导体中的核自旋;以及激光捕获的极性分子阵列。 CQuIP的核心功能是量子信息科学新领域的博士后研究员，研究生和本科生的教育。 CQuIP还通过游客计划作为该领域研究人员的联系点;并作为教育推广中心，通过在附近的小学院进行讲座计划。

This NSF-ITR medium award provides support for the Center for Quantum Information Physics (CQuIP) at Yale University. Researchers in CQuIP are attempting to capitalize on recent work that has shown that--by replacing normal bits with "qubits" that obey the laws of quantum mechanics--it is in theory it is possible to perform certain calculations or procedures that are impossible with a classical computer. Potential applications include secure communication without cryptographic keys; exponential speedup of certain computations such as prime factorization; etc. However, these advantages can only be fully realized with interconnected systems of qubits that are much larger than the current state of the art for the field. The central aim of CQuIP is to demonstrate proof-of-principle relating to a diverse and novel set of approaches for scalable quantum computing and quantum communication. The particular approaches studied in this project are based on superconducting microcircuits; spin states of semiconductors; and ultracold polar molecule arrays. The research at CQuIP will also significantly advance our understanding of the basic physics underlying these systems. The approaches under study span several sub fields of physics, and interaction between the subgroups of CQuIP encourages cross-fertilization of ideas across traditional intellectual boundaries. A core function of the CQuIP is education of postdoctoral fellows, graduate students, and undergraduates in the new field of quantum information science. CQuIP also serves as a point of contact for researchers within the field, through a program for visitors; and as an educational outreach center, through a program of talks at nearby small colleges.This NSF-ITR medium award provides support for the Center for Quantum Information Physics (CQuIP) at Yale University. Researchers in CQuIP will build on recent work which has shown that--by replacing normal bits in a computer with bits that obey the laws of quantum mechanics--it is in theory possible to perform certain calculations (such as cryptographic code-breaking) qualitatively faster than on any normal computer. However, such quantum computation would require a system with substantially more usable quantum bits than the handful of "qubits" that characterize the current state of the art for the field. The CQuIP is devoted to development of such large-scale "quantum information processors". The center will investigate, experimentally and theoretically, several different and promising qubit technologies: Superconducting circuits; nuclear spins in semiconductors; and laser-trapped arrays of polar molecules.
