项目摘要
Quantum mechanics is the fundamental theory of nature. The quantum description of the physical world is often in marked contrast with our intuition. For instance, any attempt to observe a quantum object changes its state in a random and irreversible manner. In recent decades, advances in science and technology made it possible to isolate and manipulate simple quantum systems. Having a good handle on quantum systems gives new opportunities to understand the foundations of quantum mechanics. Moreover, recent research revealed that when information is encoded using quantum systems new opportunities for applications arise. Quantum computers outperform classical computers in many relevant tasks. In addition, quantum systems provide a way to transmit information in a secure manner. Both fundamental research and prospective applications using quantum systems focused traditionally on atoms and photons, which are weakly coupled to the surrounding world, making quantum effects prominent. However, in recent years genuine quantum effects were observed in solid-state systems, where the quantum behavior can be engineered. Superconducting quantum circuits, which are devices based on superconductors, are one of the most promising types of systems for research on foundations and applications of quantum mechanics.
Our research on superconducting quantum circuits addresses fundamental aspects of their physics and two types of practical applications. We will explore the physical origin of the magnetic flux fluctuations observed in superconducting devices. This type of fluctuation has many puzzling features and is detrimental to applications. Understanding the origin of flux noise is one of the most important problems in the field of condensed matter physics. We will use a set of tools recently developed in our group for systematic experimental investigations of flux noise. The first practical application we will explore is quantum computing using superconducting circuits. We will investigate both the implementation of logic gates and the protection against unavoidable errors in a quantum computer. The second application that we will pursue is the development of ultra-sensitive magnetic field sensors. We will further develop a new type of magnetometer invented by our group and we will apply it to measurements of small magnetic fields generated by the mechanical vibrations of nanometer size resonators and by small magnetic molecules.
This research will be carried out by undergraduate and graduate students, and by postdoctoral researchers. This proposal requires funding for the salaries of these researchers and for operation and equipment costs. Our research will have a major impact for fundamental research in quantum mechanics and quantum technologies. It will contribute to further establishing Canada as one of the leading countries in quantum information and technologies. Canada will also benefit through the training of the individuals working on this project, who will acquire skills transferable to many fields of research and industry.
量子力学是自然界的基本理论。对物理世界的量子描述经常与我们的直觉形成鲜明对比。例如,任何观察量子物体的尝试都会以随机且不可逆的方式改变其状态。近几十年来,科学技术的进步使孤立和操纵简单的量子系统成为可能。很好地掌握量子系统给我们提供了理解量子力学基础的新机会。此外,最近的研究表明,当使用量子系统对信息进行编码时,新的应用机会就会出现。量子计算机在许多相关任务上优于经典计算机。此外,量子系统提供了一种以安全方式传输信息的方式。无论是基础研究还是使用量子系统的潜在应用,传统上都集中在原子和光子上,它们与周围世界的耦合很弱,使得量子效应变得突出。然而,近年来在固态系统中观察到了真正的量子效应,在固态系统中,量子行为可以被工程化。超导量子电路是基于超导体的器件,是研究量子力学基础和应用的最有前途的系统之一。
我们对超导量子电路的研究涉及其物理的基本方面和两种类型的实际应用。我们将探索在超导装置中观察到的磁通波动的物理来源。这种波动有许多令人费解的特点,不利于应用。理解通量噪声的来源是凝聚态物理领域的重要问题之一。我们将使用我们团队最近开发的一套工具来系统地进行通量噪声的实验研究。我们将探索的第一个实际应用是使用超导电路的量子计算。我们将研究量子计算机中逻辑门的实现和对不可避免的错误的保护。我们将追求的第二个应用是开发超灵敏磁场传感器。我们将进一步开发我们团队发明的一种新型磁强计,并将其应用于测量纳米尺寸谐振器的机械振动产生的微小磁场和小磁性分子产生的磁场。
这项研究将由本科生和研究生以及博士后研究人员进行。这项提议需要为这些研究人员的工资以及操作和设备费用提供资金。我们的研究将对量子力学和量子技术的基础研究产生重大影响。它将有助于进一步确立加拿大作为量子信息和技术领先国家之一的地位。加拿大还将受益于对参与该项目的个人的培训,他们将获得可转移到许多研究和工业领域的技能。
