With this CAREER award, the Chemical Structure, Dynamic & Mechanism B Program of the Chemistry Division is supporting the research of Professor Danna Freedman at Northwestern University to develop and understand the smallest unit of a quantum computer, the qubit. Quantum computers can be vastly more efficient than current computers. Research on quantum computer is at the very early stages and focuses on creating the qubit. Toward this goal, Professor Freedman is using synthetic chemistry with the aim of addressing the fundamental questions surrounding the creation of a qubit at the molecular level. Professor Freedman will integrate research and education through three new initiatives. In the first initiative, the primary literature will be incorporated into the introductory chemistry curriculum through a combination of demonstrations, lecture examples and student created Wikipedia pages. In a separate initiative, Professor Freedman will continue her work with the Museum of Science and Industry to design and implement a new exhibit, which features her research on magnetic anisotropy. Finally, Professor Freedman will be creating opportunities for students to present their research, including organizing a colloquium for inorganic students in the Chicago area, a symposium at an American Chemical Society conference, and a symposium at an European Materials Research Society conference symposium. Any object that can be placed into a superposition of two states can be used as a qubit. Electronic spin is an appealing qubit candidate because the qubits can be manipulated by electron paramagnetic resonance spectroscopy, and their parameters can be tuned using chemical synthesis. Yet, the synthesis of viable candidate qubits has been stymied by rapid decoherence of electronic spin in molecules. As such, the synthesis and fundamental study of molecules with long-lived quantum coherences necessitates rational synthetic design principles to inform and enable the design of future long-lived qubits. Professor Freedman will continue to develop empirically derived design principles, employ these principles to synthesize candidate qubits, and scale new systems to develop multiple qubits in a single molecule. Her research program could provide important insights into decoherence.

有了这个职业奖，化学系的化学结构，动力学机制B计划支持西北大学的Danna Freedman教授的研究，以开发和理解量子计算机的最小单元，量子比特。 量子计算机可以比目前的计算机更有效。 量子计算机的研究还处于非常早期的阶段，重点是创建量子比特。 为了实现这一目标，弗里德曼教授正在使用合成化学，目的是解决围绕在分子水平上创建量子位的基本问题。 弗里德曼教授将通过三项新举措整合研究和教育。在第一项举措中，主要文献将通过演示，讲座实例和学生创建的维基百科页面的组合被纳入化学导论课程。 在另一项倡议中，弗里德曼教授将继续与科学与工业博物馆合作，设计和实施一个新的展览，其中包括她对磁各向异性的研究。最后，弗里德曼教授将为学生创造机会，介绍他们的研究，包括组织在芝加哥地区的无机学生座谈会，在美国化学学会会议的专题讨论会，并在欧洲材料研究学会会议专题讨论会的专题讨论会。任何可以被置于两个状态叠加的物体都可以被用作量子比特。电子自旋是一个有吸引力的量子比特候选者，因为量子比特可以通过电子顺磁共振光谱来操纵，并且它们的参数可以使用化学合成来调整。然而，可行的候选量子比特的合成一直受到分子中电子自旋的快速退相干的阻碍。因此，具有长寿命量子相干性的分子的合成和基础研究需要合理的合成设计原则来指导和实现未来长寿命量子位的设计。Freedman教授将继续开发经验衍生的设计原则，利用这些原则来合成候选量子位，并扩展新系统以在单个分子中开发多个量子位。 她的研究计划可以为退相干提供重要的见解。
