The Chernick group specializes in synthetic organic chemistry of complex, highly functional conjugated systems for quantum information science (QIS) applications. A substantial amount of research in organic chemistry has focused on the tailored synthesis and characterization of molecules that undergo electron/energy processes for use in renewable energy applications, such as optoelectronic devices that rely upon charge transfer processes. This research has revealed key challenges that arise when the operating size of a device drops below the 10 nm size range. To reduce the size of the microchips that sustain the operation of a computing device, advancement to a single-molecule quantized regime is necessary. Hence, the research field of renewable energy devices has branched into the field of QIS, which is the study of quantum phenomena covering research disciplines pertaining to quantum teleportation, quantum entanglement, and quantum computation. The organic molecules the Chernick group synthesize are specifically designed to act as solar energy sensors to produce electronically excited states that can populate different spin states and/or undergo a charge transfer process. The generated charge transfer species contains an orbital lacking an electron (radical cation state) and an orbital with an additional electron (radical anion state) within the same molecule. These electrons can be spin-paired in either a singlet or triplet state. When these unpaired spin-states interact in an intramolecular manner with a covalently bound neighboring unpaired electron in the form of a stable free radical, multiple spin-states can be populated. This opens the door to the opportunity of creating single molecule organic quantum bits for QIS applications.

切尼克集团专门从事用于量子信息科学(QIS)应用的复杂、高功能共轭体系的合成有机化学。有机化学中的大量研究集中在经过电子/能量过程的分子的量身定做的合成和表征，用于可再生能源应用，例如依赖电荷转移过程的光电子器件。这项研究揭示了当设备的运行尺寸降至10纳米大小范围以下时出现的关键挑战。为了缩小维持计算设备运行的微芯片的尺寸，有必要发展到单分子量子化体系。因此，可再生能源器件的研究领域已经扩展到QIS领域，QIS是对量子现象的研究，涵盖了与量子隐形传态、量子纠缠和量子计算有关的研究学科。切尼克团队合成的有机分子被专门设计为充当太阳能传感器，以产生电子激发态，这些激发态可以填充不同的自旋态和/或经历电荷转移过程。生成的电荷转移物种在同一分子中包含一个缺少电子的轨道(自由基阳离子状态)和一个带有附加电子的轨道(自由基阴离子状态)。这些电子可以以单重态或三重态自旋配对。当这些未成对的自旋态以分子内的方式与以稳定自由基形式存在的相邻未成对电子共价束缚时，可以填充多个自旋态。这为创造用于QIS应用的单分子有机量子比特打开了大门。
