The project is relevant to the quantum technologies initiative, and University of Manchester support of Prof Winpenny's EPSRC Established Career Fellowship "From rings to nanostructures" (EP/R011079/1).The question will use electron paramagnetic resonance (EPR) spectroscopy to study molecular electron spin qubits. We will begin by studying compounds in solution phase, to measure coherence times. We will then move to molecules that contain two qubits. We will study these in dilute solution using double electron-electron resonance (DEER) methods. Once this is successfully completed we will carry out the same experiments but with our two qubit molecules included in a diamagnetic host lattice. This will allow us to carry out DEER on orientated single crystals and perform entanglement experiments.In the second half of the project more complicated molecules containing switches between two qubits will be studied, with the aim of perform universal quantum gates such as the CNOT gate.

该项目与量子技术倡议有关，曼彻斯特大学支持Winpenny教授的EPSRC建立的职业奖学金“从环到纳米结构”（EP/R011079/1）。该问题将使用电子顺磁共振（EPR）光谱来研究分子电子自旋量子比特。我们将从研究溶液中的化合物开始，来测量相干时间。然后我们将转向包含两个量子位的分子。我们将用双电子-电子共振（DEER）方法在稀溶液中研究这些。一旦成功完成，我们将进行相同的实验，但我们的两个量子比特分子包含在抗磁性主晶格中。这将使我们能够在定向单晶上进行DEER并进行纠缠实验。在项目的后半部分，将研究包含两个量子位之间开关的更复杂分子，目的是执行通用量子门，如CNOT门。
