Building and exploiting high quantum volume ion-trap processors

捕获离子设备已经在少量量子比特上展示了构建量子计算机所需的所有构建模块，其精度优于任何竞争技术。这个项目的目的是开发和利用一个世界级的中等规模的量子计算机，凭借高保真的任何量子比特到任何量子比特的纠缠门沿着低错误率，将在目前任何其他架构都无法实现的性能水平上运行。在学生期间，我们将开发和评估技术，以实现量子比特小寄存器的高保真控制，该项目将涉及实验和理论工作，包括：-建立一个使用新开发的捕获离子量子比特类型的设备-获得对单个原子离子的精确相干控制-开发和应用新的理论工具来理解和优化多量子比特耦合

Trapped-ion devices have demonstrated, on a small number of qubits, all the building-blocks required to build a quantum computer with precision better than any competing technology. The aim of this project is to develop and utilise a world-class intermediate-scale quantum computer that, by virtue of high-fidelity any-qubit-to-any-qubit entangling gates along with low error rates, will operate at a performance level currently unachievable in any other architecture.Over the course of the studentship, we will develop and evalualte techniquesto achieve high fidelity control of small registers of qubits, and approach the 50-qubit level while maintain entanglement fidelities beyond the state of the art.The project will involve both experimental and theoretical work, including:- building an apparatus that uses a newly developed type of trapped-ion qubit- obtaining precision coherent control over individual atomic ions- developing and applying new theoretical tools to understand and optimise many-qubit couplings
