Simulating High Energy Physics with Quantum Photonics

该项目旨在使用光子量子模拟器来研究粒子物理学中的关键开放问题，分别涉及中微子和介子。该项目将解决中微子的“无菌”味道的存在，中微子相互作用如何改变味道振荡，以及中性B介子振荡(它们与其反粒子之间)违反CP对称性的程度超过标准模型所允许的程度。光子学是一个通用的平台，用于模拟费米子和任意子统计以及非厄米哈密顿。量子光子学实验已经发展到可以产生、相干操纵和探测&gt；100光子的地步。利用电信和微电子行业成熟的制造能力，可以将约1000个光学部件共同集成到一个光子量子处理器中。在这个项目中，我们的目标是利用光子学提供的可重构能力，将粒子物理中研究的复杂系统映射到可控的、众所周知的量子光子学平台。这类模拟量子模拟器在两个系统的动力学之间存在一对一的映射，已被证明是在没有容错量子计算机的情况下进行有用但特定的量子计算的一条很有前途的途径。布里斯托尔大学拥有一个受人尊敬的粒子物理学小组，与LHCb和CERN有着长期的联系；该大学还拥有广泛的、世界领先的光子量子技术专业知识和基础设施。该项目旨在促进跨学科研究，为高能界和粒子物理界带来量子计算和模拟的好处。我们的雄心是通过对英国量子计算和模拟技术进行建模，让英国粒子物理研究人员发现新的基础物理。

This project aims to use photonic quantum simulators to investigate key open questions in particle physics involving, separately, neutrinos and mesons. The project will tackle the existence of 'sterile' flavours of neutrino, how flavour oscillations are modified by neutrino interactions, and neutral B-meson oscillations (between themselves and their antiparticle) that violate CP symmetry by a greater degree than allowed by the Standard Model. Photonics is a versatile platform for simulating fermionic and anyonic statistics, and non-Hermitian Hamiltonians. Quantum photonics experiments have progressed to the point where >100 photons can be generated, coherently manipulated, and detected. Leveraging the mature fabrication capabilities of the telecoms and microelectronics industries has allowed ~1000 optical components to be co-integrated into a single photonic quantum processor. In this project we aim to use the reconfigurability afforded by photonics to map complex systems studied in particle physics into the controllable and well understood platform of quantum photonics. Such analogue quantum simulators, where there is a one-to-one mapping between the dynamics of both systems, have been shown to be a promising avenue to useful but specific quantum computation without a fault tolerant quantum computer.Bristol University hosts an esteemed group in particle physics with longstanding links to the LHCb and CERN; the university also hosts extensive and world leading expertise and infrastructure in photonic quantum technologies. This project aims to foster interdisciplinary research, bringing the benefits of quantum computing and simulation to the high energy and particle physics community. Our ambition is for new fundamental physics to be discovered by UK particle physics researchers through modelling carried out on UK quantum computing and simulation technologies.
