摘要

在量子信息理论中,一个开放量子系统的演化——一个紧随其后的单一演化——是由量子通道或更一般地说,量子仪器来描述的。在这项工作中,我们将对撞机实验中的自旋和风味测量作为量子仪器。我们证明了完全决定输入-输出转换的Choi矩阵可以从给定模型中理论上计算,也可以从使用不同输入状态的一组最终状态测量(量子态断层扫描)中实验重建。Choi矩阵的实验重建,被称为量子过程断层扫描,为探测标准模型的潜在扩展提供了一种强大的新方法,可以预测不同的输入-输出转换。此外,该方法构成了量子力学本身的一个新的基础测试。作为一个例子,我们概述了应用于偏振轻子对撞机过程的量子过程层析成像方法。

Prospects for quantum process tomography at high energies
In quantum information theory, the evolution of an open quantum system—a unitary evolution followed by a measurement—is described by a quantum channel or, more generally, a quantum instrument. In this work, we formulate spin and flavour measurements in collider experiments as quantum instruments. We demonstrate that the Choi matrix, which completely determines input-output transitions, can be both theoretically computed from a given model and experimentally reconstructed from a set of final state measurements (quantum state tomography) using varied input states. The experimental reconstruction of the Choi matrix, known as quantum process tomography, offers a powerful new approach for probing potential extensions of the Standard Model, which predict different input-output transitions. In addition, the methodology constitutes a new foundational test of quantum mechanics itself. As an example, we outline the quantum process tomography approach applied to the process at a polarised lepton collider.

期刊介绍: Driven by advances in technology and experimental capability, the last decade has seen the emergence of quantum technology: a new praxis for controlling the quantum world. It is now possible to engineer complex, multi-component systems that merge the once distinct fields of quantum optics and condensed matter physics. Quantum Science and Technology is a new multidisciplinary, electronic-only journal, devoted to publishing research of the highest quality and impact covering theoretical and experimental advances in the fundamental science and application of all quantum-enabled technologies.
