摘要

基于光子的量子技术依赖于非线性光学产生的相关对。因此,了解干扰的影响对这一创新领域的发展至关重要。在这里,我们重点介绍了量子光谱学作为最有前途的量子技术之一,在未来的应用中具有现实的前景。在这个领域中,频率噪声是最令人感兴趣的干扰。我们提出了一个实验,旨在测试和表征对不同水平的白色和彩色噪声的弹性,我们包括模拟来概括我们的发现。通过这项工作,我们证明了目标和噪声的光谱特性,以及量子相关性的强度,都起着至关重要的作用,并可能对性能产生巨大影响,特别是在可实现的光谱分辨率方面。值得注意的是,在特定区域中,该技术始终能够抵抗任何类型的噪声,这代表了一种优势,可以处理最佳测量并充分利用该技术的能力。

An experimental investigation of quantum frequency correlations resilience against white and colored noise
Quantum technologies based on photons rely on correlated pairs generated through nonlinear optics. Hence, understanding the impact of disturbances is of paramount importance for the development of this innovative field. Here we focus on the quantum spectroscopy as one of the most promising quantum technique showing a realistic perspective for a future employment. In this field, the most interesting disturbance is represented by the frequency noise. We present an experiment aimed at testing and characterizing the resilience against different levels of white and colored noise and we include simulations to generalize our findings. With this work we demonstrate that the spectroscopical properties of both the target and the noise, as well as the strength of the quantum correlations, play a crucial role and could have e huge impact on the performances, especially in terms of achievable spectral resolution. Remarkably, the presence of a specific region where the technology is always robust against any kind of noise represents an advantage allowing to deal with optimal measurements and fully exploit the capabilities of this technology.

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.
