Quantum Control of Multiphoton Dynamics using Light-Matter Interactions in Nanoscale Systems
Abstract
One of the main goals of quantum physics is to exploit nonclassical effects in nanoscale systems to implement operations that cannot be performed on classical devices. This possibility depends on the preparation of robust and controllable quantum systems comprising multiple interacting particles. These complex quantum systems can host many forms of interference and scattering processes that are essential to perform operations that are intractable on classical systems. Recent efforts devoted to the preparation of quantum multiparticle systems have relied on platforms as diverse as trapped atoms, quantum dots, nitrogen-vacancy centers in diamond, and photonic quantum systems. However, despite existing limitations in the control of photonic states, these constitute one of the most promising platforms for the development of controllable quantum multiparticle systems. Here, it is proposed a novel research program that aims to demonstrate robust control of the quantum coherence properties of multiphoton systems and their evolution using light-matter interactions in metallic nanostructures. This platform will make use of optical near fields to control scattering among photons and plasmons. The possibility of engineering quantum coherence and the quantum statistics of multiparticle systems will enable robust control of quantum systems at a new fundamental level in which their excitation mode is manipulated. Hitherto, light-matter interactions mediated by plasmonic near fields have not yet been used in traditional quantum optical setups to control the nonclassical statistical properties of multiparticle systems. The proposed research program will lead to the first formulation of the quantum Van Cittert-Zernike theorem for nonclassical multiphoton systems. This theorem will provide a theoretical framework that will enable the use of plasmonic near fields for the preparation of complex entangled multiphoton systems. This platform will rely on high-transmission nanoscale systems that support plasmonic near fields to provide efficient control of the quantum properties of physical systems. In the realm of quantum optics, the underlying statistical fluctuations of photons define different kinds of light. Consequently, the proposed research program has the potential to be transformative, taking the dynamics of plasmonic near fields from its fundamental physics to the development of nanoscale systems for robust quantum control. The possibility of using light-matter interactions to control the quantum fluctuations that define the nature of multiparticle systems have important implications for the Department of Defense (DoD). Over the past decade, DoD has made investments in the field of quantum optics aiming to achieve robust coherent state transfer, and creation and manipulation of entanglement. Unfortunately, the robust control of multiphoton entanglement remains elusive. However, the interest in this research resides in its potential for enabling robust technologies for quantum sensing and metrology. Indeed, the goals of this proposal have important consequences for these quantum technologies. The development of nanoscale platforms to exert control of the quantum fluctuations of multiphoton systems have dramatic implications for the sensitivity of quantum sensing protocols. The versatility of the proposed platform shows potential to enhance the sensitivity associated to the estimation of small physical parameters. Furthermore, it is worth noticing that the completion of this research will enable nanoscale platforms for general, unconditional, and scalable control of multiphoton entanglement. Remarkably, the possibility of demonstrating such degree of control of quantum multiphoton systems has constituted one of the main goals of DoD for the past ten years.
