Abstract

We demonstrate the first free-space QKD experiment using an optical phased array chip for compact, fully integrated, and mobile free-space QKD systems. We achieve 1% QBER for a couple of beam steering conditions.

Free-space quantum information platform on a chip

Volkan Gurses, Samantha I. Davis, Neil E. Sinclair +2 more

Emerging technologies that employ quantum physics offer fundamental enhancements in information processing tasks, including sensing, communications, and computing. Here, we introduce the quantum phased array, which generalizes the operating principles of phased arrays and wavefront engineering to quantum fields, and report the first quantum phased array technology demonstration. An integrated photonic-electronic system is used to manipulate free-space quantum information to establish reconfigurable wireless quantum links in a standalone, compact form factor. Such a robust, scalable, and integrated quantum platform can enable broad deployment of quantum technologies with high connectivity, potentially expanding their use cases to real-world applications. We report the first, to our knowledge, free-space-to-chip interface for quantum links, enabled by 32 metamaterial antennas with more than 500,000 sub-wavelength engineered nanophotonic elements over a 550 x 550 $\mathrm{μm}^2$ physical aperture. We implement a 32-channel array of quantum coherent receivers with 30.3 dB shot noise clearance and 90.2 dB common-mode rejection ratio that downconverts the quantum optical information via homodyne detection and processes it coherently in the radio-frequency domain. With our platform, we demonstrate 32-pixel imaging of squeezed light for quantum sensing, reconfigurable free-space links for quantum communications, and proof-of-concept entanglement generation for measurement-based quantum computing. This approach offers targeted, real-time, dynamically-adjustable free-space capabilities to integrated quantum systems that can enable wireless quantum technologies.

An on-chip phased array for non-classical light

Volkan Gurses, Samantha I. Davis, Raju Valivarthi +3 more

Quantum science and technology can offer fundamental enhancements in sensing, communications and computing. The expansion from wired to wireless links is an exciting prospect for quantum technologies. For classical technologies, the advent of phased arrays enabled directional and adaptive wireless links by manipulating electromagnetic waves over free space. Here we demonstrate a phased array system on a chip that can receive, image and manipulate non-classical light over free space. We use an integrated photonic-electronic system with more than 1000 functional components on-chip to detect squeezed light. By integrating an array of 32 sub-wavelength engineered metamaterial antennas, we demonstrate a direct free-space-to-chip interface for reconfigurable quantum links. On the same chip, we implement a large-scale array of quantum-limited coherent receivers that can resolve non-classical signals simultaneously across 32 channels. With coherent readout and manipulation of these signals, we demonstrate 32-pixel imaging and spatially configurable reception of squeezed light over free space. Our work advances wireless quantum technologies that could enable practical applications in quantum communications and sensing.

High-dynamic free-space continuous-variable quantum access networks scheme via optical phased array

Bangde Zhu, Peng Huang, Kuntuo Zhu +2 more

Wireless quantum networking can provide flexible, rapidly deployable, and secure connectivity for mobile and infrastructure-limited scenarios. However, existing free-space continuous-variable quantum key distribution (CV-QKD) systems are still limited to point-to-point links, while dynamic multi-user access is hindered by bulky and slow mechanical beam steering. In this paper, we propose a free-space multi-user CV-QKD scheme based on an optical phased array. Based on a full-link model accounting for device imperfections and channel effects, numerical results demonstrate the feasibility of the proposed scheme under different atmospheric conditions and suggest its robustness and scalability. This work provides a promising route to rapidly reconfigurable free-space quantum access networks for highly dynamic near-range scenarios such as unmanned aerial vehicle swarms and emergency communications, and may inform future extensions toward satellite-based quantum networking.
