Abstract

We demonstrate a quantum analog of electromagnetic phased arrays with more than 1,000 functional components integrated on a silicon photonic chip. With an array of 32 metamaterial antennas and 32 quantum-limited coherent receivers employing homodyne detection, we perform imaging, beamforming and beamsteering with squeezed light over free space.

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.

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.

Strategies and components for quantum limited precision measurement in integrated quantum photonics

Jonathan Frazer, Joel F. Tasker, Jake Biele +11 more

Integrated photonics is providing a compelling route for quantum limited and quantum enhanced technologies, including computing communications and optical sensing. This is because chip-scale integrated photonics can offer miniaturization as well as possible scalability in manufacture. Here we will discuss recent results in developing integrated homodyne detection integrated in silicon photonics. We discuss its combination with integrated electronics to demonstrate high bandwidth performance and its use to measure squeezed light over a broad bandwidth, out to 9GHz. This demonstrates a performance enhancement that is relevant to quantum technology and is due to miniaturization. We will discuss possible applications of of integrated quantum noise listed homodyne detection, including a strategy to perform quantum limited absorption estimation using integrated photonics and coherent states.

9 GHz measurement of squeezed light by interfacing silicon photonics and integrated electronics/Main text

Joel F. Tasker, Jonathan Frazer, Giacomo Ferranti +1 more

Photonic quantum technology can be enhanced by monolithic fabrication of both the underpinning quantum hardware and the corresponding electronics for classical readout and control. Together, this enables miniaturisation and mass-manufacture of small quantum devices---such as quantum communication nodes, quantum sensors and sources of randomness---and promises the precision and scale of fabrication required to assemble useful quantum computers. Here we combine CMOS compatible silicon and germanium-on-silicon nano-photonics with silicon-germanium integrated amplification electronics to improve performance of on-chip homodyne detection of quantum light. We observe a 3 dB bandwidth of 1.7 GHz, shot-noise limited performance beyond 9 GHz and minaturise the required footprint to 0.84 mm. We use the device to observe quantum squeezed light, from 100 MHz to 9 GHz, generated in a lithium niobate waveguide. This demonstrates that an all-integrated approach yields faster homodyne detectors for quantum technology than has been achieved to-date and opens the way to full-stack integration of photonic quantum devices.
