Using light for controlling and manipulating isolated microscopic systems is at the foundation of quantum computation and quantum information processing.
Currently, most of the existing experimental setups rely on conventional free-space optics, that are bulky and hardly scalable. However, recent results suggest that photonic integrated circuits and nanophotonics could allow us to overcome some of the main challenges in these fields, in particular considering the future scaling of quantum systems, which is not only a critical requirement for scientific progress but also for the future commercialization of quantum technologies based on trapped particles.
This series of seminars, jointly organized by the Optica Technical Groups of Integrated Photonics and Optical Cooling and Trapping, will feature three distinguished speakers who will share insights on their progress of using integrated nanophotonic circuits for the trapping and manipulation of neutral atoms, ions and nanoparticles. Details on each of the three talks are below. Attendees only need to register once and will be able to attend any of the three talks.

Silicon Photonics for LiDAR Sensors, Augmented-Reality Displays, Biophotonic Tweezers, Trapped-Ion Quantum, and BeyondDate: 10 April 2025 In this session, Jelena Notaros (Massachusetts Institute of Technology) will give a talk on developing novel OPA-based platforms, devices, and systems that enable innovative chip-based solutions to high-impact problems. Abstract: By enabling the integration of millions of micro-scale optical components on compact millimeter-scale computer chips, silicon photonics is positioned to enable next-generation optical technologies that facilitate revolutionary advances for numerous fields spanning science and engineering. An emerging class of silicon-photonics systems is integrated optical phased arrays (OPAs), which enable manipulation and dynamic control of free-space light in a compact form factor, at low costs, and in a non-mechanical way. This talk will highlight our work on developing novel OPA-based platforms, devices, and systems that enable innovative chip-based solutions to high-impact problems in areas including LiDAR sensing for autonomous vehicles, augmented-reality displays, free-space optical communications, optical trapping for biophotonics, 3D printing, and trapped-ion quantum engineering. |
Nanophotonic Interconnects for Atom Array Quantum NetworksDate: 24 April 2025 In the second session of this series, Hannes Bernien (University of Innsbruck, IQOQI, University of Chicago) will give a talk discussing how atomic qubits arrays can be coupled to arrays of nanophotonic crystal cavities. Abstract: Neutral atom arrays are one of the most promising quantum processor architectures. However, for practical quantum computing a million physical qubits or more will be needed. Reaching such numbers will very likely need a distributed architecture in which modules with 10s of thousand qubits are linked to each other using photons. Nanophotonics can provide an efficient optical interface to enable such links. Here I will show how atomic qubits arrays can be coupled to arrays of nanophotonic crystal cavities and present our progress towards distributing entanglement between multiple nodes of a quantum network. |
Integrated Photonics for Scalable Ion TrapsDate: 08 May 2025 In the final session, Jonathan Home (ETH Zürich) will give a talk on using integrated optics to perform entangling gates and deliver light to multiple zones of an ion trap chip. Abstract: Trapped ions are among the most promising paths to realizing quantum computers, having exhibited the highest fidelities and long coherence times. Scaling up will require the adoption of new technologies, and can be facilitated by new approaches. In particular, the use of integrated optics allows to deliver light in a multiplexed manner to arrays of ions in micro trap arrays. I will describe how we have used integrated optics perform entangling gates and deliver light to multiple zones of an ion trap chip in scalable manner, and give an impression of the new types of control are enabled by this approach. This work has now been extended to waveguide delivery at wavelengths from 375 to 866 nm, using alumina and silicon nitride waveguides. I will also give an outlook to the challenges ahead in the use of integrated waveguide technologies for scaling up trapped ion quantum computers. |
