Abstract

This talk will cover photonics integrated circuits (PICs) being developed at MIT Lincoln Laboratory for quantum applications, especially trapped-ion based quantum computers and optical clocks. We discuss optical signal routing, light collection for direct readout or remote entanglement generation, and laser and active component development.

Integrated technologies to enable compact trapped-ion quantum sensors

Robert McConnell

Trapped ions hold promise as the basis of highly accurate clocks and other quantum sensors. However, many real-world applications for quantum sensing require miniaturized, environmentally robust devices that can operate in the field. The significant experimental overhead imposed by free-space optics for control laser light delivery and collection has been an impediment to truly compact trapped-ion based clocks and sensors. The use of integrated technologies—including photonic waveguides, single-photon avalanche detectors (SPADs) and integrated electronics—provides a potential pathway towards overcoming these obstacles. I will discuss MIT Lincoln Laboratory’s recent efforts in this area, including demonstrations of integrated trapped-ion light delivery and collection and prospects for combining these technologies into a single chip-based trapped-ion reference.

Integrated photonics for scalable quantum systems: from UV nanophotonics to trapped-ion architectures

Rangana Banerjee Chaudhuri, Carl-Frederik Grimpe, Fatemeh Salahshoori +5 more

Photonic integrated circuits (PICs) offer compact and scalable solutions for trapped-ion quantum technologies. This work demonstrates photonic platforms that promise the potential integration of photonic components for light delivery and control across ultraviolet (UV) to near-infrared (NIR) wavelengths. Passive waveguides and beam-shaping structures provide precise and stable optical addressing of ions, while active elements such as modulators and switches enable dynamic, on-chip control for quantum operations. Materials like aluminum oxide (Al2O3) and aluminum nitride (AlN) are evaluated to illustrate how functionality can be tailored to spectral needs. These integrated photonic systems reduce reliance on bulky free-space optics, improve alignment stability, and support future development of compact quantum sensors, atomic clocks, and scalable quantum processors.
