Company profile
researched Aug 2026Lightsynq Technologies Inc. is a quantum technology company developing universal optical quantum interconnects intended to make quantum computers modular and enable scaling toward large-scale, fault-tolerant systems. Its stated architecture is designed to be broadly compatible with leading quantum computing modalities rather than tied to a single qubit platform.
The company's approach centers on integrated diamond photonic circuits. Its work spans quantum physics, quantum networking, quantum computing, quantum error correction, nanophotonics, systems engineering and research software development, which are also the areas in which it recruits.
Founding story
Lightsynq was co-founded by Mihir Bhaskar (Chief Executive Officer), Bart Machielse (Chief Technology Officer) and David Levonian (Chief Product Officer), who published a statement on the company's motivation titled "Why We Founded Lightsynq."
▸Full profile — market position, technology, go-to-market, geography
Market position
Lightsynq positions itself as a supplier of modality-agnostic quantum interconnects that bridge the gap between current quantum processors and large-scale quantum computers.
The company emphasizes an interconnect architecture that is not limited to one qubit modality, combined with in-house integrated diamond photonics and a team with backgrounds spanning quantum technologies research.
Technology
Lightsynq builds optical quantum interconnects that leverage integrated diamond photonic circuits. The interconnect architecture is described as universal and broadly compatible with leading quantum computing modalities, targeting the interconnection bottleneck that limits the scale of fault-tolerant quantum computers.
Go-to-market
The technology is aimed at builders and operators of quantum computing systems seeking to link modules together to reach larger, fault-tolerant machines.
Geography
The company is headquartered at 1284 Soldiers Field Rd, Brighton, Massachusetts 02135, USA.
