THE CHIP

Shoot a laser pulse at our SSPC quantum dot chip and it will deliver a stream of single photons. An optical cryostat equipped for confocal spectroscopy is required, but use is simple and straightforward. Don’t spend years developing this capability on your own. Use ours to further your research now.

Choose between standard single-photon chips or custom chips made to fit your research needs. Contact us for more information.

THE SPARROW SINGLE-PHOTON CHIP

single-photonThe new SPARROW single-photon source is is based on self-assembled InAs quantum dots coupled to a slow-light photonic-crystal waveguide made using a unique processing technology. The slow-light sections feature a low group velocity in order to increase light-matter interaction while the weak-dispersion sections enable more efficient chip out-coupling. Each end of the waveguide structure is coupled to carefully engineered suspended nano-beam waveguides and out-coupling gratings. The increased coupling efficiency from the quantum dot to the waveguide relies on the strong suppression of radiation modes together with an enhanced coupling into the waveguide mode. This makes it very robust to spatial and spectral dispersity meaning that the quantum dots are efficiently coupled.

HERE’S HOW IT WORKS

Shoot a laser pulse at our SQT quantum-dot chip and it will deliver a stream of single photons. An optical cryostat equipped for confocal spectroscopy is required, but use is simple and straightforward. Don’t spend years developing this capability on your own. Use ours to further your research now.

JOIN THE QUANTUM ALLIANCE

What will it actually take to get real bona-fide quantum-simulation and quantum-computing of the ground? Everyone agrees that it is a huge challenge –– but can it be solved? Why not work together to find out?

Our proposal is simple: We intend to build an alliance of top-tier researchers from the various areas of research that we know must contribute in order to make quantum computing happen.

We will work together to create a blueprint of how the key challenges in the field can be solved –– and to show how these advances can be brought together in what we hope will become the de-facto standard that enables any interested party to design, construct and market quantum computing devices.

WHY SHOULD YOU JOIN?

An operational blueprint for quantum computing will most likely be a cornucopia of patented knowledge. Your contributions may lead to significant license revenues from future users of the BLUEPRINT.

At this point in time massive investments are being made into the area. The EU recently announced the 2018 launch of a flagship-project that will dedicate 1 billion EUR to research into quantum technology. A consortium of leading researchers united to create a blueprint for quantum computing would have a good chance of receiving research grants from this funding source as well as from many others.

WHO WILL OWN THE BLUEPRINT?

We imagine leaving the actual blueprint in the public domain but having it consist of IP that is owned by the independent contributors to the project (eg. research groups and universities as well as private sector participants).

HOW WILL THE PROCESS BE STRUCTURED?

We are just getting started –– if you get aboard now you have a good chance of being part of this structuring process. During the next months we hope to imbue the project with a formal structure in terms of both organization, leadership, specific aims, participation selection process etc.

INTERESTED? YOU SHOULD BE!

Think about it for a second. Here is a chance to make a significant mark on the world by providing cutting-edge knowledge into what may become the blueprint for very significant future scientific and technological advances.
