• Sparrow Quantum is positioning itself to develop into a market chief in quantum light-matter interfaces for business quantum applied sciences.
• Sparrow Quantum’s expertise is undepinned by 20 years of pioneering analysis tasks carried out along with his quantum photonics analysis group on the famend Niels Bohr Institute (NBI).
• Important Quote: “Sparrow Quantum’s expertise is rooted in additional than twenty years of analysis, which has given us a deep understanding of the system’s physics. This understanding has translated into the event of gadgets with distinctive specs when it comes to the standard of the emitted gentle particles. Our firm is widely known as a frontrunner in single-photon sources, and now we have demonstrated the world’s highest light-matter coupling effectivity.” — Kurt Stokbro, CEO of Sparrow Quantum

Whereas it might look like a latest improvement, Sparrow Quantum is definitely the end result of many years of in depth basic analysis into quantum dot sources with a solid-state single photon supply and light-matter interfaces, in response to the corporate’s founders.

Professor Peter Lodahl, who now serves as Sparrow Quantum’s chief science officer, initiated the analysis into what would develop into Sparrow Quantum’s expertise greater than 20 years in the past via a sequence of pioneering analysis tasks carried out along with his quantum photonics analysis group on the famend Niels Bohr Institute (NBI) in Copenhagen, Denmark.

Lodahl, who at present heads the Hybrid Quantum Networks Hy-Q Heart of Excellence, was at the moment finding out the management of sunshine emission utilizing intricate photonic nanostructures. What began out as basic analysis started to disclose business prospects, notably because the quantum applied sciences market started to mature.

“Finally, we began to see that now we have an especially promising constructing block, which is that this deterministic supply of single photons,” mentioned Lodahl. “In different phrases, this can be a supply the place you push a button, and out comes a photon. The qubit high quality, i.e., the constancy of the photons we generate, may be very excessive. This end result comes from a deep bodily understanding of the system and implementing it within the lab. We’re seeing increasingly more that this deterministic light-matter interface can now function the inspiration of a spread of functions.”

The purpose of the corporate, which was formally based by Lodahl in 2015, is so simple as it’s formidable: To develop into the market chief in quantum light-matter interfaces for business quantum applied sciences.

The Sparrow Quantum group is making progress on that purpose by placing a product in the marketplace for researchers proper now and interesting with firms that may make up their rising buyer base, akin to distributors and suppliers of photonic quantum computing programs, in addition to quantum communication and quantum web firms.

Proper now, the corporate’s flagship product is an on-chip single-photon supply that gives lengthy strings of greater than 100 single photons with none loss in high quality. The system can emit greater than 20 million single photons per second into an optical fiber, which will be deployed by prospects straight for functions akin to photonic quantum computing, quantum simulations, or quantum communications experiments.

“As a element provider, our light-matter interfaces are integral to the business quantum stack,” mentioned Lodahl. “Whereas our final purpose is to supply elements for business quantum computing and communications programs, we at present serve the analysis group as our preliminary buyer base.”

Sparrow Benefits
In accordance with Lodahl, Sparrow Quantum gear gives distinct benefits for its shoppers.
Maybe a very powerful benefit is the many years of basic analysis and years of expertise making use of the expertise for business use. This expertise gives a strong basis of information, experience, and finest practices that may be leveraged to optimize and enhance the expertise for real-world functions.

The experience that has been gained working with {hardware} and quantum supplies improvement will be leveraged for optimizing the system’s efficiency and scalability for functions akin to quantum repeaters, quantum web, and quantum computing, in response to Kurt Stokbro, CEO of Sparrow Quantum.

“Sparrow Quantum’s expertise is rooted in additional than twenty years of analysis, which has given us a deep understanding of the system’s physics,” mentioned Stokbro. “This understanding has translated into the event of gadgets with distinctive specs when it comes to the standard of the emitted gentle particles. Our firm is widely known as a frontrunner in single-photon sources, and now we have demonstrated the world’s highest light-matter coupling effectivity.”

The corporate additionally has created a deep understanding of growing architectures, offering a dependable and environment friendly platform for implementing quantum applied sciences.

“We have now at all times been very severe concerning the architectures,” mentioned Lodahl. “We’re very severe about discovering out how the expertise scales up – how will we assemble quantum repeaters based mostly on deterministic photon-emitter interfaces? How a few full-fletched quantum web? Or a fault-tolerant photonic quantum pc? – that basically requires a whole lot of theoretical understanding of the {hardware} additionally to be able to perceive tips on how to scale up the expertise in probably the most resource-efficient method.”

The construction of Sparrow Quantum’s expertise, itself, is one other benefit, in response to Stokbro.

“One necessary element of our expertise is that it’s planar, in comparison with different single photon sources which might be emitting vertically,” mentioned Stokbro. “The planar construction provides you some additional prospects to combine different options onto the chip. As an example, you are able to do filtering on the chip degree, in addition to combine extra elements.”

Sparrow Quantum has different geographic benefits.

“In Denmark, we’re very, very sturdy in interfacing principle with the {hardware} improvement,” mentioned Lodahl. “Additionally, quantum supplies improvement is in a powerful place on this ecosystem, and we are able to use this experience in a strong method,” mentioned Lodahl.

Denmark can also be house to a burgeoning quantum ecosystem, which might assist Sparrow Quantum’s progress. Taking this a step additional, Sparrow Quantum advantages from Denmark’s place as a crossroads of pharmaceutical and life sciences analysis, that are fields that many consultants anticipate will probably be enhanced by quantum computing.

Sparrow Quantum’s Imaginative and prescient
Based mostly on these benefits, firm officers are satisfied of their imaginative and prescient of turning into the market chief in light-matter interfaces. In addition they see a path ahead to realize that purpose.

Stokbro sees the preliminary low-hanging fruit is to supply a high-quality single-photon supply for the analysis group and in addition for quantum simulation of quantum computing programs – and past.

“In the long term, although, there will probably be a necessity for light-matter interfaces for the quantum web, to attach quantum computer systems collectively.”

Sparrow Quantum’s fast steps to appreciate that imaginative and prescient is to search out the best folks with complementary experience so they’re aggressive on this extremely technical subject. In addition they imagine in creating actual, sustainable worth of their merchandise in order that their prospects and shoppers can obtain their very own objectives.

Sparrow Quantum not too long ago introduced a 31 million DKK — about $4.9 million US —  seed founding round.
