Qunnect

Researchers have successfully demonstrated entanglement between telecom-wavelength photons and room-temperature quantum memory, a significant advancement towards practical quantum networks. This new system operates without cryogenic cooling, making it compatible with existing fiber-optic infrastructure while achieving up to 90.2% entanglement fidelity. With a capacity to generate 1,200 entangled photon-memory pairs per second, it offers a steady stream of reliable quantum links essential for scalable quantum communication. While challenges such as atomic diffusion currently limit storage times, proposed improvements could enhance long-distance entanglement distribution. This work lays the foundation for future quantum repeaters that could be integral to global quantum networking efforts. https://hubs.la/Q03cw_8-0 #QuantumNetworking #Photonics #QuantumMemory

We love being part of the Brooklyn Navy Yard Development Corporation Family. There is a wall here in our building with the photos of some of the hardworking creators on the campus. As it happens, two of the co-authors of our most recent #quantum memory entanglement paper (https://lnkd.in/eJzneU9A) are on that wall too! And you can see Yang Wang while optimizing the quantum memory to improve its coherence time! A big shoutout to Jaeda Mendoza who joined us right after her undergrad because of how much she loved to work on quantum technologies. And now for her first paper she demonstrated the first ever quantum entanglement between a telecom photon and a room temperature quantum memory! Way to go Jaeda!

Today we announced the ability to entangle telecom photons, generated by our entanglement source product, with a 2nd generation version of the company’s room temperature quantum memory product.? This capability is the core of quantum protocols to unlock future applications such as interfacing quantum computers within data centers and establishing quantum repeaters for long distance secure communication. In the past 5 years Qunnect has been the first, globally, to commercialize a suite of quantum networking products leveraging atomic vapor to generate, store and distribute entanglement over telecom fiber. Quantum memories provide the critical function of timing control within a network or data center. Qunnect’s QU-MEM, launched in 2021, and the 2nd generation used for this work, operate at room temperature, without the requirement for extreme cooling or vacuum, necessitated by all cold atom and solid state memory technologies. Not only does this design consider the importance of energy consumption for future data centers, but cooled technologies necessitate time to prep the system, reducing the true on-demand nature and network uptime. Qunnect’s entanglement source (QU-SRC) is the only commercial product generating high rate, bichromatic, polarization-entangled pairs from atomic vapor. As atoms are identical, they produce highly indistinguishable photons, further increasing the success rate of the transactions. An often overlooked scaling challenge is the compounded loss suffered from inefficient interfacing of entanglement sources with both the network and the quantum memories.? Qunnect’s QU-SRC is the only commercial product with <1GHz linewidth photons produced at precision frequencies for native compatibility with atomic memories, sensors and computers.? Furthermore, QU-SRC is the only source on the market where one half of the entangled pair is produced at a telecom frequency for ready transmission, eliminating losses incurred by frequency conversion. The article below by our CSO breakdowns this achievement by our team. A major congrats to the team, especially all the amazing scientists involved with this work ??

The wheels of quantum manufacturing are turning! I'm excited for all the new partners around the world who will have our atomic entanglement sources and all the cool experiments they are planning to do with them ??

Cisco Quantum Summit was simply perfect! What an amazing line up of researchers, all so eager to push the state of distributed quantum networks together. This year the momentum is real. There are already quantum townhalls planned for Feb and June to take these partnerships to the next level and everyone is going to be involved. A huge thank you Reza Nejabati and the Outshift by Cisco team for hosting and bringing everyone together If you missed the event, I'm sure it will be available online soon.

You can still register to attend Cisco's quantum summit virtually and stay updated with the most recent progress in quantum networkingm And you certainly don't want to miss the invited talk by our Chief Scientist on how room temperature atoms are paving the path towards large scale distributed quantum networks!

Next week is the SPIE Photonics West and the PRIMS awards Gala. We are not only finalists in the quantum category for the third year in a row, but also the reigning champion after Qunnect's Qu-APC won the 2024 quantum award of the year. This year's nominee is very different though! After 5 years of research and development, we finally commercialized our first full stack product suite, the Gotham Rack. Designed for the upcoming scalable entanglement distribution infrastructures around the world, Gotham Rack has all the hardware and software needed to establish the most stable, highest rate, fully automated entanglement links. In 2024 we soft lunched this rack with the successful deployment of two units. This year, we are ready to work with any industry and testbed around the world who wants to create the foundation for quantum networks with capabilities from security all the way to distributed quantum computing and sensing. Welcome to the year of Quantum! Also kudos to Noel Goddard, Mark Tolbert, and Eden Valentin Figueroa Barragan for taking the coolest photo last year together ??

The international year of quantum science and technology is finally here ?? ?? Let's start the year with this comprehensive review article, summarizing how far the global quantum networking landscape has came. So many important milestones have been achieved in the past few years, paving the way towards large scale quantum networks. And I'm very thankful for their indepth inclusion of our work at GothamQ. The data for the GothamQ, showing how robust and reliable entanglement distribution in a real world setting can get was taken exactly last year this time. We paused the experiment when we got back to the hub after the holidays. This year we are starting our GothamQ work by expanding the network and demonstrating our multi node capabilities between Manhattan and Brooklyn. Stay tuned for the next papers ??

If you look around, you might think that most quantum startups grow because they span out of a famous university or a wellknown research group. Qunnect never had those privileges, spinning out of a state university and from a relatively unknown, young group. In fact, I was the first PhD graduate of that group. But none of that really decided our faith because we had that one privilege which mattered the most, the best quantum team in the world. People who stood together, through the hardest times, and against all odds pulled off some of the hardest milestones. This year alone we: ?? Won the PRISM award for our automated polarization compensation devices. ?? Published two peer-reviewed papers. ?? Demonstrated the most practical quantum entanglement network in the world. ?? Expanded GothamQ to a real data center in Manhattan. ?? Added two new products to our suit. ?? Generated more than $2M in sales revenue. ?? Deployed the world's first full solution Quantum rack for entanglement networks ?? Finalized CRADA and partnership with 3 Fortune500 companies and 2 major US agencies. And the list goes on and on. Qunnect is bringing quantum networking out of academia and delivering it directly to the end users globally. None of these things would have been possible without our team ??

We've made it to the SPIE PRISM award finale for the 3rd year in a row, this time as the reigning champion ?? Our Gotham Rack is a full entanglement solution, providing the entire hardware and software needed to create high rate, high fidelity, polarization entanglement networks, compatible with most atomic sensors and computers. See you at the PRISM Gala ??
