Photonics

The scientific results just published in the new issue of the journal Nature Photonics represents another “first” in the technological achievements of the quantum computing company Quandela, towards the development of photonic quantum computers. Within a collaborative effort, several academic research groups (Pascale Senellart at C2N-CNRS, Sophia Economou at Virginia…

SRI researchers hope to compete with quantum computing by applying new algorithms to map large problems onto faster, more energy-efficient photonic circuitry. — Some problems are so complex that even the world’s fastest supercomputers take far too long to be cost-effective or practical. Many problems share this property of computational complexity. …

Photonics is coming to the rescue — Data centers — buildings full of computers that run all these applications you use on a daily basis from your preferred electronic devices, including what you’re using right now as you’re reading this, as well as more and more business and government applications — are estimated to consume about one…

NTT Research, a branch of conglomerate parent firm NTT, last week announced that it would expand the size of its optical research center by 2023. During its Upgrade 2023 event, the company’s technical user, customer, and partner conference in San Francisco, NTT proffered an expansive view of how it believes…

Driving quantum materials into non-equilibrium novel quantum phases using light-matter interactions… — The mesmerizing interplay between radiation and matter is at the heart of modern engineering and applied science. This dynamic discipline has taken the world of physics by storm, permeating various fields such as optical, molecular, and atomic physics, condensed matter physics, molecular biology, electrical engineering, medicine, and even quantum field…

Today I read that it costs Google about 1.06 cents to run a search query (including indirect costs), on which it generates 1.61 cents of revenue. According to some rough calculations, a ChatGPT query would cost ~0.36 cents. So a naive integration/addition of ChatGPT-like results into Google would be devastating…

12-Mode “Ascella” Photonic Quantum Computer I recently started playing with Quandela’s 12-mode “Ascella” photonic quantum computer, and I’m here to report The Good, The Bad, and The Ugly about it. Spoiler alert, though: almost all of this article is under The Good. The Good Fast. I submitted almost three dozen jobs the other day, split between the…

It’s past time to deep dive photonics. It turns out that photonics is no harder than working with any other type of qubit. If you play with the operations enough, you can eventually get a good feel for what they do and how photonics compares to, for example, superconducting quantum computing. …

As the year comes to an end, we reflect on all that the team here at Lightmatter has accomplished in 2022. We’ve grown as a company, made strides in progressing our product line, and are thrilled to have received so much recognition. We have assembled a list of some of…
