Neuromorphic photonics is an emerging computing platform that addresses the growing computational demands of modern society. We review advances in integrated neuromorphic photonics and discuss challenges associated with electro-optical conversions, implementations of nonlinearity, amplification and processing in the time domain.
When element 61, also known as promethium, was first isolated by scientists at the Department of Energy’s Oak Ridge National Laboratory in 1945, it completed the series of chemical elements known as lanthanides. However, aspects of the element’s exact chemical nature have remained a mystery until last year, when a team of scientists from ORNL and the National Institute of Standards and Technology used a combination of experimentation and computer simulation to purify the promethium radionuclide and synthesize a coordination complex that was characterized for the first time. The results of their work were recently published in Nature.
For every kilogram of matter that we can see—from the computer on your desk to distant stars and galaxies—there are 5 kilograms of invisible matter that suffuse our surroundings. This “dark matter” is a mysterious entity that evades all forms of direct observation yet makes its presence felt through its invisible pull on visible objects.
Vortices are a common physical phenomenon. You find them in the structure of galaxies, tornadoes and hurricanes, as well as in a cup of tea, or water as it drains from the bathtub.
Actually, nothing is wrong with it if you are a computer science major. It’s just that it has no place in the philosophy department.
From the point of anyone wanting to work in natural language, symbolic logic has all of the vices of mathematics and none of its virtues. That is, it is obscure to the point of incomprehensibility (given the weak neurons of this English major at any rate), and it leads to no useful outcome in the domain of human affairs. This would not be so bad were it not for all those philosophy major curricula that ask freshmen to take a course in it as their “introduction” to philosophy. For anyone looking to explore the meaning of life, this is a complete turnoff.
We propose and demonstrate the first chip-based 3D printer, consisting of a silicon-photonics chip that emits non-mechanically-reconfigurable beams into photocurable resin, enabling future compact, portable, and low-cost next-generation 3D printers.
Imagine a portable 3D printer you could hold in the palm of your hand. The tiny device could enable a user to rapidly create customized, low-cost objects on the go, like a fastener to repair a wobbly bicycle wheel or a component for a critical medical operation.
It seems like over the past few years, Quantum is being talked about more and more. We’re hearing words like qubits, entanglement, super position, and quantum computing. But what does that mean … and is quantum science really that big of a deal? Yeah, it is.
It’s because Quantum science has the potential to revolutionize our world. From processing data to predicting weather, to picking stocks or even discovering new medical drugs. Quantum, specifically quantum computers, could solve countless problems.
Dr. Heather Masson-Forsythe, an AAAS Science \& Technology Fellow in NSF’s Directorate for Computer and Information Science and Engineering, hosts this future-forward episode.
Featured guests include (in order of appearance): Dr. Spiros Michalakis, the manager of outreach and a staff researcher at Caltech’s Institute for Quantum Information and Matter, an NSF Physics Frontiers Center.
Dolev Bluvstein, a doctoral student at Harvard University, working in the Lukin Group at the Quantum Optics Laboratory.
Dr. Scott Aaronson, Schlumberger Chair of Computer Science at The University of Texas at Austin and director of its Quantum Information Center.
