Manipulating photons for microseconds tops 9,000 years on a supercomputer
Posted by Quinn Sena in categories: quantum physics, supercomputing
Ars Technica’s Chris Lee has spent a good portion of his adult life playing with lasers, so he’s a big fan of photon-based quantum computing. Even as various forms of physical hardware like superconducting wires and trapped ions made progress, it was possible to find him gushing about an optical quantum computer put together by a Canadian startup called Xanadu. But, in the year since Xanadu described its hardware, companies using that other technology continued to make progress by cutting down error rates, exploring new technologies, and upping the qubit count.
But the advantage of optical quantum computing didn’t go away, and now Xanadu is back with a reminder that it still hasn’t gone away. Thanks to some tweaks to the design it described a year ago, Xanadu is now able to sometimes perform operations with more than 200 qubits. And it has shown that simulating the behavior of just one of those operations on a supercomputer would take 9,000 years, while its optical quantum computer can do them in just a few-dozen milliseconds.
This is an entirely contrived benchmark: Just as Google’s quantum computer did, the quantum computer is just being itself while the supercomputer is trying to simulate it. The news here is more about the potential of Xanadu’s hardware to scale.

World’s first exascale supercomputer Frontier smashes speed records
Posted by Jose Ruben Rodriguez Fuentes in categories: biotech/medical, supercomputing
The world’s first exascale computer, capable of performing a billion billion operations per second, has been built by Oak Ridge National Laboratory (ORNL) in the US.
A typical laptop is only capable of a few teraflops, or a trillion operations per second, which is a million times less. The exaflop machine, called Frontier, could help solve a range of complex scientific problems, such as accurate climate modelling, nuclear fusion simulation and drug discovery.
“Frontier will offer modelling and simulation capabilities at the highest level of computing performance,” says Thomas Zacharia at ORNL.

Frontier supercomputer powered by AMD is the fastest in the world
Posted by Jose Ruben Rodriguez Fuentes in category: supercomputing
The AMD-powered Frontier supercomputer at Oak Ridge National Laboratory has bagged the top spot on the Top500 list of the world’s fastest supercomputers. The Top500 list also said that the Frontier system is the first true exascale machine with an HPL score of 1.102 Exaflop/s. For two years, the top spot was occupied by the Fugaku system at the RIKEN Center for Computational Science (R-CCS) in Kobe, Japan.
Based on the latest HPE Cray EX235a architecture and equipped with AMD EPYC 64C 2GHz processors, the system has 8,730,112 total cores and a power efficiency rating of 52.23 gigaflops/watt. It relies on gigabit ethernet for data transfer.

US retakes first place from Japan on Top500 supercomputer ranking
Posted by Dan Kummer in categories: military, supercomputing
ORNL’s Frontier HPE Cray EX with AMD CPUs is the ‘first true exascale machine.’
The United States is on top of the supercomputing world in the Top500 ranking of the most powerful systems. The Frontier system from Oak Ridge National Laboratory (ORNL) running on AMD EPYC CPUs took first place from last year’s champ, Japan’s ARM A64X Fugaku system. It’s still in the integration and testing process at the ORNL in Tennessee, but will eventually be operated by the US Air Force and US Department of Energy.
Frontier, powered by Hewlett Packard Enterprise’s (HPE) Cray EX platform, was the top machine by a wide margin, too. It’s the first (known) true exascale system, hitting a peak 1.1 exaflops on the Linmark benchmark. Fugaku, meanwhile, managed less than half that at 442 petaflops, which was still enough to keep it in first place for the previous two years.

Revolutionary New Qubit Platform Could Transform Quantum Computing
Posted by Saúl Morales Rodriguéz in categories: engineering, quantum physics, supercomputing
The digital device you are using to view this article is no doubt using the bit, which can either be 0 or 1, as its basic unit of information. However, scientists around the world are racing to develop a new kind of computer based on the use of quantum bits, or qubits, which can simultaneously be 0 and 1 and could one day solve complex problems beyond any classical supercomputers.
A research team led by scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, in close collaboration with FAMU-FSU College of Engineering Associate Professor of Mechanical Engineering Wei Guo, has announced the creation of a new qubit platform that shows great promise to be developed into future quantum computers. Their work is published in the journal Nature.
“Quantum computers could be a revolutionary tool for performing calculations that are practically impossible for classical computers, but there is still work to do to make them reality,” said Guo, a paper co-author. “With this research, we think we have a breakthrough that goes a long way toward making qubits that help realize this technology’s potential.”
