This week’s great tech stories from around the web (until June 4th)


Processing microsecond photons tops 9,000 years on a supercomputer
John Timmer | Ars Technica
Thanks to some modifications to the design he described a year ago, [quantum computing startup] Xanadu is now sometimes able to perform operations with more than 200 qubits. It showed that it would take 9,000 years to simulate the behavior of just one of those processes on a supercomputer, while an optical quantum computer could do it in a few tens of a thousandth of a second.”


Researchers in Japan have set an astonishing new speed record for data transfers
Andrew Leszewski | Gizmodo
Researchers from Japan’s National Institute of Information and Communications Technology (NICT) have successfully transmitted data over a dedicated multi-core fiber optic cable at 1.02 petabits per second over a distance of 51.7 km. This equates to sending 127,500 gigabytes of data every second, which, according to the researchers, is also enough capacity for more than “10 million 8K channels per second.”I


California allows driverless taxi service to operate in San Francisco
Associated Press | Watchman
Cruise and another robotic car pioneer, Waymo, have already charged passengers for rides in parts of San Francisco in self-driving vehicles with a back-up human driver in control should something go wrong with the technology. But now Cruise has been allowed to charge for trips in vehicles that they It won’t have other people besides the passengers – an aspiration that a diverse group of tech companies and traditional automakers have been pursuing for more than a decade.”


With the glass buried under the ice, Microsoft plans to keep music for 10,000 years
Mark Wilson | fast company
“It is located in Norway, and is part of a cold storage facility dug into the exact same mountain as the Svalbard Global Seed Vault. While the seed vault protects the seed cache in the ground, the Global Music Vault aims to preserve the vocal arts for future generations. … It’s called Project Silica. , you can simplify [Microsoft’s] Technology as something similar to a glass hard drive that reads like a CD. It’s a 3-by-3-inch dish that can hold 100GB of digital data, or roughly 20,000 songs, forever. “


“How do you decide?” CAR-T Cancer Treatment Crisis Leads to Death of Patients on a Waiting List
Angus Chen | stat
By the fall of 2021, Patel saw only one possibility left to save Goultzini’s life – a newly approved CAR-T-cell therapy for myeloma. … It’s an approach that is transforming the treatment of blood cancers: CAR-T therapy labs turns the immune system’s T cells into a cancer cell killer by introducing a gene for what’s known as the chimeric antigen receptor. But the process is slow and arduous, and drugmakers can’t keep up.”

How do you make the universe think of us?
Charlie Wood | Quanta
Physicists are building neural networks from vibrations, voltages, and lasers, arguing that the future of computing lies in exploiting the complex physical behaviors of the universe. … McMahon finds his hardware amazing, albeit modest, proof that you don’t need a brain or a computer chip to think. “Any physical system can be a neural network,” he said.

AstroForge aims to succeed where other asteroid mining companies have failed
Eric Berger | Ars Technica
“…the company plans to build and launch what Gialich described as a “small” spacecraft to a near-Earth asteroid to extract regolith, purify that material and send it back toward Earth on a ballistic trajectory. It then flies into Earth’s atmosphere with a small heat shield and descends under a parachute. . …Acain and Gialich, spaceX and Virgin Orbit veterans, respectively, readily concede that what they’re proposing is somewhat bold. But they believe it is time for commercial companies to start looking beyond low Earth orbit” .


Brain tapping with 10,000 electrodes
Baron Dutta | IEEE Spectrum
“Version 2.0 of [Neuropixels] The system, which was shown last year, increases the number of sensors by about an order of magnitude compared to the initial version produced just four years ago. It paves the way for future brain-computer interfaces that may enable paralyzed people to communicate at speeds approaching the speed of normal conversation. With version 3.0 already in early development, we believe Neuropixels is at the beginning of a long path of exponential growth in capabilities similar to Moore’s Law.”
