We have quantum computers—now Amazon and Harvard want a quantum internet

Posted by in categories: computing, internet, nanotechnology, quantum physics

Two big players in computing and research are trying to lay the groundwork for a future quantum internet.

Amazon Web Services (AWS) is teaming up with Harvard University to test and develop strategies for networking together quantum technologies. Their partnership was announced today, and is a continuation of AWS’ goals to create a communications channel between the quantum computers that it is also working on in parallel.

During the three-year research alliance, funding from Amazon will support research projects at Harvard that focus on quantum memory, integrated photonics, and quantum materials, and help upgrade infrastructure in Harvard’s Center for Nanoscale Systems.

Can we reverse engineer the brain like a computer?

Circa 2019 face_with_colon_three

By Tyler Benster.

Neuroscientists have a dizzying array of methods to listen in on hundreds or even thousands of neurons in the brain and have even developed tools to manipulate the activity of individual cells. Will this unprecedented access to the brain allow us to finally crack the mystery of how it works? In 2017, Jonas and Kording published a controversial research article, “Could a Neuroscientist Understand a Microprocessor?” that argues maybe not. To make their point, the authors turn to their “model organism” of choice: a MOS 6502 processor as popularized by the Apple I, Commodore 64, and Atari Video Game System. Jonas and Kording argue that for an electrical engineer, a satisfying description of the processor would break it into modules, like an adder or subtractor, and submodules, like the transistor, to form a hierarchy of information processing. They suggest that, while popular methods from neuroscience might reveal interesting structure in the activity of the brain, researchers often use techniques that would fail to reveal a hierarchy of information processing if applied to the (presumably much simpler) computer processor.

Making mini-magnets that induce a quantum anomalous Hall effect

Posted by in categories: computing, quantum physics

A new device has been fabricated that can demonstrate the quantum anomalous Hall effect, in which tiny, discrete voltage steps are generated by an external magnetic field. This work may enable extremely low-power electronics, as well as future quantum computers.

If you take an ordinary wire with running through it, you can create a new electrical voltage perpendicular to the flow of current by applying an . This so-called Hall effect has been used as part of a simple magnetic sensor, but the sensitivity can be low.

There is a corresponding quantum version, called the quantum anomalous Hall effect that comes in defined increments, or quanta. This has raised the possibility of using the quantum anomalous Hall effect for the purpose of constructing new highly conductive wires or even quantum computers. However, the physics that leads to this phenomenon is still not completely understood.

NASA, Microchip, SiFive Announces Partnership for RISC-V Spaceflight Computing Platform

Posted by in categories: computing, space travel

NASA — National Aeronautics and Space Administration has tapped SiFive and Microchip Technology Inc. to create a space-centric RISC-V processor: the High-Performance Spaceflight Computing chip. At heart of the HPSC will be SiFive’s X280 64-bit RISC-V cores, which include ML acceleration capabilities.

Designed to replace existing systems still using a processor design from 1997, the RISC-V-powered chip will offer 100 times the performance.

Scientists Discover a Molecular Switch That Controls Life Expectancy

Posted by in categories: biotech/medical, computing, life extension


According to recent research, the protein CHIP can control the insulin receptor more effectively while acting alone than when in a paired state. In cellular stress situations, CHIP often appears as a homodimer – an association of two identical proteins – and mainly functions to destroy misfolded and defective proteins. CHIP thus cleanses the cell. In order to do this, CHIP works with helper proteins to bind a chain of the small protein ubiquitin to misfolded proteins.

As a result, the cell detects and gets rid of defective proteins. Furthermore, CHIP controls insulin receptor signal transduction. CHIP binds to the receptor and degrades it, preventing the activation of life-extending gene products.

No knowledge, only intuition!

Article originally published on LINKtoLEADERS under the Portuguese title “Sem saber ler nem escrever!”

In the 80s, “with no knowledge, only intuition”, I discovered the world of computing. I believed computers could do everything, as if it were an electronic God. But when I asked the TIMEX Sinclair 1000 to draw the planet Saturn — I am fascinated by this planet, maybe because it has rings —, I only glimpse a strange message on the black and white TV:
