Europe is pushing to create a network infrastructure based on quantum physics.

In May 2023, Dr. Benjamin Lanyon at the University of Innsbruck in Austria took an important step toward creating a new kind of internet: he transferred information along an optical fiber 50 kilometers long using the principles of quantum physics.

Information in quantum physics differs from the units of data—binary digits—stored and processed by computers that form the core of the current World Wide Web. The quantum physics realm covers the properties and interactions of molecules, atoms and even such as electrons and photons.

Researchers have developed a method that can reveal the location of errors in quantum computers, making them up to 10 times easier to correct. This will significantly accelerate progress towards large-scale quantum computers capable of tackling the world’s most challenging computational problems, the researchers said.

Led by Princeton University’s Jeff Thompson, the team demonstrated a way to identify when errors occur in quantum computers more easily than ever before. This is a new direction for research into quantum computing hardware, which more often seeks to simply lower the probability of an error occurring in the first place.

A paper detailing the new approach was published in Nature on Oct. 11. Thompson’s collaborators include Shruti Puri at Yale University and Guido Pupillo at Strasbourg University.

The concept that we are all computer-generated characters occupying a world as real as the ones gamers explore on their PlayStation consoles isn’t exactly a new one.

As far back as 1999, Morpheus was entering “The Matrix” to break Neo and a few other chosen few out of a simulated reality created by advanced machines in order to use humans as an energy source. But as the idea permeates not just the realm of science fiction and popular culture, but academia as well, every now and then a philosopher or physicist has something new to say about it.

That’s what happened this week when a physicist at the University of Portsmouth in the United Kingdom proposed that a new law of physics could support the theory that what we see as our reality is in fact a complex virtual simulation running on a cosmic computer. The theory stems from previous research that Dr. Melvin Vopson has conducted looking into whether information has mass.

Microsoft flagged two zero-day security vulnerabilities under active attack in October’s Patch Tuesday update, which affect Microsoft WordPad and Skype for Business. The release also features a critical-rated, wormable bug in Message Queuing that could instill terror for admins of vulnerable systems.

The two bugs are part of a cadre of 103 total CVEs addressed by the computing giant this month. The patches run the gamut of Microsoft’s portfolio, including Azure, ASP.NET, Core, and Visual Studio; Exchange Server; Office, Microsoft Dynamics, and Windows.

Appropriately for October, the number of critical-rated vulnerabilities comes in at an unlucky 13; and notably, a full 20% of the fixes in the update relate to Microsoft Message Queuing (MSMQ).

The scent of coffee. The clarity of sunlight dappling through the trees. The howl of the wind in the dark of night.

All this, according to a philosophical argument published in 2003, could be no more real than pixels on a screen. It’s called the simulation hypothesis, and it proposes that if humanity lives to see a day it can repeatedly simulate the Universe using come kind of computer, chances are we are living in one of those many simulations.

If so, everything we experience is a model of something else, removed from some kind of reality.

Caltech researchers have discovered Hubbard excitons, which are excitons bound magnetically, offering new avenues for exciton-based technological applications.

In art, the negative space in a painting can be just as important as the painting itself. Something similar is true in insulating materials, where the empty spaces left behind by missing electrons play a crucial role in determining the material’s properties. When a negatively charged electron is excited by light, it leaves behind a positive hole. Because the hole and the electron are oppositely charged, they are attracted to each other and form a bond. The resulting pair, which is short-lived, is known as an exciton [pronounced exit-tawn].

Excitons are integral to many technologies, such as solar panels, photodetectors, and sensors. They are also a key part of light-emitting diodes found in televisions and digital display screens. In most cases, the exciton pairs are bound by electrical, or electrostatic, forces, also known as Coulomb interactions.

A University of Portsmouth physicist has explored whether a new law of physics could support the much-debated theory that we are simply characters in an advanced virtual world.

The simulated hypothesis proposes that what humans experience is actually an artificial reality, much like a computer simulation, in which they themselves are constructs.

The theory is popular among a number of well-known figures including Elon Musk, and within a branch of science known as information , which suggests is fundamentally made up of bits of information.

The M5Dial features a 1.28-inch round TFT touchscreen, a rotary encoder, an RFID detection module, an RTC circuit, a buzzer, and under-screen buttons, enabling users to easily implement a wide range of creative projects.

The main controller of M5Dial is M5StampS3, a micro module based on the ESP32-S3 chip known for its high performance and low power consumption. It supports Wi-Fi, as well as various peripheral interfaces such as SPI, I2C, UART, ADC, and more. M5StampS3 also comes with 8MB of built-in Flash, providing sufficient storage space for users.

Intel has been in the semiconductor chip manufacturing game for a while. Recently, it’s been looking to expand its foundries and production to the point where it could make cutting-edge chips for other companies, a territory we normally associate with TSMC and Samsung.

Currently, Intel is building and ramping up manufacturing in North America, Mexico, and Germany — and these foundries will be doing a lot more than simply creating chips for the latest generation of Core processors. Earlier this year, Intel and Arm announced a partnership to build mobile SoCs on Intel’s 18A process node, and we’ve even heard from the likes of NVIDIA stating that it’s open to working with Intel to produce its hardware.

All of this makes the recent statement from Darren Grasby, the executive vice president for strategic partnerships and president of AMD EMEA, a little shocking. His words were harsh when asked if Intel would succeed in its ambitious plans to build global foundries and develop and create chips for multiple companies. To say the least!

Some harsh words from an AMD exec who doesn’t think Intel’s global foundry expansion and semiconductor manufacturing will drum up new customers.
