Could a new law of physics support the idea we’re living in a computer simulation?

Posted by in categories: computing, Elon Musk, physics

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.

Dial ‘M5’ for More …

Posted by in categories: computing, internet

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.

Asked if Intel can succeed in developing foundries and chips, AMD exec says, ‘Of course not’

Posted by in category: computing

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!

2010: The Year We Make Contact

In the year 2001, the spaceship Discovery is betrayed by its on-board computer, HAL, while on a mission to Jupiter. Nine years later, with the United States and Russia on the brink of war, the superpowers launch a joint mission to return to the Discovery in 2010: The Year We Make Contact. During the three-year voyage to Jupiter, world war breaks out on Earth, threatening to extend to the spaceship. But the ghostly presence of Dave Bowman (Keir Dullea) of the Discovery crew intervenes, warning that something grand, dangerous and wonderful is about to occur…

Scientists untangle mystery about the universe’s earliest galaxies

Posted by in categories: computing, cosmology

WASHINGTON, Oct 6 (Reuters) — Since beginning operations last year, the James Webb Space Telescope has provided an astonishing glimpse of the early history of our universe, spotting a collection of galaxies dating to the enigmatic epoch called cosmic dawn.

But the existence of what appear to be massive and mature galaxies during the universe’s infancy defied expectations — too big and too soon. That left scientists scrambling for an explanation while questioning the basic tenets of cosmology, the science of the origin and development of the universe. A new study may resolve the mystery without ripping up the textbooks.

The researchers used sophisticated computer simulations to model how the earliest galaxies evolved. These indicated that star formation unfolded differently in these galaxies in the first few hundred million years after the Big Bang event 13.8 billion years ago that initiated the universe than it does in large galaxies like our Milky Way populating the cosmos today.

Scientists create a novel quantum platform using atoms

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

The method is still at its basic stage but multiple such microscopes could be pooled up to build a larger quantum computer.

Researchers at the IBS Center for Quantum Nanoscience (QNS) in Seoul, South Korea, have successfully demonstrated using a scanning tunneling microscope (STM) to perform quantum computation using electrons as qubits, a press release said.

Quantum computing is usually associated with terms such as atom traps or superconductors that aid in isolating quantum states or qubits that serve as a basic unit of information. In many ways, everything in nature is quantum and can be used to perform quantum computations as long as we can isolate its quantum states.

Raspberry Pi 5 Launches in October With Upgraded Everything

Posted by in category: computing

Tinkerers, developers, and general-purpose nerds will be happy to hear that Raspberry Pi CEO Eben Upton was wrong about the Raspberry Pi 5. When asked about the foundation’s fifth-generation single-board computer late last year, Upton said we should not expect to see it in 2023. But surprise, the Raspberry Pi 5 is launching this month with a big performance boost and a reasonable price.


The new model, which will be much faster, starts at just $60 with 4GB of RAM.

Scientists develop a semi-device independent, randomness-free test for quantum correlation

Posted by in categories: computing, encryption, quantum physics

In a new Physical Review Letters study, scientists have successfully presented a proof of concept to demonstrate a randomness-free test for quantum correlations and non-projective measurements, offering a groundbreaking alternative to traditional quantum tests that rely on random inputs.

“Quantum correlation” is a fundamental phenomenon in and one that is central to quantum applications like communication, cryptography, computing, and information processing.

Bell’s inequality, or Bell’s theory, named after physicist John Stewart Bell, is the standard test used to determine the nature of correlation. However, one of the challenges with using Bell’s theorem is the requirement of seed for selecting measurement settings.

QBism and the philosophical crisis of quantum mechanics

Posted by in categories: computing, cosmology, quantum physics

The famous Copenhagen Interpretation favored by the founders of quantum mechanics is most definitely psi-epistemic. Niels Bohr, Werner Heisenberg, and others saw the state vector as being related to our interactions with the Universe. As Bohr said, “Physics is not about how the world is; it is about what we can say about the world.”

QBism is also definitively psi-epistemic, but it is not the Copenhagen Interpretation. Its epistemic focus grew organically from its founders’ work in quantum information science, which is arguably the most important development in quantum studies over the last 30 years. As physicists began thinking about quantum computers, they recognized that seeing the quantum in terms of information — an idea with strong epistemic grounding — provided new and powerful insights. By taking the information perspective seriously and asking, “Whose information?” the founders of QBism began a fundamentally new line of inquiry that, in the end, doesn’t require science fiction ideas like infinite parallel universes. That to me is one of its great strengths.

But, like all quantum interpretations, there is a price to be paid by QBism for its psi-epistemic perspective. The perfectly accessible, perfectly knowable Universe of classical physics is gone forever, no matter what interpretation you choose. We’ll dive into the price of QBism next time.

Quantum Leap: Physicists Successfully Simulate Super Diffusion

Posted by in categories: computing, particle physics, quantum physics

Quantum physicists have simulated super diffusion in quantum particles on a quantum computer, paving the way for deeper insights into condensed matter physics and materials science. This achievement, realized on a 27-qubit system programmed remotely from Dublin, emphasizes the potential of quantum computing in both commercial and fundamental physics inquiries.

Quantum physicists at Trinity, working alongside IBM Dublin, have successfully simulated super diffusion in a system of interacting quantum particles on a quantum computer.

This is the first step in doing highly challenging quantum transport calculations on quantum hardware and, as the hardware improves over time, such work promises to shed new light in condensed matter physics and materials science.
