The Simulation Hypothesis: Is Reality All Just A Computer Simulation?
Posted by Andreas Matt in categories: computing, Elon Musk
In Brief As technology improves, the possibility that our world may be a simulated one is becoming more and more probable, argues Universe Today founder Fraser Cain. But can we ever prove that we live in a simulation of a reality?
All the world’s a stage. Or is it a simulation?

A New Kind of Computer Chip: Silicon May Be Replaced by New Material
Posted by Klaus Baldauf in categories: computing, materials
At the forefront of computing technology for decades, silicon-based chips’ reign may soon end, as today’s chip designers are looking for other materials that offer more options and more amazing abilities than the silicon we all know and love.
This new trend has spurred the guys at Oak Ridge National Laboratory (ORNL) to develop what could be the foundation for multi-role computer chips.

Does The Universe Have a Hard Drive?
Posted by Philip Raymond in categories: computing, cosmology, physics, quantum physics, supercomputing
Zura Kakushadze is lead author of this peer reviewed paper published by the Free University of Tbilisi. It describes an information paradox that arises in a materialist’s description of the Universe—if we assume that the Universe is 100% quantum. The observation of the paradox stems from an interdisciplinary thought process whereby the Universe can be viewed as a “quantum computer”.
The presentation is intentionally nontechnical to make it accessible to a wide a readership.

Fast track control accelerates switching of quantum bits
Posted by Karen Hurst in categories: computing, nanotechnology, quantum physics
From laptops to cellphones, technology advances through the ever-increasing speed at which electric charges are directed through circuits. Similarly, speeding up control over quantum states in atomic and nanoscale systems could lead to leaps for the emerging field of quantum technology.
An international collaboration between physicists at the University of Chicago, Argonne National Laboratory, McGill University, and the University of Konstanz recently demonstrated a new framework for faster control of a quantum bit. First published online Nov. 28, 2016, in Nature Physics, their experiments on a single electron in a diamond chip could create quantum devices that are less prone to errors when operated at high speeds.

Accessible Photon Emission Could Bring Quantum Computing Out of the Lab
Posted by Karen Hurst in categories: computing, information science, internet, mobile phones, quantum physics
Researchers from the Tyndall National Institute in Cork have created micro-structures shaped like small pyramids that can create entangled photons. Does this mean that quantum computers are closer than we realize?
Quantum computers have been the stuff of science fiction for the past few decades. In recent times, quantum computers have slowly become more of a reality with some machines successfully solving real world problems such as games and path finding algorithms.
But why are quantum computers so desired by tech firms and why is there so much research into the field? Silicon has been incredibly loyal to the tech world for the past 50 years, giving us the point contact transistor in 1947. Now, silicon is at the center of technology with computers, tablets, smartphones, the IoT, and even everyday items. In fact, you cannot walk down a city street without being in range of some Wi-Fi network or influence from a small silicon device.

Macaque monkeys have the anatomy for human speech, so why can’t they speak?
Posted by Sean Brazell in categories: computing, neuroscience
While they have a speech-ready vocal tract, primates can’t speak because they lack a speech-ready brain, contrary to widespread opinion that they are limited by anatomy, researchers at Princeton University and associates have reported Dec. 9 in the open-access journal Science Advances.
The researchers reached this conclusion by first recording X-ray videos showing the movements of the different parts of a macaque’s vocal anatomy — such as the tongue, lips and larynx. They then converted that data into a computer model that could predict and simulate a macaque’s vocal range.

Light based microchips are the future of electronics
Posted by Klaus Baldauf in categories: computing, futurism
For the past four decades, the electronics industry has been driven by what is called “Moore’s Law,” which is not a law but more an axiom or observation. Effectively, it suggests that the electronic devices double in speed and capability about every two years. And indeed, every year tech companies come up with new, faster, smarter and better gadgets.
Specifically, Moore’s Law, as articulated by Intel cofounder Gordon Moore, is that “The number of transistors incorporated in a chip will approximately double every 24 months.” Transistors, tiny electrical switches, are the fundamental unit that drives all the electronic gadgets we can think of. As they get smaller, they also get faster and consume less electricity to operate.
In the technology world, one of the biggest questions of the 21st century is: How small can we make transistors? If there is a limit to how tiny they can get, we might reach a point at which we can no longer continue to make smaller, more powerful, more efficient devices. It’s an industry with more than US$200 billion in annual revenue in the U.S. alone. Might it stop growing?

Two electrons go on a quantum walk and end up in a qudit: Russian scientists find a way to reliably connect quantum elements
Posted by Karen Hurst in categories: biotech/medical, computing, nanotechnology, particle physics, quantum physics, solar power, sustainability
This is a BIG DEAL in QC, and Russian Scientists solved it.
Abstract: Scientists from the Institute of Physics and Technology of the Russian Academy of Sciences and MIPT have let two electrons loose in a system of quantum dots to create a quantum computer memory cell of a higher dimension than a qubit (a quantum bit). In their study published in Scientific Reports, the researchers demonstrate for the first time how quantum walks of several electrons can help to implement quantum computation.
“By studying the system with two electrons, we solved the problems faced in the general case of two identical interacting particles. This paves the way toward compact high-level quantum structures,” comments Leonid Fedichkin, Expert at the Russian Academy of Sciences, Vice-Director for Science at NIX (a Russian computer company), and Associate Professor at MIPT’s Department of Theoretical Physics.
