A Biological Transistor

Biological transistor enables computing within living cells | Engineering

A team of Stanford University bioengineers has taken computing beyond mechanics and electronics into the living realm of biology. They have developed a biological transistor made from genetic material — DNA and RNA. The team calls its invention the “transcriptor.”



Scientists create transistor-like biological device | Science | The Guardian

The biological device behaves like a transistor, one of the tiny switches that are etched on to microchips in the billions to perform computer calculations.

The researchers demonstrated the device inside E coli bacteria, one of the most common bugs used in genetic engineering. The work marks one of the latest advances in the growing field of synthetic biology, which recasts biology as a toolset for engineers.

Ultrafast Computing with Laser-Driven-Molecules

Quantum Experiment Brings Us Closer To Super-Fast Computers


Computing a Fourier transform isn’t so hard. You know, that common calculation that uses spectral analysis and data compression. But just try doing it with an iodine molecule. Japanese scientists did, of course, and succeeded.


A Single Molecule Computes Thousands of Times Faster than Your PC

A demo of a quantum calculation carried out by Japanese researchers has yielded some pretty mind-blowing results: a single molecule can perform a complex calculation thousands of times faster than a conventional computer.

A proof-of-principle test run of a discrete Fourier transform -- a common calculation using spectral analysis and data compression, among other things -- performed with a single iodine molecule transpired very well, putting all the molecules in your PC to shame.

[...] Writing in Physical Review Letters, Kouichi Hosaka [3] and collaborators from several institutions in Japan illustrate how quantum interference may be used to execute a common classical algorithm very rapidly—within a few tens of femtoseconds. Hosaka et al. demonstrate that the dynamics associated with the vibrations of the atoms in a molecule can be used to implement a Fourier transform. The rapidity of the molecular oscillations means that this protocol can be executed very quickly—much quicker, as the authors point out, than any conceivable device based on conventional electronics.

The authors point out the important feature that the molecular motion executes the Fourier transform in a mere 145 fs. This is several orders of magnitude faster than devices based on silicon electronics are likely to be able to achieve. This observation provokes an enticing proposition—the idea of high-speed, nondissipative logic operations and algorithms would make for a revolution in physical instantiations of computational devices.

However, there are a number of important barriers that will need to be overcome if such devices are to displace current high-speed electronics.
[...]
Nonetheless, the notion of a classical processor with such a dramatic speed-up suggests that it is worth continuing to explore new ways to use physical systems to encode and manipulate information, and that this connection may reveal new insights into both physics and into information processing.

First Universal Programmable Quantum Computer

Scientists Test First Universal Programmable Quantum Computer

Physicists have been taking baby steps toward creating a full-fledged quantum computer faster and more powerful than any computer in existence, by making quantum processors capable of performing individual tasks. Now a group at the National Institute of Standards and Technology (NIST) has developed the world's first universal programmable quantum computer that can run any program that's possible under the rules of quantum mechanics.

First Universal Two-Qubit quantum processor created

qbit

This processor could prove to be a major breakthrough for a future quantum computer, that could very well be the ‘evolutionary leap’ in the computers’ life thus resulting the possible solve of problems that are untouchable today. The discovery was presented in the latest edition of Nature Physics and this marks the first time anybody has moved beyond asking a single task from a quantum computer.

NIST postdoctoral researcher David Hanneke at the laser table used to demonstrate the first universal programmable processor for a potential quantum computer. A pair of beryllium ions (charged atoms) that hold information in the processor are trapped inside the cylinder at the lower right. A colorized image of the two ions is displayed on the monitor in the background.

“This is the first time anyone has demonstrated a programmable quantum processor for more than one qubit,” says NIST postdoctoral researcher David Hanneke, first author of the paper. “It’s a step toward the big goal of doing calculations with lots and lots of qubits. The idea is you’d have lots of these processors, and you’d link them together.

The NIST processor stores binary information (1s and 0s) in two beryllium ions (electrically charged atoms), which are held in an electromagnetic trap and manipulated with ultraviolet lasers. Two magnesium ions in the trap help cool the beryllium ions.

NIST scientists can manipulate the states of each beryllium qubit, including placing the ions in a “superposition” of both 1 and 0 values at the same time, a significant potential advantage of information processing in the quantum world. Scientists also can “entangle” the two qubits, a quantum phenomenon that links the pair’s properties even when the ions are physically separated.

The Mandelbulb a 3D Mandelbrot Set

clipped from en.wikipedia.org
Fractal
A fractal is "a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole,"[1] a property called self-similarity.

The Mandelbrot set is a famous example of a fractal

The Real 3D Mandelbulb

It's found by following a relatively simple math formula. But in the end, it's still only 2D and flat - there's no depth, shadows, perspective, or light sourcing. What we have featured in this article is a potential 3D version of the same fractal.

Resulting renders

But it wasn't until I incorporated proper shadowing that the subtleties of this incredible object became apparent. For the renders below and exploration afterwards,

Cloud Computing in Plain English

clipped from en.wikipedia.org
Cloud computing

From Wikipedia, the free encyclopedia

Cloud computing refers to the delivery of computational resources from a location other than your current one. In its most used context it is Internet-based ("cloud") development and use of computer technology ("computing"). The cloud is a metaphor for the Internet, based on how it is depicted in computer network diagrams, and is an abstraction for the complex infrastructure it conceals.[1]
