University of NSW develop a quantum bit using the nucleus of an atom

From the University of New South Wales (UNSW): engineers have been able to use the nucleus of an atom as the basis for a quantum bit (or qubit) the fundamental unit of quantum computing. Why is this important? Quantum computing means a potentially massive (like, exponentiallymassive) increase in computing speed and capacity. This UNSW experiment was done […]

Cloud quantum computing could be just as secure

Cloud computing is using (possibly renting) computing power elsewhere via the internet. Quantum computing is using the seemingly-odd behaviour of quantum mechanics to do computations in parallel, thereby multiplying computing speeds. Some dudes have written a paper about research they’re doing into whether quantum computers could do calculations in the cloud securely. That is pretty […]

Rules of Physics in Quantum World Change When Applied to Classical World

From ScienceDaily: In a study published in the July 1 issue of the journal Nature, Associate Professor of Physics and Astronomy Alex Rimberg and his colleagues describe one example of the microscopic quantum world influencing, even dominating they say, the behavior of something in the macroscopic classical world. They used tiny semiconducting crystals that contain two […]

Quantum Dots For Future Computing Power?

There’s a great article in ScienceDaily about what might be an important step in computing power and efficiency. Many people are familiar – at least in principle – with the fact that computers work by integrated circuits made of the semiconductor silicon. Those integrated circuits of silicon contain transistors, because one of the things you […]

Quantum mechanics: context does matter

I’ve blathered on about quantum mechanics enough to make clear – if it wasn’t already – that it’s deeply non-intuitive stuff. One way that some thinkers (including Einstein) try to get around the apparently statistical (they felt, random) nature of quantum behaviour is viahidden variables. This theory is that there are other factors, or laws, […]

Scientists create first electronic quantum processor

From breaking science news site Eurekalert: A team led by Yale University researchers has created the first rudimentary solid-state quantum processor, taking another step toward the ultimate dream of building a quantum computer. They also used the two-qubit superconducting chip to successfully run elementary algorithms, such as a simple search, demonstrating quantum information processing with […]

Quantum computing: new methods for removing error

From ScienceDaily: Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a technique for efficiently suppressing errors in quantum computers. The advance could eventually make it much easier to build useful versions of these potentially powerful but highly fragile machines, which theoretically could solve important problems that are intractable using today’s computers. […]

Molecular machines may replace silicon chips for quantum computers

From the BBC recently: Edinburgh and Manchester University researchers have created a molecular device which could act as a building block for super-fast computers. Hi! I’m not really here right now. I’m on vacation in Australia. Through the magic of scheduled blogging, I’ve set a little something I find interesting to be posted each day […]
