  1. Google Modded Minecraft, Now Includes Quantum Physics

    Each time hoping that the next Minecraft mod, will be the Minecraft mod home.

    Quantum physics is complicated and hard to understand. Minecraft is popular, addictive, and fun to play. Combining the two may seem strange, but that's exactly what Google has done with their free qCraft mod for the game. It adds new blocks and features to introduce players to the world of quantum physics.

  2. In the Spin Zone: IBM Researchers Take Big Step Toward Quantum Computing

    Researchers have mapped the spin of electrons in a semiconductor for the first time, marking a big step forward in the march toward quantum computing. By synchronizing the subatomic particles, researchers were able to extend their spin lifetimes to just over 1 nanosecond. That's about the same time an existing computer processor takes to cycle, and offers proof of concept that quantum-based processors can remain stable long enough to encode information, according to a study published online this week in the journal Nature Physics.

  3. Tiny Quantum Computer Crystal Is As Powerful As A Digital Computer The Size Of The Universe

    Quantum computing is a big deal. Unlike cramming more and more components closer together on chips, quantum computing will increase processing power by orders of magnitude. It would forever change the face of computing as we know it. Still not hitting home? How about this: Scientists have designed a 300 atom quantum-computing crystal so powerful that in order for a conventional computer to match it, that computer would have to be the size of the known universe. Yeah.

  4. Scientists Establish First Working Quantum Network, Quantum Internet On The Way

    With amount of components we can cram on a chip slowly reaching its physical limit, quantum has become the next big thing that could revolutionize the computing world. IBM is even on the cusp of building actual quantum computer protoypes. But what good is any of that if we don't have a quantum Internet? Fortunately, we do. A team of scientists at the Max Planck Institute of Quantum Optics have just established the first working quantum network.

  5. IBM Makes New Breakthrough In Quantum Computing, On the Cusp of Designing Actual Prototypes

    Today, scientists at IBM have announced that they've achieved a breakthrough in quantum computing that may allow engineers to start working on actual quantum computer prototypes in the near future. To put it another way, up until now, quantum computing has largely been concerned with questions like "What kind of crazy stuff could we do if we had one of these?" and now thanks to this breakthrough, it's barreling towards something more like "Okay, let's figure out how to put one of these together."

  6. Diamonds Are A Quantum Computer's Best Friend

    Quantum computing is a new and exciting field, emerging from the ability to utilize quantum mechanics to create computers that can perform complex operations on data. Scientists have been making progress developing quantum computers and they know what is required to make such a system. Though they have developed working systems, scientists still believe that no existing machine has reached the full potential of quantum computing. The trend in quantum computing research is shifting away from proof-of-principle and focusing on trying to make a better way to control quantum bits (qubits) to perform operations. New research described in papers in Nature Physics by a team from the Center for Spintronics and Quantum Computation at the University of California, Santa Barbara and Physical Letters Review by a team from the Department of NanoBiophotonics at the Max Planck Institute for Biophysical Chemistry in Germany has found that impure diamonds may be an effective architecture for quantum computing.

  7. Actual Quantum Computing Performed: “Thousands of times” Faster Than Conventional Computer

    Japanese (who else?) scientists have used quantum calculation to compute a Fourier transform with an iodine molecule.

    From Popular Science:

    Using quantum interference – the vibrations of the atoms themselves – the team was able to run the complete discrete Fourier transform extremely quickly by encoding the inputs into an optically tailored vibrational wave packet which is then run through an excited iodine molecule whose atomic elements are oscillating at known intervals and picked up by a receiver on the other side. The entire process takes just a few tens of femtoseconds (that’s a quadrillionth of a second). So we’re not just talking faster data flow or processing here; these are speeds that are physically impossible on any kind of conventional electronic device.

    Uh...

    Can we still say its cool if we don't understand it at all?
