Spy Agency Bets on IBM for Universal Quantum Computing A real-life U.S. version of “Q Branch” from the James Bond films has greater ambitions than creating personal spy gadgets such as exploding watches or weaponized Aston Martins. It’s betting on an IBM team to develop the first logical qubits as crucial building blocks for universal quantum computers capable of outperforming today’s classical computers. Most quantum computing efforts have focused on building ever-larger arrays of quantum bits, called qubits, made from physical components such as superconducting loops of metal or charged atoms trapped within magnetic fields. Qubits can  harness the weird power of quantum physics to  exist in two states simultaneously and influence distant qubits through quantum entanglement, but the challenge comes from maintaining fragile quantum states long enough to perform computer calculations. As a next step, the U.S. Intelligence Advanced Researc...

Theory Lowers the Speed Limit for Quantum Computing Today’s quantum computing systems have just begun hinting at how future versions might outperform classical computers at solving certain complex problems. But new research has lowered the theoretical speed limit that future quantum computers will eventually run up against. Quantum computing systems have the potential to perform certain calculations much faster than classical computers by using quantum bits, or qubits—things that rely on the phenomenon known as superposition to represent information as both 1 and 0 at the same time. Such systems could also  exploit another physical phenomenon known as quantum entanglement. In entanglement, a single qubit shares its information state with many other qubits through quantum connections. But t he latest calculations by the U.S. National Institute of Standards and Technology place a new speed limit on how...

In a Nutshell - Kurzgesagt Watch: This is quantum computing in a nutshell Here's why superposition is a total game changer.  BEC CREW 9 DEC 2015       The exponential growth of computing technology from the 1960s and '70s to now is one of the greatest achievements of modern science. But it doesn't really matter how far we've come if we're about to hit the limit for what we can accomplish. Our computers might be pretty awesome already, but the parts we've been reliant on have just about hit their physical limits - they're approaching the size of an atom, and it doesn't get much smaller than that. So what's next? Well we're figuring out how to fight quantum physics with quantum physics to build the computers of the future,   and this video by Kurzgesagt   is here to explain how. First up, if we're going to understand the conundrum that we're in, thanks to the physical limits of our current...

The Verge Watch: Quantum computing explained in less than 2 minutes Now you can explain it to your friends. BEC CREW 18 OCT 2015       For decades now, scientists have been trying to figure out how we can use the enormous potential of quantum mechanics to build a  whole new generation of computers . While your brand new iMac might run like a dream, it basically works the same as computers that were built 80 years ago - a series of electrical circuits that switch on and off on command. The problem with our current computers is that we're close to hitting the limit for how advanced they can get, but the good news is  we now have all the building blocks  for a quantum computer, we just need to make it run. According to Microsoft's research lab, we could crack the quantum computing code within the next 10 years, so it's about time we understood exactly what that means, right?   The Verge has put togeth...

Tony Melov/UNSW Australian engineers just built a quantum logic gate in silicon for the first time We now have all the building blocks for a quantum computer. FIONA MACDONALD 6 OCT 2015       For decades, researchers have been trying to build a computer that harnesses the enormous potential of quantum mechanics. Now engineers from the University of New South Wales (UNSW)  in Australia have overcome the final hurdle, by creating a quantum logic gate in silicon - the same material that today's computer chips are made from. The newly developed device allows two quantum bits - or qubits - to communicate and perform calculations together, which is a crucial requirement for quantum computers. Even better, the researchers have also worked out how to scale the technology up to millions of qubits, which means they now have the ability to build the world's first quantum processor chip and, eventually, the first silicon-based qu...
