Running wires from racks of electronics resembles the first electronic computers of the 1940s rather than the integrated circuit chips we have today.” It simply doesn’t scale as an approach to controlling thousands of qubits and beyond. “Controlling qubits in this way taps out around 50 or so qubits. “Each qubit needs to be controlled by a bunch of wires that typically run from racks of electronics at room temperature to the qubits at the end of a dilution refrigerator, at 0.01 degrees kelvin, close to absolute zero,” David Reilly, principal researcher and director of Microsoft Quantum Sydney, told Digital Trends. This is the cause of many errors in quantum computing, and results from the environment interacting with qubits in a way that changes their quantum states. This is important because one of the big challenges with quantum computers, which have the potential to change the face of computing as we know it, is something called qubit decoherence. Working with researchers from the University of Sydney in Australia, the Microsoft investigators say they have found a way to control thousands of qubits, the basic units of quantum information that are equivalent to binary bits in a classical computer, at extremely low temperatures. And, at least according to the Redmond, Washington-based company, it’s just made a notable advance in this domain.
#Microsoft win quantum error all windows#
Microsoft doesn’t just make Windows and Surface tablets - it’s also doing some pretty interesting work with quantum computers.
