The computing power of quantum machines is currently still very low. Increasing performance is a major challenge. Â鶹ÒùÔºicists at the University of Innsbruck, Austria, now present a new architecture for a universal quantum ...
Quantum computers have attracted considerable interest of late for their potential to crack problems in a few hours where they might take the age of the universe (i.e., tens of billions of years) on the best supercomputers. ...
Quantum computers are powerful computational devices that rely on quantum mechanics, or the science of how particles like electrons and atoms interact with the world around them. These devices could potentially be used to ...
Molecules could make useful systems for quantum computers, but they must contain individually addressable, interacting quantum bit centers. In the journal Angewandte Chemie, a team of researchers has now presented a molecular ...
Researchers from Arizona State University and Zhejiang University in China, along with two theorists from the United Kingdom, have been able to demonstrate for the first time that large numbers of quantum bits, or qubits, ...
Quantum computers have the potential to outperform classical computers on several complex tasks, yet many challenges will need to be overcome before they reach their full potential. In the meantime, physicists and computer ...
In the 1950s, computers were bulky, inefficient and limited. They ate up entire rooms but couldn't go beyond rudimentary calculations.
Achieving scalability in quantum processors, sensors, and networks requires novel devices that are easily manipulated between two quantum states. A team led by researchers from the Department of Energy's Lawrence Berkeley ...
Two milliseconds—or two thousandths of a second—is an extraordinarily long time in the world of quantum computing. On these timescales the blink of an eye—at one 10th of a second—is like an eternity.
If you've ever tried to carry on a conversation in a noisy room, you'll be able to relate to the scientists and engineers trying to "hear" the signals from experimental quantum computing devices called qubits. These basic ...
