For decades, the pursuit of quantum computing has struggled with the need for extremely low temperatures, mere fractions of a degree above absolute zero (0 Kelvin or –273.15°C). That’s because the quantum phenomena that grant quantum computers their unique computational abilities can only be harnessed by isolating them from the warmth of the familiar classical ...
In June, an IBM computing executive claimed quantum computers were entering the “utility” phase, in which high-tech experimental devices become useful. In September, Australia’s Chief Scientist Cathy Foley went so far as to declare “the dawn of the quantum era.” This week, Australian physicist Michelle Simmons won the nation’s top science award for her work ...
Quantum computers are becoming ever more complex and powerful. Researchers at the University of Innsbruck, in collaboration with the Johannes Kepler University Linz and the University of Technology Sydney, are now presenting a method to characterize even large quantum computers using only a single measurement setting. The gold standard for the characterization of quantum computers ...
Two milliseconds — or two-thousandths of a second — is an extraordinarily long time in quantum computing. On these timescales, the blink of an eye — at one 10th of a second — is like an eternity. Now a team of researchers at UNSW Sydney has broken new ground in proving that ‘spin qubits’ — ...
A roadmap for the future direction of quantum simulation has been set out in a paper co-authored at the University of Strathclyde. Quantum computers are hugely powerful devices with a capacity for speed and calculation which is well beyond the reach of classical, or binary, computing. Instead of a binary system of zeroes and ones, ...
Quantum computing, a field that relies on the principles of quantum mechanics to calculate outcomes, has the potential to perform tasks too complex for traditional computers and to do so at high speeds, making it in some ways the new frontier for science and engineering. Precise control of qubits — or quantum bits, the basic ...
Associate Professor Mazhar Ali and his research group at TU Delft have discovered one-way superconductivity without magnetic fields, something that was thought to be impossible ever since its discovery in 1911. The discovery, which was published in Nature, makes use of 2D quantum materials and paves the way toward superconducting computing. Superconductors can make electronics ...
A special form of light made using an ancient Namibian gemstone could be the key to new light-based quantum simulators, which could solve long-held scientific mysteries, according to new research led by the University of St. Andrews. The research, conducted in collaboration with scientists at Harvard University in the U.S., Macquarie University in Australia, and Aarhus ...
Quantum physical experiments exploring the motion of macroscopic or heavy bodies under gravitational forces require protection from any environmental noise and highly efficient sensing. An ideal system is a highly reflecting gravitational wave mirror whose motion is sensed by monochromatic light, which is photoelectrically detected with high quantum efficiency. A quantum optomechanical experiment is achieved ...
The way technology evolves is stunning to most people. In the computing realm, developments take place at an incredible rate, rendering prevalent technologies obsolete quickly. With time, computing devices continue to get smaller, yet their performance and capabilities get enhanced. Quantum computing is in a league of its own. Quantum computers are made to execute ...
