There’s a surprising similarity between religions like Christianity, Hinduism, Buddhism, and modern science. They all suggest that the world we perceive might be rooted in something beyond our regular comprehension. This shared notion bridges the gap between spirituality and science, fueling our curiosity about external creators and the deeper layers of reality. The religious perspective ...
In 2020, scientists in Antarctica made an extraordinary discovery. At the center of their report were findings about particles that break the laws of physics. Some sources say these findings were “evidence” of a parallel universe. But can the parallel universes of Doctor Strange and Star Trek be a reality? Do we actually live in ...
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 ...
Future quantum computers are expected not only to solve particularly tricky computing tasks, but also to be connected to a network for the secure exchange of data. In principle, optical quantum gates could be used for these purposes. But until now, it has not been possible to realize them with sufficient efficiency. By a sophisticated ...
Systems in which mechanical motion is controlled at the level of individual quanta are emerging as a promising quantum-technology platform. New experimental work now establishes how the quantum properties of such quantum systems can be measured without destroying the quantum state — a key ingredient for tapping the full potential of mechanical quantum systems. When ...
At first glance, a system consisting of 51 ions may appear simple. But even if these charged atoms can only assume two different states, there will be more than two quadrillion (1015) different configurations the system can realize. This requires the use of quantum simulators. The behavior of such a system can therefore hardly be calculated with conventional ...
In physics, as in life, it’s always good to look at things from different perspectives. Such is the case with zero-index metamaterials. Since the beginning of quantum physics, how light moves and interacts with the matter around it has mostly been described and understood mathematically through the lens of its energy. In 1900, Max Planck used ...
Australian researchers have proven that near error-free quantum computing is possible, paving the way to build silicon-based quantum devices compatible with current semiconductor manufacturing technology. Professor Andrea Morello of UNSW, who led the work with partners in the US, Japan, Egypt, and at UTS and the University of Melbourne, said: “Today’s publication shows our operations ...
