Physicists have created a novel type of analog quantum computer capable of addressing challenging physics problems that the most powerful digital supercomputers cannot solve. A groundbreaking study published in Nature Physics by a team of scientists from Stanford University in the United States a
in Ireland has revealed that a new type of highly specialized analog computer, equipped with quantum components in its circuits, can solve complex problems in quantum physics that were previously beyond reach. If these devices can be scaled up, they have the potential to provide insights into some of the most significant unresolved issues in physics.
Dr. Andrew Mitchell is the Director of the UCD Centre for Quantum Engineering, Science, and Technology , a theoretical physicist at the UCD School of Physics, and a co-author of the paper. He said: “Certain problems are simply too complex for even the fastest digital classical computers to solve.
The architecture for these new quantum devices involves hybrid metal-semiconductor components incorporated into a nanoelectronic circuit, devised by researchers at Stanford, UCD, and the Department of Energy’s SLAC National Accelerator Laboratory . Stanford’s Experimental Nanoscience Group, led by Professor David Goldhaber-Gordon, built and operated the device, while the theory and modeling were done by Dr. Mitchell at UCD.
Not to be sniffed at, analogous machines were used even into the late 20th century for mathematical calculations that were too hard for the most advanced digital computers at the time.
