Which factors determine how fast a quantum computer can perform its calculations? Â鶹ÒùÔºicists at the University of Bonn and the Technion—Israel Institute of Technology have devised an elegant experiment to answer this question. ...
A Rice University-led study is forcing physicists to rethink superconductivity in uranium ditelluride, an A-list material in the worldwide race to create fault-tolerant quantum computers.
A Persian adage, notably wielded by Abe Lincoln and the band OK Go, expresses the ephemeral nature of the world: "This, too, shall pass."
High-precision measurements have provided important clues about processes that impair the efficiency of superconductors. Future work building on this research could offer improvements in a range of superconductor devices, ...
Scientists and journalists alike are disputing claims made by an international team of researchers that they had entangled a tardigrade with superconducting qubits. Their paper is published on the arXiv preprint server. Virtually ...
"Vacancy" is a sign you want to see when searching for a hotel room on a road trip. When it comes to quantum materials, vacancies are also something you want to see. Scientists create them by removing atoms in crystalline ...
Researchers at Lawrence Berkeley National Laboratory's Advanced Quantum Testbed (AQT) demonstrated that an experimental method known as randomized compiling (RC) can dramatically reduce error rates in quantum algorithms and ...
In 1973, physicist Philip W. Anderson theorized the existence of a new state of matter that has been a major focus of the field, especially in the race for quantum computers.
For quantum computers to surpass their classical counterparts in speed and capacity, their qubits—which are superconducting circuits that can exist in an infinite combination of binary states—need to be on the same wavelength. ...
There is a huge global effort to engineer a computer capable of harnessing the power of quantum physics to carry out computations of unprecedented complexity. While formidable technological obstacles still stand in the way ...
