Negative pressure is a rare and challenging-to-detect phenomenon in physics. Using liquid-filled optical fibers and sound waves, researchers have now discovered a new method to measure it. In collaboration with the Leibniz Institute of Photonic […]
University of Maryland and IonQ Celebrate Opening of QLab: A Hub for Quantum Computing Research0 (0)
Insider Brief The University of Maryland (UMD) announced the grand opening of the National Quantum Laboratory (QLab). The research center was developed in partnership with IonQ. UMD has more than 200 quantum researchers, eight quantum-focused […]
Einstein’s theory of gravity—general relativity—has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure at spacetime singularities inside black holes—and the […]
In the future, quantum computers may be able to solve problems that are far too complex for today’s most powerful supercomputers. To realize this promise, quantum versions of error correction codes must be able to […]
A team of researchers led by Yumin Dong of Chongqing Normal University has developed a novel method to optimize parametric quantum circuits, a critical component of variational quantum algorithms. The method combines the power of […]
Insider Brief ParTec AG will invest five million euros in the construction of a production facility for assembly and testing of cryogenic and non-cryogenic systems. The company is positioning itself as a complete integrator of […]
Quantum 7, 1120 (2023). https://doi.org/10.22331/q-2023-09-25-1120 Symmetry is a unifying concept in physics. In quantum information and beyond, it is known that quantum states possessing symmetry are not useful for certain information-processing tasks. For example, states […]
Quantum 7, 1119 (2023). https://doi.org/10.22331/q-2023-09-25-1119 Quantum interference phenomena are widely viewed as posing a challenge to the classical worldview. Feynman even went so far as to proclaim that they are the $textit{only mystery}$ and the […]
Imagine an endless piece of blank paper covered with a smattering of lines pointing every which way. A gust of wind comes and sprinkles dust on top of the paper — in effect covering the […]
Quantum 7, 1118 (2023). https://doi.org/10.22331/q-2023-09-25-1118 Superconducting quantum circuits are a promising hardware platform for realizing a fault-tolerant quantum computer. Accelerating progress in this field of research demands general approaches and computational tools to analyze and […]
