Quantum Computers Do the (Instantaneous) Twist
Regardless of what makes up the innards of a quantum computer, its speedy calculations all boil down to sequences of simple instructions applied to qubits—the basic units of information inside a quantum computer.
New Protocol Helps Classify Topological Matter
Topological materials have captured the interest of many scientists and may provide the basis for a new era in materials development. On April 10, 2020 in the journal Science Advances, physicists working with Andreas Elben, Jinlong Yu, Peter Zoller and Benoit Vermersch, including JQI Fellow Mohammad Hafezi and former JQI postdoctoral researcher Guanyu Zhu (currently a research staff member at IBM T. J.
Donuts, Donut Holes and Topological Superconductors
Topology—the mathematical study of shapes that describes how a donut differs from a donut hole—has turned out to be remarkably relevant to understanding our physical world. For decades, it’s captured the hearts and minds of physicists, who have spent that time uncovering just how deep the connection between topology and physics runs. Among many other things, they’ve unearthed a prediction, born of topology, for a new particle with promising applications to quantum computing.
Ring resonators corner light
Researchers at the Joint Quantum Institute (JQI) have created the first silicon chip that can reliably constrain light to its four corners. The effect, which arises from interfering optical pathways, isn't altered by small defects during fabrication and could eventually enable the creation of robust sources of quantum light.
Latest nanowire experiment boosts confidence in Majorana sighting
In the latest experiment of its kind, researchers have captured the most compelling evidence to date that unusual particles lurk inside a special kind of superconductor. The result, which confirms theoretical predictions first made nearly a decade ago at the Joint Quantum Institute (JQI) and the University of Maryland (UMD), will be published in the April 5 issue of Nature.
