Just as electrons flow through an electrical conductor, magnetic excitations can travel through certain materials. Such excitations, known in physics as “magnons” in analogy to the electron, could transport information much more easily than electrical […]
Qubits, the building blocks of quantum computers, can be made from many different technologies. One way to make a qubit is to trap a single neutral atom in place using a focused laser, a technique […]
A new review paper on magnetic topological materials introduces a theoretical concept that interweaves magnetism and topology. It identifies and surveys potential new magnetic topological materials and suggests possible future applications in spin and quantum […]
A nuclear reactor at an Illinois energy plant is helping University of Chicago scientists learn how to catch and understand the tiny, elusive particles known as neutrinos. Click to rate this post! [Total: 0 Average: […]
Physicists at UC Santa Barbara have become the first to experimentally observe a quirky behavior of the quantum world: a “quantum boomerang” effect that occurs when particles in a disordered system are kicked out of […]
In a new study, Stanford researchers demonstrate how to manipulate atoms so they interact with an unprecedented degree of control. Using precisely delivered light and magnetic fields, the researchers programmed a straight line of atoms […]
A quantum processor working with photons developed at the University of Twente becomes an ever stronger ‘toolbox’ for doing experiments. The latest version not only has more inputs and outputs, it can also be fed […]
Quantum theory was originally formulated using complex numbers. Nonetheless, when replying to a letter by Hendrik Lorenz, Erwin Schrödinger (one of its founding fathers), wrote: “Using complex numbers in quantum theory is unpleasant and should […]
The Advanced Quantum Testbed (AQT) at Lawrence Berkeley National Laboratory (Berkeley Lab) has open sourced a new electronics control and measurement system for superconducting quantum processors, making the engineering solutions for the emerging hardware more […]
The field of machine learning on quantum computers got a boost from new research removing a potential roadblock to the practical implementation of quantum neural networks. While theorists had previously believed an exponentially large training […]
