As quantum computing develops, scientists are working to identify tasks for which quantum computers have a clear advantage over classical computers. So far, researchers have only pinpointed a handful of these problems, but in a new paper published in Physical Review Letters, scientists at Los Alamos National Laboratory have added one more problem to this

For the past six years, Los Alamos National Laboratory has led the world in trying to understand one of the most frustrating barriers that faces variational quantum computing: the barren plateau.Quantum Physics NewsRead More

Recent technological advances have opened new exciting possibilities for the development of cutting-edge quantum devices, including quantum random access memory (QRAM) systems. These are memory architectures specifically meant to be integrated inside quantum computers, which can simultaneously retrieve data from multiple ‘locations’ leveraging a quantum effect known as coherent superposition.Quantum Physics NewsRead More

Researchers have determined how to use magnons—collective vibrations of the magnetic spins of atoms—for next-generation information technologies, including quantum technologies with magnetic systems.Quantum Physics NewsRead More
