Quantum computers, computing systems that process information using quantum mechanical effects, could outperform classical computers on some computational tasks. These computers rely on qubits, the basic units of quantum information, which can exist in multiple […]
Physicists have directly visualized the fundamental electronic building blocks of flat-band quantum materials, a class of systems in which electron motion is effectively quenched and strong interactions give rise to emergent phases of matter. In […]
In new research published in Physical Review X, scientists have designed quantum control protocols that generate processes more consistent with time flowing backward than forward. The protocols—techniques to control quantum systems—modify a quantum system’s “arrow […]
Over the past decades, quantum scientists have introduced various technologies that operate leveraging quantum mechanical effects, including quantum sensors, computers and memory devices. Most of these technologies leverage entanglement, a quantum phenomenon via which two […]
Quantum computers could solve certain problems that would take traditional classical computers an impractically long time to solve. At the Japan Advanced Institute of Science and Technology (JAIST), researchers are now working to make these […]
You’re late for an important appointment. Just as you are leaving your house, you realize your phone is flat. Imagine you could charge it almost instantly by exploiting the strange rules of quantum physics. That’s […]
Quantum communication systems are emerging solutions to transmit information between devices in a network leveraging quantum mechanical phenomena, such as entanglement. Entanglement is a quantum effect that entails a link between two or more particles […]
Australian scientists have made a significant leap forward in energy storage technology with the world’s first proof-of-concept quantum battery. Similar to conventional batteries, this quantum version charges, stores and discharges energy—and is the first to […]
A new laser range-finding technique, inspired by quantum physics, that can measure distances under strong solar background has been demonstrated by researchers at the University of Bristol. The team has proved their hypothesis by testing […]
