In a step toward practical quantum computing, researchers from MIT, Google, and elsewhere have designed a system that can verify when quantum chips have accurately performed complex computations that classical computers can't.
Quantum chips perform computations using quantum bits, called "qubits,"...
Transistors based on germanium can perform calculations for future quantum computers. This discovery by the team of Menno Veldhorst is reported in Nature.
The development of quantum computing seems to be going very quickly. The building blocks for such a computer are so-called quantum bits. Over...
Beyond Earth's atmosphere are swirling clouds of energized particles—ions and electrons—that emanate from the sun. This "solar wind" buffets the magnetosphere, the magnetic force field that surrounds Earth.
In much the same way winds and storms create weather in our...
Astrophysicists have come a step closer to understanding the origin of a faint glow of gamma rays covering the night sky. They found that this light is brighter in regions that contain a lot of matter and dimmer where...
In the quantum realm, under some circumstances and with the right interference patterns, light can pass through opaque media.
This feature of light is more than a mathematical trick; optical quantum memory, optical storage and other systems that depend on interactions of...
A team of physicists has mapped how electron energies vary from region to region in a particular quantum state with unprecedented clarity. This understanding reveals an underlying mechanism by which electrons influence one another, termed quantum "hybridization," that had...
In everyday objects, there is no left without right or front without back. Just as inseparable seem to be the electron's electric charge and its "spin." But in a strictly one-dimensional quantum world, both quantum properties are separable from...
A team of researchers at Osaka University has investigated a new method for generating nuclear fusion power, showing that the relativistic effect of ultra-intense laser light improves upon current "fast ignition" methods in laser-fusion research to heat the fuel...
Classical physics is characterized by the precision of its equations describing the evolution of the world as determined by the initial conditions of the Big Bang—meaning there is no room for chance. Yet our day-to-day experience and intuition are...
Researchers have demonstrated a new all-optical technique for creating robust second-order nonlinear effects in materials that don't normally support them. Using a laser pulse fired at an array of gold triangles on a titanium dioxide (TiO2) slab, the researchers...
The most direct and strongest evidence for the accelerating universe with dark energy is provided by the distance measurements using type Ia supernovae (SN Ia) for the galaxies at high redshift. This result is based on the assumption that...
