Could a particle accelerator using laser-driven implosion become a reality?

Could a particle accelerator using laser-driven implosion become a reality?

This is a schematic view of a bubble implosion, which is an envisioned picture showing the whole main events integrated, i.e., laser illumination, hot electron spread, implosion, and proton flash. Osaka University scientists discover new particle acceleration by micro-bubbles Laser pulse compression technology invented in the late 1980s developed high-power short-pulse laser techniques, enhancing laser […]

Lightning Inside This Ferocious Hurricane Blasted a Beam of Antimatter at Earth

When Hurricane Patricia shredded into the west coast of Mexico in October 2015, it was the strongest Pacific hurricane on record – but something else inside the swirling maelstrom also helped the violent storm make history. From inside the most intense tropical cyclone recorded in the Western Hemisphere, for the first time ever scientists observed a downward […]

Nuclear physicists leap into quantum computing with first simulations of atomic nucleus

Nuclear physicists leap into quantum computing with first simulations of atomic nucleus

Scientists at the Department of Energy’s Oak Ridge National Laboratory are the first to successfully simulate an atomic nucleus using a quantum computer. The results, published in Physical Review Letters, demonstrate the ability of quantum systems to compute nuclear physics problems and serve as a benchmark for future calculations. Quantum computing, in which computations are carried […]

Tunable diamond string may hold key to quantum memory

Electrodes stretch diamond strings to increase the frequency of atomic vibrations to which an electron is sensitive, just like tightening a guitar string increases the frequency or pitch of the string. The tension quiets a qubit‘s environment and improves memory from tens to several hundred nanoseconds, enough time to do many operations on a quantum […]

Stronger-than-binary correlations experimentally demonstrated for the first time

Stronger than binary correlations experimentally demonstrated for the first time

For the first time, physicists have experimentally demonstrated ternary—rather than binary—quantum correlations between entangled objects. The results show that the quantum measurement process cannot be described as a binary process (having two possible outcomes), but rather stronger-than-binary ternary measurements (which have three possible outcomes) should be considered in order to fully understand how the quantum […]

World Fastest Water Heater

Scientists Built The World’s Fastest Water Heater

  After about 70 femtoseconds (quadrillionths of a second) most water molecules have already split into hydrogen (white) and oxygen (red). Credit: Carl Caleman, DESY/Uppsala University Using X-ray Free-Electron Lasers, scientists have opened up way in structural biology, enabling imaging of biomolecules and dynamics that were impossible to access with conventional methods. They shoot extremely intense […]

Can a quantum drum vibrate and stand still at the same time?

Can a quantum drum vibrate and stand still at the same time?

  In quantum mechanics, objects can behave like both particles and waves. The objects can be here and there at the same time. Such counterintuitive behavior is typically confined to the microscopic realm and the question why don’t we see such behavior in everyday objects? Now, A team of researchers from the UK and Australia has developed a […]

Entangled atoms shine in unison

Entangled atoms shine in unison

Physicists compared the photon interference produced by entangled and non-entangled barium atoms. (Credit: IQOQI Innsbruck/Harald Ritsch) A team led by experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for […]
