Quantum Mechanics
-
Using extremely short, femtosecond pulses of light, engineers are working on ways to so finely control lasers that they can move electrons faster than electric currents – opening the way toward lightwave electronics.

Laser physicists have captured an atomic-level event – an electron being ejected from a helium atom after being struck by a photon – with an accuracy of a trillionth of a billionth of a second, showing the definitive correlation between quantum theory and experimental proof.

ScienceThe Nobel Prizes are being announced this month, and we now know the winners of the prizes in three fields of science: physics, chemistry and medicine. Here's what you need to know about the advancements in each area that led to the award of some of the world's most prestigious prizes.

We recently reported on a theory that says the Big Bang might have been prevented by the laws of quantum mechanics. As part of our "One Question" series, we asked theoretical physicist Steffen Gielen to help us understand more.

Scientists at the Kavli Institute of Nanoscience at the Delft University of Technology (TUDelft) have developed a memory technology that achieves the ultimate physical limit by using individual atoms to represent a single bit of data.

How the universe began is one of the most brain-breaking questions you could possibly ask. But what if the Big Bang was preceded by an earlier universe collapsing in on itself? A new study details how this might be possible.
-
Albert Einstein is famous for his theories on relativity, but what of his other grand hypothesis, the unified field theory that consumed the last 30 years of his life without resolution? So will a unified theory of everything ever be realized?
-
ScienceBy trapping photons inside a tiny gold cavity, scientists have created a hybrid state of light and matter. This could allow them to develop tiny on-chip lasers or tweak the chemical bonds of single molecules.

ScienceLight has long been one of the areas of physics that is best understood. But now researchers have discovered a new form of light that not only adds to our deeper understanding of its properties, but may help improve quantum computing and fiber-optic communications
-
Current quantum processors were once thought of as only precursors to creating future quantum computers, and too simple to do anything useful on their own. Now researchers have discovered a way to use them to solve very specific tasks much faster than normal computers can today

ScienceYou already know that water can have three states of matter: solid, liquid and gas. But scientists at the Oak Ridge National Lab (ORNL) have discovered that when it's put under extreme pressure in small spaces, the life-giving liquid can exhibit a strange fourth state known as tunneling.

A team of physicists have just created the world's smallest working engine from a single electrically-charged atom. With an equivalent efficiency (if scaled to size) of an average automobile engine, it actually produces a significant amount of power
