The standard interpretation of quantum mechanics places a lot of emphasis on the act of measurement. Before measurement, quantum systems exist in many states at once. After measurement, the system ...
Dark matter is an elusive form of matter that almost never emits, absorbs or reflects light, while only weakly interacting with regular matter. These properties make it very difficult to detect using ...

A German team just fully simulated a 50-qubit quantum computer for the first time — running it on Europe’s new exascale supercomputer, JUPITER
Researchers at the Jülich Supercomputing Centre in Germany have completed the first full simulation of a 50-qubit universal ...
One of the most perplexing aspects of quantum mechanics is that tiny subatomic particles don't seem to "choose" a state until an outside observer measures it. The act of measurement converts all the ...
More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...
One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...
When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that ...
Quantum mechanics is simultaneously beautiful and frustrating. Its explanatory power is unmatched. Armed with the machinery of quantum theory, we have unlocked the secrets of atomic power, divined the ...
What does quantum mechanics, the most successful theory ever proposed by physics, teach us about reality? The starting point for most philosophers of physics is that quantum mechanics must somehow ...
In July 1925, physicist Werner Heisenberg wrote a letter to Wolfgang Pauli sharing his new ideas about what would eventually become known as quantum theory. A hundred years later, that theory has been ...
In commemoration of the 100th anniversary of modern quantum mechanics, a survey asked physicists for their takes on some hot questions in quantum theory. Reading time 4 minutes In July 1925—exactly a ...
Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...
