Physicists construct theories to describe nature. Let us explain it through an analogy with something that we can do in our everyday life, like going on a hike in the mountains. To avoid getting lost, ...

By adapting ideas from gauge theory, the researchers show how quantum information spread-out across a machine can be measured using only local checks, significantly lowering computing overhead. Their ...

Scientists have always wondered whether ordinary materials are also secretly held together by quantum ...

Dr. Dominic Williamson, a University of Sydney quantum physicist, has developed a new approach to quantum error correction that could significantly reduce the number of physical qubits required to ...

The square root of a negative number could easily be regarded as a curious mathematical construction that has little bearing on real life. Indeed, the French polymath René Descartes gave such numbers ...

Research findings are available online in the journal Science Advances. The original story “ Physicists use pulses of light ...

Other scientists have investigated the idea of a hidden structure further. David Bohm, a 20th-century physicist, built a ...

Physicists have proposed a way to extract the internal quantum states of electron wave packets by analyzing how those packets ...

A Gravity Theory That Could Rewrite the Universe’s First Moments The first fraction of a second after the Big Bang has always ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Several years ago one of us, Toni, asked another of us, Marco, to come to his office at the Institute of Photonic Sciences, a large research center in Castelldefels near Barcelona. “There is a problem ...
