Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a ...

With the help of a new experiment, researchers have succeeded in confirming a ten-year-old theoretical study, which connects one of the most fundamental aspects of quantum mechanics -- the ...

Quantum computers, systems that process information leveraging quantum mechanical effects, have the potential of ...

Advances in recent years suggest we are entering the Quantum Frontier Era. National security, science, economic competitiveness, and cybersecurity will all feel the impact.

Quantum entanglement is a state in which particles are entwined with each other. In this entwined state, the properties of one particle influence the other, even when they aren't physically close to ...

A team at the University of Chicago has discovered a surprisingly simple way to create powerful quantum states that are normally difficult to produce. By making small adjustments to the energy levels ...

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 ...

Scientists have peered inside protons and discovered that quarks and gluons, their fundamental building blocks, experience quantum entanglement. Entangled particles are connected to each other, so ...

Faster-than-light particles have spent decades in physics as both temptation and warning. They offered a way to test the ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...
