A ball tossed into the air follows a path that classical physics can track with confidence. Shrink that ball down to the size ...

In quantum mechanics, particles do not behave like everyday objects. Instead of existing in one clearly defined state, they ...

A new study by researchers at the Massachusetts Institute of Technology (MIT) now bridges ...

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 ...

The universe looks like it is mostly empty space. Remove the stars, planets, dust, and gas, and what remains is nothing at ...

Typically, adding energy to a system makes it hotter. But last year, scientists demonstrated that quantum systems don’t ...

A pair of identical particles swapping places sounds like a small move. In quantum physics, it is a defining one. In everyday three-dimensional space, that swap only comes in two flavors. Either the ...

Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The ...

As long as there's been an internet, there's been a way to hack it. Scientists have spent decades imagining a different kind ...

DENVER — An urgent call comes in from the White House. But the recipient is skeptical: They need a way to verify that the message comes from the purported location. Quantum physics has a solution.

Penn engineers have taken quantum networking from the lab to Verizon’s live fiber network, using a silicon “Q-chip” that speaks the same Internet Protocol as the modern web. The system pairs classical ...
