What matters more than the number of qubitsIn discussions about quantum computers, we tend to focus on the number of qubits.

Einstein's theory of general relativity describes gravity as the bending of spacetime, a mathematical model that combines ...

Electrons inside a diamond have given a floating, centimeter-sized device a quantum nudge, opening a new path toward testing ...

Oxford physicists have recreated a bizarre quantum effect in which a particle responds to a magnetic field without ever traveling through it. Using a hybrid quantum computer, they demonstrated how ...

A concept from the field of quantum mechanics, spin is a property of particles that has no direct counterpart in everyday ...

Researchers at Friedrich Schiller University Jena and the University of Regensburg have developed a method for determining, ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to Albert Einstein’s instincts about reality. By stripping classic thought ...

As strange and unique as the laws of the quantum realm appear in our everyday experience, every now and then experiments catch sight of phenomena that seem both alien and yet eerily familiar. For the ...

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity. Now a new theoretical study pushes that weirdness into even stranger territory. It ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

Measuring gravitational analogues of quantum phenomena could lead to high-precision measurement of gravitational forces, according to a theoretical proposal. Micromuffins. The 1-µm-wide ...
