The race to build the first useful quantum computer is on and may revolutionize the world with brand new capabilities, from ...

His approach to quantum mechanics held unsettling implications about the meaning of death, and now he had nearly escaped its shadow. The Nazis had invaded his native Copenhagen in 1940.

In quantum mechanics, particles’ positions, velocities and other qualities are described by probabilities, not certainties. That means particles can be suspended in a weird purgatory known as a ...

There’s obviously some deep principle of quantum mechanics at play here, ... A very slightly better way to celebrate the ratio of a circle’s circumference to its diameter is July 22nd, ...

Quantum measurement. Quantum mechanics are the rules that govern the zoo of subatomic particles that make up the universe. Quantum mechanics tells us that we live in a fundamental nondeterministic ...

Quantum mechanics, or quantum physics, is the body of scientific laws that describe the wacky behavior of photons, electrons and the other subatomic particles that make up the universe.

In quantum mechanics, values such as position, momentum, energy and spin are "quantized," which means they can only take on certain discrete values rather than any value.

Quantum entanglement is a quantum mechanical phenomenon in which the quantum states of two or more objects have to be described with reference to each other, even though the individual objects may ...

In some ways, death doesn't exist in quantum mechanics. ... Then, in 1970, a small circle of physicists rediscovered it and coaxed Everett into elucidating his ideas.
