Quantum superposition is also used as a tool in quantum computing and is the main reason quantum computers can be so powerful. A classical binary bit can only be in one state at a time: 0 or 1.

Quantum superposition is a phenomenon in which a tiny particle can be in two states at the same time — but only if it is not being directly observed.

Quantum superposition is the idea that particles exist in multiple states at once. When a measurement is performed, it is as if the particle selects one of the states in the superposition.

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

Quantum superposition is the idea that particles exist in multiple states at once. When a measurement is performed, it is as if the particle selects one of the states in the superposition.

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.

It’s the latest move in a broad effort to enable powerful quantum computers, which could transform everything from medicine ...

When talking about quantum physics, people will often nonchalantly say that particles can be in two places at once. Physicist Sabine Hossenfelder explores what is actually going on ...

The first principle, quantum superposition, enables minuscule particles to exist in many different states, or different versions of themselves, at once, until they are observed.
