By breaking away from the laws of classical physics, quantum physics has opened the door to describing the behavior of atoms and particles. This science, which explores the most fundamental building ...

In quantum computers, particles such as electrons or photons act as a qubit (quantum bit), which can be in a superposition of both 0 and 1. Three qubits can be in a superposition of all 8 possible ...

A new proposal makes the case that paraparticles—a new category of quantum particle—could be created in exotic materials.

With greater control over the quantum realm, physicists are poised to make major leaps in quantum computing, quantum gravity and more.

A team of physicists at Caltech have discovered a new way to use the natural motion of atoms to store and process quantum ...

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 physics keeps challenging our intuition. Researchers have shown that joint measurements can be carried out on distant particles, without the need to bring them together. This breakthrough ...

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. The second ...

A beam of quantum particles is shot at a pair of slits. The quantum properties of the matter allow each particle to be in a superposition of paths, passing through “both” slits at ...

For fans of science fiction, "quantum" is the go-to explanation for unbelievable phenomena, such as time travel or teleportation. Marvel took the practice to a new level in the 2023 film "Ant-Man ...
