D-Wave Quantum's stock got crushed in November's tech sell-off.

Investopedia contributors come from a range of backgrounds, and over 25 years there have been thousands of expert writers and editors who have contributed. Doretha Clemons, Ph.D., MBA, PMP, has been a ...

Quantum technology is moving from lab curiosity to commercial reality, and the shift is starting to redraw the boundaries of ...

The light interacts with the cavity and makes an arbitrary number of bounces before leaking out. This emergent light is traditionally treated as heat in quantum simulations. However, it can still be ...

A new study suggests that gravity could quantum-entangle particles even if it remained classical.

For a future quantum internet to work, scientists need to perfect a quantum repeater that can send information over long ...

Quantum computing is a revolutionary form of computing that uses the principles of quantum mechanics to perform calculations that would be infeasible or impossible for classical computers. Unlike ...

I want to be clear about something right away. Many great companies have started by losing massive amounts of money, or have ...

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...

Quantum computers will be able to assume highly complex tasks in the future. With superconducting quantum processors, however ...

Researchers found that gold “super atoms” can behave like the atoms in top-tier quantum systems—only far easier to scale. These tiny clusters can be customized at the molecular level, offering a ...

The capability of qubits in a quantum computer to maintain their quantum mechanical state (their superposition state) over time. Otherwise, errors are generated. Maintaining this coherent state and ...
