Like other aspects of quantum science, the phenomenon of entanglement reveals itself at very tiny, subatomic scales. When two particles, such as a pair of photons or electrons, become …

"To have a truly usable system, you may need to combine quantum cryptography with elements that are not quantum, and those other elements could be vulnerable to attacks that theorists …

Entanglement: This is a phenomenon that occurs when two or more objects are connected in such a way that they can be thought of as a single system, even if they are very far apart.

Caltech experts explain the science behind quantum computing in simple terms and outline what quantum computers could be used for.

Caltech researchers explain how they design experiments using specialized tools and techniques to probe the elusive phenomena of quantum mechanics.

Waves would spread outward from each point, eventually overlapping to form a more complex pattern. This is a superposition of waves. Similarly, in quantum science, objects such as …

While some applications of quantum physics may seem far off, quantum principles are already at work in many technologies available today. For example, a common kitchen appliance …

How Are Quantum Phenomena Used in Technology Today? Surprising but true: Quantum mechanics are at work inside of your toaster and other devices we encounter in everyday life. …

Paul Wennberg discusses the air quality following the 2025 California fires and how to clean homes downwind of the fires.
