Quantum > Phenomena and applications > Macroscopic quantum phenomena and applications
Quantum phenomena dominate the atomic and subatomic word, but several phenomena at the macroscopic scale reveal quantum behavior. The most outstanding examples are superfluidity and superconductivity. Quantum physics has several application in technology such as such as quantum computing, quantum sensing, quantum cryptography and quantum imaging.
Connection to Big Idea about particles: Many applications in our lives, like lasers, quantum computers, electronic microscopes, CDs, DVDs, MIR scans and many others are based in the quantum properties of microscopic particles. The photoelectric effect (according to which light can interact with matter) was the first phenomenon observed that demonstrated the macroscopic effects of quantum phenomena.
