Quantum Class refers to a category of particles in quantum physics that includes fundamental particles like quarks and leptons. These particles are the building blocks of matter and exhibit unique behaviors that differ from classical physics, such as being able to exist in multiple states at once, a phenomenon known as superposition. In addition to their unique properties, particles in the Quantum Class are also subject to quantum entanglement, where the state of one particle can instantaneously affect another, regardless of distance. This interconnectedness is a key feature of quantum mechanics and has implications for technologies like quantum computing and quantum cryptography.
