A quantum field is a theoretical concept that describes how subatomic particles behave and interact in accordance with quantum mechanics and relativity. quantum fields are associated with different types of particles, such as electrons, photons, quarks, and gluons. Each quantum field pervades the entire universe and has a value at every point in space and time. The value of a quantum field represents the probability of finding a particle of that type at that point. Particles can be seen as excitations or disturbances of their underlying quantum fields.
