What is quantum field theory Quora?

Quantum field theory is a theory that asserts particles are quantized wave excitations in fields that permeate the universe. The theory is the only logically consistent known way to put together quantum physics and special relativity.

Who introduced field theory?

Kurt Lewin

What is a quantum effect?

A quantum effect is any phenomenon which cannot be fully explained by classical mechanics — quantum mechanics is required. Quantum information science is based on any aspect of quantum effects which can be observed, measured, controlled, stored, or communicated in some manner.

What is quantum theory in simple terms?

Quantum theory is the theoretical basis of modern physics that explains the nature and behavior of matter and energy on the atomic and subatomic level. The nature and behavior of matter and energy at that level is sometimes referred to as quantum physics and quantum mechanics.

Is light a quantum particle?

Light is Quantized It isn't light as a particle. However, light is still pretty weird. There is a quantum nature to the electric and magnetic fields in light (quantum theory of radiation). But most of the stuff you look at can be explained using a classical wave model of light and a quantized model for matter.

What was Schrodinger's cat called?


What did Einstein think of quantum mechanics?

Einstein saw Quantum Theory as a means to describe Nature on an atomic level, but he doubted that it upheld "a useful basis for the whole of physics." He thought that describing reality required firm predictions followed by direct observations.
