quantum field

== English == === Noun === quantum field (plural quantum fields) (quantum mechanics) A quantum operator-valued function of (any point in) space. ibid., §7.3.1, page 190 The result is zero expectation value for φ, and this would be true for whatever state, including the vacuum, that we choose. This effectively means that we would measure nothing if we tried to measure the quantum field φ. The field itself is unmeasurable. ==== Synonyms ==== operator field ==== Derived terms ==== quantum field theory ==== Translations ==== ==== References ==== Robert D.
