quantum field

Noun

 * 1)  A quantum operator-valued function of (any point in) space.
 * 2) * ibid., &sect;7.3.1, page 190
 * The result is zero expectation value for &phi;, 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 &phi;. The field itself is unmeasurable.
