Noun
quantum field (plural quantum fields)
(quantum mechanics) A quantum operator-valued function of (any point in) space.
The problem is that replacement of Quantum Mechanics by Quantum Field Theory is still very demanding. Martin Fleischmann
I wouldn't have thought that a wrong theory should lead us to understand better the ordinary quantum field theories or to have new insights about the quantum states of black holes. Edward Witten
Quantum field theory, which was born just fifty years ago from the marriage of quantum mechanics with relativity, is a beautiful but not very robust child. Steven Weinberg
What we live in, unfortunately, is a time when we are infected by what I call quantum field theory idolatry. Robert B. Laughlin
When I was at Berkeley, the framework of quantum field theory could calculate the dynamics of electromagnetism. It could roughly describe the motion of the weak nuclear force, radiation. But it hit a brick wall with the strong interaction, the binding force. David Gross
Ultimately, my Ph.D. is in mathematical physics, focusing on quantum field theory and curved space-time, and I worked with Stephen Hawking. Nathan Myhrvold
