Quantum state space
Quantum state space - Wikipedia
A quantum state space is an abstract space in which different positions represent, not literal locations, but rather quantum states of some physical system.
In quantum physics, a quantum state is a mathematical entity that embodies the knowledge of a quantum system. Quantum mechanics specifies the construction, ...
What is the 'state space' of a quantum field theory called?
