Is a wave function as complete as can be

Click For Summary
SUMMARY

A wave function in standard quantum mechanics fully describes the state of an isolated system in one dimension, with no hidden variables or additional information required. The completeness of the wave function is a fundamental principle, ensuring that all relevant aspects, such as spin, are encompassed within the quantum state. This discussion confirms that the wave function is sufficient for a comprehensive understanding of the system's behavior.

For a wave function describing the state of an isolated system in 1D, does a wave function describe a system completely?
 
Physics news on Phys.org
According to standard quantum mechanics the quantum state represented by a wave function is complete. The are no further hidden variables or hidden information.

Of course one has to take into account relevant information like spin etc.
 
Ooh! Not got up to spin, yet.
Thank you.
