Quantum Coherence and Quantum Interference: is there any distinction in the quantum realm as well?

Coherences modify the dynamics of quantum systems by coupling with populations. For example, Electromagnetically induced transparency, coherent population trapping. One physical explanation for...

Does any general relationship exist for Fermionic Creation/Annihilation Operators?

For Boson creation and annihilation operators, b|n>=\sqrt{n}|n-1> and b^\dag=\sqrt{n+1}|n+1>, in the Fock space. I know for Fermion systems, n=1,0. However, does any general relationship exist...
