Phase amplitude separation of wave function as local gauge transformation
A. R. P. Rau
A quantum-mechanical wave function is complex, but all observations are real, expressible through expectation values and transition matrix elements that involve the wave functions.…

1, 2, and 6 qubits, and the Ramanujan-Nagell theorem
Yaroslav Pavlyukh, A. R. P. Rau
A conjecture of Ramanujan that was later proved by Nagell is used to show on the basis of matching dimensions that only three -qubit systems, for , can share an isomo…
