Geometric phase and gauge theory structure in quantum computing
A. Bruno, A. Capolupo, S. Kak +2
We discuss the presence of a geometrical phase in the evolution of a qubit state and its gauge structure. The time evolution operator is found to be the free energy operator, rathe…

Gauge theory and two level systems
A. Bruno, A. Capolupo, S. Kak +2
We consider the time evolution of a two level system (a two level atom or a qubit) and show that it is characterized by a local (in time) gauge invariant evolution equation. The co…
