Title :
Numerical Study on Quantum Controllability
Abstract :
Quantum controllability refers to the possibility or difficulty of
a quantum process to be achieved. It includes how much energy or
control time is needed for a quantum transition induced by an
external field. Recently, we proposed a numerical approach
utilizing quantum optimal control theory (QOCT) to discuss
controllability problem. We found that controllability can be
graphically represented by two types of plots: the
probability-energy (P-E) plot and the energy-control time (E-T)
plot. These plots offer crucial information, including the
limitation of the shortest control time for a given fidelity. In
this talk, I will explain the basic idea of our method and
demonstrate the advantages of our approach with some illustrative
cases.
