Query: Performance Analysis and Coherent Guaranteed Cost Control for Uncertain
  Quantum Systems Using Small Gain and Popov Methods   This paper extends applications of the quantum small gain and Popov methods
from existing results on robust stability to performance analysis results for a
class of uncertain quantum systems. This class of systems involves a nominal
linear quantum system and is subject to quadratic perturbations in the system
Hamiltonian. Based on these two methods, coherent guaranteed cost controllers
are designed for a given quantum system to achieve improved control
performance. An illustrative example also shows that the quantum Popov approach
can obtain less conservative results than the quantum small gain approach for
the same uncertain quantum system.
