Abstract
The optimum detection operators are derived for several linearly indep endent signal sets. The quantum minimax strategy is applied to the M-a ry coherent state signals such as binary phase shift, ternary symmetri c, ternary phase shift, and quadrature phase shift. It is shown that t he detection process induces a kind of quantum interference between si gnal quantum states and measurement states.
