| Abstract: | A quantum model of a real scalar field with local operator gauge symmetry is discussed. In the localized theory, in order
to keep the local operator gauge symmetry, an operator gauge potential BB
μ, is needed. By combining the constraint of operator gauge potentialB
μ, and the microscopic causality theorem, the usual canonical quantization condition of a real scalar field is obtained. Therefore,
a quantum model of a real scalar field without the usual procedure of quantizing a related classical model can be directly
constructed.
