    "abstract": "In a recent paper [Nieto M M 1996 Quantum and Semiclassical Optics, 8 1061;\nquant-ph/9605032], the one dimensional squeezed and harmonic oscillator\ntime-displacement operators were reordered in coordinate-momentum space. In\nthis paper, we give a general approach for reordering multi-dimensional\nexponential quadratic operator(EQO) in coordinate-momentum space. An explicit\ncomputational formula is provided and applied to the single mode and\ndouble-mode EQO through the squeezed operator and the time displacement\noperator of the harmonic oscillator.",
