A method, system, and computer program product for mapping a quantum circuit to a quantum processor. A light cone analysis is performed on the quantum circuit. A light cone refers to a map of the effects that the circuit operations have on the final observable value. Circuit operations that fall outside or within one or more light cones of non-identity operators in an observable based on the light cone analysis on the quantum circuit are then determined. The greater the number of overlapping or individual light cones that such circuit operations lie within, the greater the impact that such circuit operations have on the final observable value. A circuit mapping of the quantum circuit on the quantum processor is then determined based on the determination of which circuit operations fall outside or within the one or more light cones of non-identity operators in the observable.
