In this talk, we motivate the calculation of the matrix elements of novel CPviolating operators, the quark EDM and the quark chromo EDM operators, withinthe nucleon state using lattice QCD. These matrix elements, combined with thebound on the neutron EDM, would provide stringent constraints on beyond thestandard model physics, especially as the next generation of neutron EDMexperiments reduce the current bound. We then present our lattice strategy forthe calculation of these matrix elements, in particular we describe the use ofthe Schr\"odinger source method to reduce the calculation of the 4-point to3-point functions needed to evaluate the quark chromo EDM contribution. We endwith a status report on the quality of the signal obtained in the latticecalculations of the connected contributions to the quark chromo EDM operatorand the pseudoscalar operator it mixes with under renormalization.
