The local emulator simulates quantum hardware noise by constructing a noise model from calibration data, applying depolarizing noise to each gate, applying readout error at the end, and using a local density matrix simulator.
The local device emulator can be instantiated from a quantum device or a set of device properties.
The local emulator uses device calibration data to validate verbatim circuits and help catch compatibility issues earlier.
The blog says the local device emulator accelerates quantum software development with verbatim circuits.
