The Deep Underground Neutrino Experiment aims at an unprecedentedly precise neutrino CP
violation phase measurement with a broad-band muon neutrino and antineutrino beam, a 1,300 km baseline, an order of 10s
kt fiducial mass detector with high particle identification efficiency and low external background.
Additionally, the orders of systematic uncertainty should be constrained to 2% for the signal and
5% for the background. This uncertainty constraint requires an unprecedented level of robustness
and redundancy in the near detector measurement. In this presentation, the near detector design
and the far detector prototyping status are shown. The long-baseline sensitivity and different
physics potentials are described.
