Entanglement is at the heart of quantum information technologies which include quantum teleportation, quantum communication, quantum computation, and quantum sensing. In this talk, I introduce how entanglement is useful in the quantum information technologies. Then I keep an eye on the quantum sensing that aims at achieving high precision in obtaining information about a physical system using quantum states and measurements. One prominent example is the detection of a gravitational wave using the Michelson interferometer, which measures a tiny variation of path length in the interferometer signifying the existence of the gravitational wave.
