There are multiple applications for quantum mechanics, such as quantum computing. It is also important for understanding chemistry, and many technologies operate at a level where quantum mechanics become important such as nanotechnology and teleportation. Quantum mechanics is a field that is actively researched and new discoveries are being made every day. It is widely considered as the future and culmination of all modern physics. It will, eventually, be applied to every aspect in life as we know it.
Now that you have a good understanding of quantum mechanics, you are ready to enter the world of quantum computing.
