Recently, I started to learn quantum engineering, quantum computer will become maintstream in IT development by 2023 because its performance exponentially faster than current computer. Currently it is using in field of on encryption, protein folding simulated, new medicine and treatments, etc. Its programming technique is very different from current one, I just finished a certification of Quantum Computing & Quantum Physics course, which taught about Quantum Cryptography, and Quantum Physics with Microsoft Q# (Q Sharp) & IBM Quantum Experience.
How fast are Quantum Computers? A 64-bit quantum computer can process 36 billion billion bytes of information in each step of computation, it is too too fast to compare that to the 8 bytes that your home computer can process in each step of computation!
