I am new to the Quantum Computer world. I understand the basics of Quantum mechanics and I have watched a few lectures on Quantum computers, Quantum gates and played a bit on IBM QC.
As far as I understand every qubit and every QC will output a probabilistic value. For example 1+1 could be
How can we do a deterministic simple computation like 1+1=2 via a quantum computer? and if we can, how can it be faster than a classical computer?
