The real trick to them is that they don't just use non-determination of states, but they can use interference. Grover's algorithm is a good example [1]. Check our this implementation [2]. There's a gate named F7 that will flip the 5th bit if the first four are the binary value 0111 (7). With those four input bits there are 16 possible input states... But using Grover's Algorithm it's able to correctly guess the required input to flip the 5th bit about 96% of the time. This is only using the F7 gate three times. If you double click on the F7 or the GROV gates at the top it'll show you their implementation.
