Quantum Computing

Bottom Line

With multi-qubit programs, you’re finally in a position to introduce quantum effects that give new ways to solve your computational problems. The unique way in which qubelets of multiple qubits pair up with each other results in an exponential number of states that a quantum computer simultaneously deals with.

Although quantum computing affords you this unprecedented capability of juggling the equivalent of many states, getting them to perform a useful computational task is another matter. Representing gates as matrices and then matrix math gives you the means to work with all these states at once. But as the number of qubits increases, matrices become large and unwieldy and won’t provide the insight you need to design algorithms. ...
