When measured, the qubit will collapse into 0 or 1 with a 50% propability. This is considered impossible for a traditional computer and has interetesting implications for cryptography, wheere random numbers known as "nonces" are important.Ī basic superposition can be accessed using the h gate. The superposition state is unstable, and once measured will collapse back into a discrete up or down state, but the probablity of doing so is dependent on the properties of the qubit's superposition at that time.Īn important point to note is that superposition results in true randomness where the probabilities can be controlled. The qubit can be manipulated to have a known probablity of ending up in the up or down state. Superposition is special because it allows for controlled randomness. These particles can also be put into a superposition - a special state where they are both up and down at the same time. Quantum computers use qubits - single atomic particles than can be in an "up" or "down" state - typically measured as 1 or 0. These transistors can either be on or off, typically represented as 1 or 0. Traditional computers store bits data using transistors. Quantum computers will touch Artificial intelligence, cryptography, phiysics and chemistry simulations, data organization, and more. Quantum computers enables radically new ways of solving problems with computers. The way they work is quite different, meaning they can solve problems that were complicated for traditional computers. Quantum computers will not replace traditional computers.
This is similar to how traditional computers were programmed in the 1950s. Today, quantum computers are programmed in the QASM language, an assembly-type language each qubit is manipuleted one line a time. Programming quantum computers is fundamentally different from programming classical computers.
