There is much buzz around quantum computers because they are expected to surpass even the most powerful classic supercomputers in certain calculations — especially handling problems that involve sifting through massive amounts of data. Quantum computers, for example, might be able to find distant habitable planets, the cure for cancer and Alzheimer’s disease or revamp complex airline flight schedules.
Quantum machines offer a different kind of computing power because instead of relying on ones and zeros – or bits – they use qubits, which can be both ones and zeros.
One of the rules of quantum mechanics is that a quantum system can be in more than one state at the same time, meaning it’s not known what a qubit is until it begins to interact with — or entangle — other qubits. Unlike classic computers that operate in a linear or orderly fashion, quantum computers gain their power from qubits working with each other, allowing them to calculate all possibilities at the same time, instead of one by one.
