IANS Faculty Adrian Sanabria breaks down what CISOs need to know about quantum computing and why it's not here to replace our everyday computers. Watch the full video here.
Instead, quantum computing should be thought of as a specialized tool, like a supercomputer designed for extremely difficult, specific tasks. Ordinary math or routine computing jobs aren’t its strong suit; instead, quantum computers answer questions where results are probabilistic, offering likelihoods between zero and one.
Despite all the hype around quantum computing right now, it isn't magic. While experts suggest we need one million qubits to break encryption, it is estimated that the biggest machines today have about 1,000 qubits. For now, the full promise of quantum computing remains unknown, but it is doubtful you will have a quantum computer in your pocket any time soon.
