IBM promises 1000-qubit quantum computer—a milestone—by 2023. The problem in computer science is that this miniaturization is required for computers to process data. By itself, this is not a problem. To access QCS program-related publications, please visit Google Scholar. Many members of both groups seem to have assumed that sufficiently large quantum computers will be available soon. With the deluge of new information that must be catalogued and processed securely as well as the requirements that new scientific discoveries place on computers, the machines will soon reach their limits. As opposed to conventional binary computers, which operate in units of information represented by 1s or 0s, qubits can exist as a “1” and “0” at the same time.
