With quantum, this calculation could take about one minute. As an example, factoring a 2,048-bit prime number with today’s supercomputer takes about one trillion years. In addition, the new technology could make it possible to solve certain problems that have long been considered insoluble. Quantum computing would be able to solve these specific problems much faster than even the most powerful supercomputer of today. While classical computers are better adapted to everyday, simple processing, the new machines are well suited for complex tasks such as quantum simulations in molecular chemistry, optimization, and prime factorization. In quantum computing, power increases exponentially in proportion to the number of qubits with classical computing, power increases in a 1:1 relationship to the number of transistors. By contrast, classical computing calculates with transistors that represent either 0 or 1. The technology works by calculating with qubits, which can represent 0 and 1 at the same time. Quantum computing is a new technology that leverages the laws of quantum mechanics to produce exponentially higher performance for certain types of calculations, offering the possibility of major breakthroughs across several end markets.
