Quantum computing is a field of study and technology that leverages the principles of quantum mechanics to perform complex computations. It utilizes quantum bits or qubits, which can exist in multiple states simultaneously, allowing for exponential processing power and the potential to solve problems that are currently intractable for classical computers. Though much of quantum computing is confined to the laboratory, quantum computers have the potential to surpass classical computers and lead to a pivotal technological disruption.
IBM built a 433 quantum bit (or qubit) computer last year. For its 10 year plan, the company is setting its sights on building a 100,000-qubit computer to facilitate breakthroughs in drug discovery, fertilizer and battery performance.
