IBM lays out quantum processor roadmap to 1kqubit
This close to the point where quantum systems can outperform classical computers at certain tasks. Conventional computers use bits to represent a 1 or 0 in digital logic but in a quantum computer a qubit can represent both a 1 and 0 at the same time and this allows for certain problems to be solved for large numbers of possible cases in a single pass.
This makes quantum computers very fast compared to classical computer but most quantum computers require temperatures close to absolute zero for the quantum mechanics to be practical for computation.
IBM plans to follow Eagle with the 433-qubit Osprey chip in 2022 and then with the 1,121-qubit Condor chip in 2023.
“We believe that we will be able to reach a demonstration of quantum advantage – something that can have practical value – within the next couple of years. That is our quest,” Darío Gil, a senior vice president at IBM and head of his research division, is quoted saying by Reuters.
