Quantum computers should see rapid progress to millions of qubits

"Nobody is saying never anymore," says Scott Totzke, the chief executive of Isara Corp., a Canadian firm developing encryption resistant to quantum computers, which threaten to crack current methods. "We are in the very, very early days, but we are well past the science-fiction point."
Google, IBM and some other companies have been spending tens of millions of dollars per year on quantum computing projects for several years.
50-60 universal qubit quantum computers should be more powerful than any regular computer for a class of problems like optimization and code breaking.
The quantum computing systems that are currently in the performance lead are various types of superconducting based technology.
To keep costs lower these systems used older and cheaper lithography is about 200 nanometers. These are far from the leading edge of silicon lithography at 7 to 10 nanometers.
