IBM Promises 1000 qubit Quantum Computer

To what kinds of problems are likely to be addressed by Quantum computers?  Will this then be a narrowly focused 'supercomputer'.   HPC (High performance Computing) for specific problem types and domains. We worked with an early player in this space, and found the assignment still difficult to do.  How will this changed?   I like IBM's roadmap, gives us a process to push back on, which I look forward to examining. 

IBM promises 1000-qubit quantum computer—a milestone—by 2023
By Adrian Cho   in Science Mag

For 20 years scientists and engineers have been saying that “someday” they’ll build a full-fledged quantum computer able to perform useful calculations that would overwhelm any conventional supercomputer. But current machines contain just a few dozen quantum bits, or qubits, too few to do anything dazzling. Today, IBM made its aspirations more concrete by publicly announcing a “road map” for the development of its quantum computers, including the ambitious goal of building one containing 1000 qubits by 2023. IBM’s current largest quantum computer, revealed this month, contains 65 qubits.

“We’re very excited,” says Prineha Narang, co-founder and chief technology officer of Aliro Quantum, a startup that specializes in code that helps higher level software efficiently run on different quantum computers. “We didn’t know the specific milestones and numbers that they’ve announced,” she says. The plan includes building intermediate-size machines of 127 and 433 qubits in 2021 and 2022, respectively, and envisions following up with a million-qubit machine at some unspecified date. Dario Gil, IBM’s director of research, says he is confident his team can keep to the schedule. “A road map is more than a plan and a PowerPoint presentation,” he says. “It’s execution.” ... '
