IBM Hits Quantum Volume of 64 in Deployed System

How useful is this for real problems in context?  Looking for some write up on that and will report here.  Statement of volume metric below is useful.   Note this is a 6 Cubit system.

IBM hits new quantum computing milestone
The company has achieved a Quantum Volume of 64 in one of its client-deployed systems, putting it on par with a Honeywell quantum computer.

' .... IBM on Thursday announced it's reached a new quantum computing milestone, hitting its highest Quantum Volume to date. Using a 27-qubit client-deployed system, IBM achieved a Quantum Volume of 64. 

Quantum Volume is a metric that determines how powerful a quantum computer is. It measures the length and complexity of quantum circuits, the building blocks of quantum applications. Just two months ago, Honeywell similarly announced it had a quantum computer running client jobs with a Quantum Volume of 64. Honeywell reached the milestone with just a 6-qubit system. 

IBM's previous Quantum Volume milestone, announced in January, was 32. The company said it reached a Quantum Volume of 64 through a series of new software and hardware techniques applied to a system already deployed within the IBM Q Network, a network of developers and industry professionals designed to collectively advance quantum computing.  ...
