Quantum Supremacy Milestone?
Rumours abound that Google's quantum processor Sycamore has performed a task that would flummox the best classical computer — a first in quantum computing. Physicist Ian Durham assesses the claims, gives us a quantum computing primer, and discusses concerns about the term 'quantum supremacy'.

Happy Christmas Jason.

Thank you for considering my posts. I see I will not persuade you around to my way of thinking. We are both attached to our own models. I think if you are going to talk about making time it would be good if you qualified that by explaining the kind of time you are referring to. I think you mean the time component of space-time, but as I have said 'tine' has many different meanings.

How prescient, Loraine.

Your last post on the 23rd is like a mirror of the future in the announcement on the 24th of this years topic in the FQXI Essay contest. How can we have an 'overview'? Can't we?.

Perhaps what emerges into the intuitive experience of the macro world is not the grand sum of properties in actions of the micro...
