One thing that always amazes me is how much computational power it takes to simulate something as simple as a ball rolling through fur. Yet nature ‘just does it’—in an ‘instant’, whatever that meanspic.twitter.com/0ZUr1LWBn1

If you simulate one computer in another, the simulated one will always be significantly slower than the real one—particularly if you simulate it at the quantum level.

I'm not an expert here, but you'd probably want to be careful about what you consider to be 'equivalent resources' between the computer being simulated and the one doing the simulation

A simple example: for a Turing machine to move its read head from position x to position x+n takes O(n) steps, whereas other models of computation/actual computers have the ability to read any memory address in constant time, so when simulating a TM can potentially take shortcuts

It'll depend a bit on your definitions. A hypervisor gets closest to parity but it's debatable if that qualifies as a simulation. Exceeding parity would be like inventing a free energy perpetual motion machine.
