Intel's 49-Qubit Chip Shoots for Quantum Supremacy

IBM talks about a metric called "quantum volume" that combines number of qubits with error rate to summarise useful computing performance. See https://dal.objectstorage.open.softlayer.com/v1/AUTH_039c3bf...

(disclosure: IBMer, but very different area)

It is unknown if BQP >= NP or NP-complete

What makes one quantum computer superior to another? Not number of qubits, I guess? IBM has a 50-qubit machine.

Same as classical computers, what makes Intel i7 superior to AMD Ryzen 7?

One that can perform a computation task fastest with least energy would clearly be superior to another.

Is it vulnerable to meltdown?

Maybe if it was running real world applications with system and user space. Right now these all run prototype code
