Current situation of quantum computing with respect to physical vs logical qubits
As an example I'm going to start with Google and IBM. Google has the Sycamore processor right now with 53 physical qubits. However I haven't found any info on how many logical qubits it can actually ...

Sycamore 2 versus Osprey
Google recently hit key milestone by reducing errors: https://www.nature.com/articles/d41586-023-00536-w
I would like to know why Google's QPU had way fewer qubits than IBM's Osprey and if IBM also ...

Does a quantum computer exist today? [closed]
I agree that this may not be an easy question to answer.
But lately, I increasingly come across the fact that many news materials and research papers in the field of quantum technologies say that at ...

How are the IBM's and Google's Hadamard gates fabricated and operated?
There are thousands of articles, books and web sites describing the Hadamard Gate from a theoretical point of view.
But I haven't been able to find any photo about any real implementeation of a ...

Why does Google's quantum processor outperform IBM's?
I understand that both have 53 qubit devices, yet it is Google that has demonstrated quantum supremacy (although IBM refutes this!). I'm not sure if this is true but it seems like IBM cannot replicate ...

Why do the IBM and Google processors both have 53 qubits?
As I understand from this IBM post both the IBM and Google teams have independently built 53-qubit processors. What is the significance of the number 53? It is purely coincidental, or is there a ...
