Replying to @DeltaDrift:Number of qubits is just one factor. Research quantum volume, logical qubits and algorithmic qubits. //@DeltaDrift:I get your point, but I think it’s still down to the number of Qubits that determines the computing power. And at current stage, all these computing power is used to enhance the quantum computer itself. As I’ve mention, IONQ is seeking for commercialize, while other two big corporation could risk creating something with a larger scale.//@fibance:$IONQ Inc.(IONQ)$$IBM(IBM)$ Not all qubits are created equal. Ionq uses ion trap technologies while IBM (and Google) uses superconducting qubits.
Superconducting qubits are faster but they produce a lot of errors because they are manufactured. They also require near 0-kelvin refrigeration to operate.
Ion traps on the other hand are slower but has higher fidelity and can operate at room temperature. The connectivity between qubits is all-to-all which means certain operations are simpler.
Comparing simply by quantity is like saying 100 bicycles is better than 1 Lambo
