IBM Condor paves the way toward quantum correction

IBM has unveiled Condor, a 1,121-qubit quantum processor that sets a new milestone in its roadmap. This system does not aim for raw speed, but rather to lay the groundwork for scaling quantum computing and, in the future, implementing error correction in a practical and efficient manner.

Qubit scaling and error correction 🧊

Condor uses an improved qubit coupling architecture and a cooling design that maintains quantum coherence on a large chip. IBM is betting on a modular approach, where the number of qubits is not the only factor; the fidelity of logic gates and the ability to interconnect multiple processors are equally relevant to achieving quantum advantage.

A thousand qubits and a cold coffee ☕

Having 1,121 qubits sounds impressive, but the reality is that most still behave like teenagers at a party: noisy and hard to control. IBM promises that over time they will learn to behave and correct their own errors. Meanwhile, we'll have to wait for the quantum coffee to be ready.
