Imagine trying to balance thousands of spinning tops at the same time—each top representing a qubit, the fundamental building block of a quantum computer. Now imagine these tops are so sensitive that even a slight breeze, a tiny vibration, or a quick peek to see if they’re still spinning could make them wobble or fall. That’s the challenge of quantum computing: Qubits are incredibly fragile, and even the process of controlling or measuring them introduces errors. This is where Quantum Error Corr...
