In recent years, quantum computers have captivated the world with their extraordinary potential. Industry giants like IBM and Google have been racing to build increasingly powerful quantum machines, with the expectation that they will revolutionize fields ranging from encryption to medical research. At the heart of these quantum machines are qubits, the quantum counterparts of classical bits, capable of existing in a superposition of both 1 and 0 simultaneously.
However, a significant stumbling block in the path of quantum computing progress is the phenomenon known as ‘quantum error.’ Even the most powerful quantum computers today suffer from inefficiencies, with more than 1,000 qubits affected by errors for every single unaffected ‘logical’ qubit.
