The field of quantum computing is advancing relentlessly: equipped with a performance that far exceeds that of our conventional PCs, the high-tech computers of the future will solve highly complex problems that have so far defeated even the largest supercomputers. And indeed, Chinese researchers have now made another breakthrough in the digital world of qubits – and with the Zuchongzhi 3.0, they have presented a quantum computer that even rivals Google’s Willow! But what can the new high-tech computer do? How does a quantum computer work anyway? And above all, how will the high-performance computers change our everyday lives?
