In a groundbreaking development in the field of quantum computing, researchers have successfully realized a logical magic state with fidelity beyond the distillation threshold on a superconducting quantum processor. The innovative protocol involves injecting the state to be prepared into one of the qubits in the surface code and then propagating the state information to the entire surface code, ultimately achieving a logical state preparation. According to Professor Zhu, who explained the protocol, the key to success lies in the strategic choice of the inject position of the state to be prepared and the initialization states of other qubits. This achievement represents a significant advancement in the quest for reliable and scalable quantum computers, with implications for a wide range of applications in science, technology, and beyond.
