Giuseppe Vallone, Enrico Pomarico, Francesco De Martini, Paolo Mataloni

摘要:

利用双光子4量子比特团簇态,我们在单量子比特旋转算法中实现了确定性单向量子计算。在该操作中,通过适当地选择量子比特的测量基来自动实现前馈测量,而泡利误差校正通过使用两个快速驱动的普克尔斯盒来实现。我们还实现了赤道量子位的C-NOT门和通用目标量子位的C-Phase门。我们的结果表明,双光子团簇态可以用于快速和有效的确定性单向量子计算。

英文摘要:

By using 2-photon 4-qubit cluster states we demonstrate deterministic one-way quantum computation in single qubit rotation algorithm. In this operation feed-forward measurements are automatically implemented by properly choosing the measurement basis of the qubits, while Pauli error corrections are realized by using two fast driven Pockels cells. We realized also a C-NOT gate for equatorial qubits and a C-Phase gate for a generic target qubit. Our results demonstrate that 2-photon cluster states can be used for rapid and efficient deterministic one-way quantum computing.
