摘要:

由于量子位通常具有有限的寿命,因此其操作应该尽可能快,因此非绝热操作更优选。此外,由于量子比特不可避免地与周围环境相互作用,因此稳健的操作具有重要意义。在这里,我们提出了一个方案的极化激元量子比特的量子操纵电路QED使用非绝热完整性,这是固有的快速和鲁棒性。特别是,极化激元量子比特被证明是强大的,对任意的低频噪声,由于其近对称的频谱,这也可以方便地操纵外部微波驱动场在完整的方式。因此,我们的方案提出了一个很有前途的方式操纵极化激元量子位的片上固态量子计算。

英文摘要:

As a qubit usually has a limited lifetime, its manipulation should be as fast as possible, and thus non-adiabatic operation is more preferable. Moreover, as a qubit inevitably interacts with its surrounding environment, robust operations are of great significance. Here, we propose a scheme for quantum manipulation of the polariton qubit in circuit QED using non-adiabatic holonomy, which is inherently fast and robust. In particularly, the polariton qubit is shown to be robust against arbitrary low-frequency noise due to its near symmetric spectrum, which can also be convenient manipulated by external microwave driven fields in a holonomic way. Therefore, our scheme presents a promising way of manipulating polariton qubits for on-chip solid-state quantum computation.
