混合量子阱上的量子门

Quantum gates on hybrid qudits

Jamil Daboul, Xiaoguang Wang, Barry C Sanders

摘要:

我们引入量子混合门,作用于不同维度的量子点。特别是,我们开发了两个代表性的两量子混合门(SUM和SWAP)和多量子混合Toffoli和Fredkin门。我们将混合SUM门应用于产生纠缠,发现对于一定的初态,SUM门的算符纠缠等于它所产生的纠缠。我们还证明了在一定条件下,对于两个不同维数的量子点,混合和门在泡利群上充当自同构。最后,我们描述了一个物理实现的自旋系统的混合门。

英文摘要:

We introduce quantum hybrid gates that act on qudits of different dimensions. In particular, we develop two representative two-qudit hybrid gates (SUM and SWAP) and many-qudit hybrid Toffoli and Fredkin gates. We apply the hybrid SUM gate to generating entanglement, and find that operator entanglement of the SUM gate is equal to the entanglement generated by it for certain initial states. We also show that the hybrid SUM gate acts as an automorphism on the Pauli group for two qudits of different dimension under certain conditions. Finally, we describe a physical realization of these hybrid gates for spin systems.
