利用最少数量的量子发射器产生光子源态

Photonic resource state generation from a minimal number of quantum emitters

Bikun Li, Sophia E. Economou, Edwin Barnes

摘要:

多光子纠缠图态是量子通信网络、分布式量子计算和传感中的基本资源。这些状态原则上可以从量子发射器确定性地创建,例如光学活性量子点或缺陷,原子系统或超导量子位。然而,寻找产生这种状态的有效方案一直是一个长期的挑战。在这里,我们提出了一个算法,给定一个所需的多光子图形状态,确定量子发射器的最小数量和精确的操作序列,可以产生它。算法本身和由此产生的操作序列都在光子图形状态的大小多项式缩放,允许一个获得有效的计划,以产生包含数百或数千个光子的图形状态。

英文摘要:

Multi-photon entangled graph states are a fundamental resource in quantum communication networks, distributed quantum computing, and sensing. These states can in principle be created deterministically from quantum emitters such as optically active quantum dots or defects, atomic systems, or superconducting qubits. However, finding efficient schemes to produce such states has been a long-standing challenge. Here, we present an algorithm that, given a desired multi-photon graph state, determines the minimum number of quantum emitters and precise operation sequences that can produce it. The algorithm itself and the resulting operation sequence both scale polynomially in the size of the photonic graph state, allowing one to obtain efficient schemes to generate graph states containing hundreds or thousands of photons.
