论文摘要
我们提出了一个架构，以调查$ n $ Pather干涉仪中的波粒双重性在通用量子计算机上，该计算机涉及低至$ 2 \ log n $ Qubits，并制定了一种测量方案，该方案允许有效提取干扰可见性和哪个拨号信息的量词。我们为干涉仪实施算法，最多$ n = 16 $的原理实验路径在嘈杂的中间尺度量子（NISQ）设备上使用$ \ Mathcal {o}（o log n）$ gates且尽管增加了噪音始终如一地观察到互动的行为之间的互动性可视性和该图案信息。我们的结果符合我们当前对波颗粒对偶性的理解，并允许对干涉仪进行研究，该干涉仪在NISQ时代以外的未来量子设备上具有指数增长的路径数量。
We present an architecture to investigate wave-particle duality in $N$-path interferometers on a universal quantum computer involving as low as $2\log N$ qubits and develop a measurement scheme which allows the efficient extraction of quantifiers of interference visibility and which-path information. We implement our algorithms for interferometers with up to $N=16$ paths in proof-of-principle experiments on a noisy intermediate-scale quantum (NISQ) device using down to $\mathcal{O}(\log N)$ gates and despite increasing noise consistently observe a complementary behavior between interference visibility and which-path information. Our results are in accordance with our current understanding of wave-particle duality and allow its investigation for interferometers with an exponentially growing number of paths on future quantum devices beyond the NISQ era.
