Abstract

Quantum information processors benefit from high clock frequencies to fully harness quantum advantages before they are lost to decoherence. All-optical systems offer unique benefits due to their inherent 100-THz carrier frequency, enabling the development of THz-clock frequency processors. However, the bandwidth of quantum light sources and measurement devices has been limited to the MHz range, with nonclassical state generation rates in the kHz range. In this study, we demonstrated broadband generation and quantum tomography of non-Gaussian states using an optical parametric amplifier (OPA) as a squeezed light source and an optical phase-sensitive amplifier (PSA). Our system includes a 6-THz squeezed-light source, a 6-THz PSA, and a 66-GHz homodyne detector. We successfully generated non-Gaussian states at a 0.9 MHz rate with sub-nanosecond wave packets using a continuous-wave laser. The performance is currently limited by the jitter of superconducting detectors, restricting the usable bandwidth to 1 GHz. Our technique extends the bandwidth to GHz, potentially increasing non-Gaussian state generation rates for practical optical quantum processors using OPAs.

摘要

量子信息处理器受益于高时钟频率，以便在退相干导致量子优势丧失之前充分利用这些优势。全光系统因其固有的100太赫兹载波频率而具有独特优势，这使得太赫兹时钟频率处理器的开发成为可能。然而，量子光源和测量设备的带宽一直限制在兆赫兹范围内，非经典态产生率在千赫兹范围内。在本研究中，我们使用光学参量放大器（OPA）作为压缩光源和光学相敏放大器（PSA），展示了非高斯态的宽带产生和量子层析成像。我们的系统包括一个6太赫兹的压缩光源、一个6太赫兹的PSA和一个66吉赫兹的零差探测器。我们使用连续波激光器成功地以0.9兆赫兹的速率产生了具有亚纳秒波包的非高斯态。目前，性能受超导探测器抖动的限制，将可用带宽限制在1吉赫兹。我们的技术将带宽扩展到吉赫兹，有可能提高使用OPA的实用光学量子处理器的非高斯态产生率。
