SHFQC 8.5GHz 量子比特測控系統
- 2、4 或6 個控制輸出通道
- 1 個讀取輸入通道，可讀取分析多個qubits，qutrits 和ququads
- 工作頻率至8.5 GHz，瞬時頻寬1 GHz，無需混頻器校準（若需要> 8.5 GHz請聯繫我們）
- 低相位雜訊，低雜散，大輸出功率範圍，可滿足快速和高保真的閘門操作
- 即時訊號處理鏈路，具有匹配濾波器和多態鑑別功能
- 儀器內即可完成回授測控，延時350 ns
- 配套控制軟體LabOne ®，LabOne Q，和Python APIs
SHFQC 量子比特測控系統讀取多達 6 個超導量子位元並提供快速回饋。 它將 SHFQA 量子分析儀、SHFSG 訊號產生器等功能整合在一台儀器中。 憑藉整合微波產生、觸發和分配單元以及所有通道之間 350 ns 的超快回饋，SHFQC 和低溫恆溫器之間的簡單微波連接足以啟動高級量子位元測量。 為了為具有少量量子位元的系統提供靈活性，SHFQC 提供三種可能的配置，其中啟用 2、4 或 6 個訊號產生器通道。 對於 2 通道和 4 通道配置，可以在現場啟用額外的訊號產生器通道。 因此，該設定完全由軟體控制，並且可以根據需要重新配置以滿足實驗要求。
SHFQC 的每個控制通道都有自己強大的定序器，用於創建相位和定時可編程波形，因此單個SHFQC 可以用DC 至8.5 GHz 的脈衝控製或耦合量子位元，並隨時對讀出通道的測量結果做出反應。 透過 SHFQC-16W 升級選項，讀出通道的可自由配置積分權重和讀出脈衝記憶體從 8 個增加一倍至 16 個。這為配置讀出提供了更大的靈活性，例如： 透過實現 6 個量子點的完全即時控制和讀出。
