我們提出了一種實驗上可實施之方法,藉由簡單地準備分離狀態作為測試輸入,然後對相應輸出的單個量子位進行簡單的局域測量,就可識別實驗過程中量子關聯性(包括EPR操控性和貝爾非定域性)的產生能力。這一發現可用於通用量子計算中,雙量子位元控制邏輯閘客觀之基準測試。
A method is introduced for identifying the creation of quantum correlations, including EPR steering and Bell nonlocality, for experimental processes, by simply preparing separable states as test inputs and then performing local measurements on single qubits of the corresponding outputs. This finding enables the construction of objective benchmarks for the two-qubit controlled operations used to perform universal quantum computation.
