Quantum Correlations in Nonlocal BosonSampling

Understand

Determination of the quantum nature of correlations between two spatially separated systems plays a crucial role in quantum information science.

• Of particular interest is the questions of if and how these correlations enable quantum information protocols to be more powerful.
• Here, we report on a distributed quantum computation protocol in which the input and output quantum states are considered to be classically correlated in quantum informatics.
• Nevertheless, we show that the correlations between the outcomes of the measurements on the output state cannot be efficiently simulated using classical algorithms.
