Investigating the reliable acoustic path properties in a global scale

open access: yesFrontiers in Marine Science, 2023
Leveraging the benefits of low transmission loss and high signal-to-noise ratio, the reliable acoustic path (RAP) has been extensively employed in various underwater applications. In this study, we investigate RAP properties on a global scale.

Loss-tolerant parity measurement for distant quantum bits [PDF]

open access: yes, 2016
We propose a scheme to measure the parity of two distant qubits, while ensuring that losses on the quantum channel between them does not destroy coherences within the parity subspaces. This capability enables deterministic preparation of highly entangled
