Full-Rank Noise Forbids Long-Range Entanglement Swapping
Xuan Du Trinh, Nicholas Pardave, Angie Huang +2
Quantum repeaters extend entanglement by swapping noisy elementary links. We prove that full-rank noise forbids this at long range: for any entangled full-rank two-qubit link, ther…
One Relative Phase Orders Operational Thresholds of Noisy Bell Pairs
Xuan Du Trinh
Unlike the two-qubit entangled and CHSH-nonlocal sets, the steerable and Bell-nonlocal ones have no known general closed-form criterion. For any such operational ability whose fail…
Operational thresholds of Bell mixtures with complex X noise
Xuan Du Trinh
Noisy Bell mixtures may carry entanglement, standard teleportation usefulness, projective-measurement steerability, and optimized Cavalcanti-Jones-Wiseman-Reid (CJWR) and Clauser-H…
Absorption capacity of separable noise: Bell-mixing thresholds on entanglement and teleportation
Xuan Du Trinh
We study Bell-mixing lines , where is a fixed Bell reference and is a separable two-qubit noise state. Along this line there are two operational crossin…
Adaptivity is not helpful for Pauli channel learning
Xuan Du Trinh, Nengkun Yu
We prove that adaptive strategies offer no advantage over non-adaptive ones for learning and testing Pauli channels using entangled inputs. This key observation allows us to charac…
