Entanglement buffering with two quantum memories

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Bethany Davies, Álvaro G. Iñesta, Stephanie Wehner, , | Summary: Quantum networks crucially rely on the availability of high-quality entangled pairs of qubits, known as entangled links, distributed across distant nodes. Maintaining the quality of these links is a challenging task due to the presence of time-dependent […]

Isotropic 3D topological phases with broken time reversal symmetry

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Helene Spring, Anton R. Akhmerov, Daniel Varjas, , | Summary: Axial vectors, such as current or magnetization, are commonly used order parameters in time-reversal symmetry breaking systems. These vectors also break isotropy in three dimensional systems, lowering the spatial symmetry. We demonstrate that it is possible […]
