Estimating the coupling strength of a Hamiltonian with four different measurement strategies

2020 · Modern Physics Letters A

In this paper, we compare different measurement strategies for estimating coupling strength of a Hamiltonian. In particular, we estimate the coupling strength coefficient when the Hamiltonian couples the pointer (measuring device) momentum to an observable …

Selectively steering photon spin angular momentum via electron-induced optical spin Hall effect

2021 · Science Advances

The development of the optical spin Hall effect (OSHE) realizes the splitting of different spin components, contributing to the manipulation of photon spin angular momentum that acts as the information carrier for quantum technology. However, …
