Over the past few decades, significant progress has been made in quantum information
technology, from theoretical studies to experimental demonstrations. Revolutionary quantum …

The processing of information and computation is undergoing a paradigmatic shift since the
realization of the enormous potential of quantum features to perform these tasks. Coupled …

Generation of entanglement between spatially separated macroscopic systems enables
quantum networks and fundamental tests of quantum theory. Here, we propose a scheme to …

We propose a scheme to achieve nonreciprocal conventional photon blockades
simultaneously in two independent optical modes, which are connected by a two-level …

We study nonreciprocal single-photon scattering in a giant-spin-ensemble (GSE)–
waveguide magnonics system where the GSE constructed by a yttrium iron garnet sphere …

We propose a scheme for realizing strongly nonreciprocal double-carrier frequency combs
in three-mode cavity magnonic system consisting of two microwave cavities and a yttrium …

We study a single-photon band structure in a one-dimensional coupled-resonator optical
waveguide that chirally couples to an array of two-level quantum emitters (QEs). The chiral …

Unidirectional photon emission is crucial for constructing quantum networks and realizing
scalable quantum information processing. In the present work an efficient scheme is …

Chiral coupling at the single-quantum level promises to be a remarkable potential for
quantum information processing. Here we propose to achieve a chiral interaction between a …

We exploit controlled breaking of time-reversal symmetry to realize coherent routing of
quantum information in spin networks. The key component of our scheme is a spin triangle …
