Bell-State Quantum Holography with Metasurfaces
Qinmiao Chen, Guangzhou Geng, Hong Liang +5
Metasurfaces composed of subwavelength nanostructures enable simultaneous control of polarization and wavefront, greatly enhancing holographic information capacity. Building on thi…
Non-Markovian Exceptional Points by Interpolating Quantum Channels
Wai Chun Wong, Bei Zeng, Jensen Li
Exceptional points (EPs) are special points in non-Hermitian systems where both eigenvalues and eigenvectors coalesce. In open quantum systems, these points are typically analyzed…
Eigenmode-Guided Amplification via Spatiotemporal Active Acoustic Metamaterials
Wai Chun Wong, Greggory Chaplain, Jensen Li
We present a spatiotemporal gain-loss framework for eigenmode steering in coupled acoustic resonators. A cross-coupled gain-loss coefficient links the gain of one resonator to the…
Nonreciprocal Local-Resonance Induced Complex Band Hybridization
Wang Tat Yau, Kai Fung Lee, Raymond P. H. Wu +4
We study the complex band hybridization induced by nonreciprocal local resonances in photonic crystals. Composed of trimer unit cells, a two-dimensional (2D) magnetophotonic crysta…
Complete Interband Transitions for Non-Hermitian Spin-Orbit-Coupled Cold-Atom Systems
Dong Liu, Zejian Ren, Wai Chun Wong +5
Recently, synthetic spin-orbit coupling has been introduced into cold-atom systems for more flexible control of the Hamiltonian, which was further made time-varying through two-pho…
Metasurface for programmable quantum algorithms with quantum and classical light
Randy Stefan Tanuwijaya, Hong Liang, Jiawei Xi +3
Metasurfaces have recently opened up applications in the quantum regime, including quantum tomography and the generation of quantum entangled states. With their capability to store…
One-sided destructive quantum interference from an exceptional point-enabled metasurface
Hong Liang, Kai Ming Lau, Wai Chun Wong +3
We propose the concept of one-sided quantum interference based on non-Hermitian metasurfaces.By designing bianisotropic metasurfaces with a non-Hermitian exceptional point, we show…
Topological Theory for Perfect Metasurface Isolators
Wai Chun Wong, Wenyan Wang, Wang Tat Yau +1
We introduce topological theory of perfect isolation: perfect transmission from one side and total reflection from another side simultaneously. The theory provides an efficient app…
