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…
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…
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…
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…
Metalens array for complex-valued optical discrete Fourier transform
Randy Stefan Tanuwijaya, So Lap, Wai Chun Wong +3
Photonic computing has emerged as a promising platform for accelerating computational tasks with high degrees of parallelism, such as image processing and neural network. We presen…
