Kavli Affiliate: Wei Gao | First 5 Authors: Xianghao Zang, Ge Li, Wei Gao, , | Summary: In video surveillance, pedestrian retrieval (also called person re-identification) is a critical task. This task aims to retrieve the pedestrian of interest from non-overlapping cameras. Recently, transformer-based models have achieved significant progress for this task. However, these models […]
Kavli Affiliate: Mohammad Mirhosseini | First 5 Authors: Alkim Bozkurt, Chaitali Joshi, Mohammad Mirhosseini, , | Summary: Optomechanical crystals provide coupling between phonons and photons by confining them to commensurate wavelength-scale dimensions. We present a new concept for designing optomechanical crystals capable of achieving unprecedented coupling rates by confining optical and mechanical waves to deep […]
Kavli Affiliate: Austin J. Minnich | First 5 Authors: Peishi S. Cheng, Shi-Ning Sun, Alexander Y. Choi, Austin J. Minnich, | Summary: High-field charge transport in semiconductors is of fundamental interest and practical importance. While the ab initio treatment of low-field transport is well-developed, the treatment of high-field transport is much less so, particularly for […]
Kavli Affiliate: Rana X. Adhikari | First 5 Authors: Jonathan W. Richardson, Swadha Pandey, Edita Bytyqi, Tega Edo, Rana X. Adhikari | Summary: Squeezed light is critical in gravitational-wave detection for reaching sensitivities below the standard quantum limit. Achieving the quantum noise targets of third-generation detectors will require 10 dB of squeezing as well as […]
Kavli Affiliate: Alireza Marandi | First 5 Authors: Rajveer Nehra, Ryoto Sekine, Luis Ledezma, Qiushi Guo, Robert M. Gray | Summary: One of the most fundamental quantum states of light is squeezed vacuum, in which noise in one of the quadratures is less than the standard quantum noise limit. Significant progress has been made in […]
Kavli Affiliate: Rana X. Adhikari | First 5 Authors: Yehonathan Drori, Johannes Eichholz, Tega Edo, Hiro Yamamoto, Yutaro Enomoto | Summary: Optical losses degrade the sensitivity of laser interferometric instruments. They reduce the number of signal photons and introduce technical noise associated with diffuse light. In quantum-enhanced metrology, they break the entanglement between correlated photons. […]
Kavli Affiliate: Alireza Marandi | First 5 Authors: Gordon H. Y. Li, Ryoto Sekine, Rajveer Nehra, Robert M. Gray, Luis Ledezma | Summary: In recent years, the computational demands of deep learning applications have necessitated the introduction of energy-efficient hardware accelerators. Optical neural networks are a promising option; however, thus far they have been largely […]
Kavli Affiliate: Wei Gao | First 5 Authors: Yuyang Wu, Wei Gao, , , | Summary: As a fundamental data format representing spatial information, depth map is widely used in signal processing and computer vision fields. Massive amount of high precision depth maps are produced with the rapid development of equipment like laser scanner or […]
Kavli Affiliate: Austin J. Minnich | First 5 Authors: Adrian T. K. Tan, Shi-Ning Sun, Ruslan N. Tazhigulov, Garnet Kin-Lic Chan, Austin J. Minnich | Summary: The realization of novel phases of matter on quantum simulators is a topic of intense interest. Digital quantum computers offer a route to prepare topological phases with interactions that […]
Kavli Affiliate: Sunil Golwala | First 5 Authors: Shibo Shu, Andrew Beyer, Peter K. Day, Fabien Defrance, Jack Sayers | Summary: We present a multi-chroic kinetic inductance detector (KID) pixel design integrated with a broadband hierarchical phased-array antenna. Each low-frequency pixel consists of four high-frequency pixels. Four passbands are designed from 125 to 365 GHz […]
