In a new report now published on Science Advances, Tiancheng Song and a research team at the department of physics, University of Washington, U.S., and materials and nanoarchitectronics in Japan and China, detailed spin photovoltaic […]
Similar to a magnet that always has both south and north poles, a kind of special quasiparticles in condensed matter called “Weyl Fermions” always appear in pairs with opposite chirality. There had been no experimental […]
Scientists have generated circularly polarized light and controlled its direction without using clunky magnets or very low temperatures. The findings, by Nagoya University researchers and colleagues in Japan, and published in the journal Advanced Materials, […]
Imagine you’re a general in ancient times and you want to keep your troop counts secret from your enemies. But you also need to know this information yourself. So you turn to a math trick […]
As a gift for it fourth anniversary of its founding, China’s Origin Quantum set an ambitious roadmap with the development of a 1024-qubit quantum computer by 2025, according to computer-translated company statement. The announcement said […]
One postdoc would be working on Coherent Ising Machines (CIMs), the dynamics of coupled Optical Parametric Oscillators (OPOs) and related topics (including, e.g., topological photonics, quantum non-Hermitian dissipative dynamics, PT-symmetry in optics, etc.). Another postdoc […]
LIGENTEC, pioneer in high-performance, low-loss, silicon nitride photonic solutions, and specialty semiconductor producer X-FAB Silicon Foundries have announced a strategic partnership resulting in the large-scale supply of integrated photonic devices. Photonic integrated circuits (PICs) are […]
Scientists have observed that when the shape of a thin film of metal oxide known as titania is confined at the mesoscale, its conductivity increases. This finding demonstrates that nanoscale confinement is a way to […]
Quantum 5, 540 (2021). https://doi.org/10.22331/q-2021-09-13-540 We establish an analytical lower bound on the asymptotic secret key rate of continuous-variable quantum key distribution with an arbitrary modulation of coherent states. Previously, such bounds were only available […]
The next generation of computing and information processing lies in the intriguing world of quantum mechanics. Quantum computers are expected to be capable of solving large, extremely complex problems that are beyond the capacity of […]
