Telecom-band-integrated multimode photonic quantum-memory

 Quantum Physics News
 31 July 2023
Quantum memory that depends on quantum-band integration is a key building block used to develop quantum networks that are compatible with fiber communication infrastructures. Quantum engineers and IT specialists have yet to create such a network with large capacity to form an integrated multimode...

A team led by Prof. Li Chuanfeng and Prof. Xu Jinshi from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), collaborating with Prof. Chen Jingling from Nankai University and Prof. Adán Cabello from the University of Seville, studied the single-system...

Quantum interference can protect and enhance photoexcitation

 Quantum Physics News
 21 June 2023
When a photon interacts with a material, an interaction occurs that causes its atoms to change their quantum state (a description of the physical properties of nature at the atomic level). The resulting state is called, aptly, photoexcitation. These photoexcitations are conventionally assumed to...
