USTC Fabricates Integrable Solid-State Quantum Memories with...[2020-03-11]
Mapping quantum information between light and matter, optical quantum memories are crucial devices in large-scale quantum networks. Based on bulk rare-earth-ion-doped crystals, quantum memories with high fidelity, multi-mode capacity and long storage time can be demonstrated. 151Eu3+-doped yttrium silicate (151Eu3+ : Y2SiO5) crystal is an attractive candidate for this. However, there hav... -
Coherent Phonon Dynamics Realized in Spatially Separated Mec...[2020-03-04]
The CAS Key Laboratory of Quantum Information makes a significant progress in nanomechanical resonators. A group led by Prof. GUO Guo-Ping, SONG Xiang-Xiang, DENG Guang-Wei (now at UESTC) in collaboration with Prof. TIAN Lin from University of California, Merced, and Origin Quantum Company Limited realized coherent phonon manipulations within spatially separated mechanical resonators. The research...

The recent progress on a spin-orbit coupled Mott insulator[2019-12-11]
A central theme in condensed matter physics is to observe and understand the exotic quantum phenomena in doped Mott insulators. A famous example of doped Mott insulators is the cuprate high-temperature superconductors. In cuprates, there are three important players – the pseudogap, d-wave superconductivity, and electron-boson coupling. The pseudogap phase is intertwined with d-wave superconductivi...

Space Dragons: Researchers Observe Energy Consumption in Qua...[2019-09-05]
Quasars are the Universe’s brightest beacons; shining with magnitudes more luminosity than entire galaxies and the stars they contain. In the center of this light, at the heart of a quasar, researchers think, is an all-consuming black hole.Researchers, for the first time, have observed the accelerated rate at which eight quasars consume interstellar fuel to feed their black holes.They published t...
