Single ion-qubit exceeding one hour coherence time
Pengfei Wang, Chun-Yang Luan, Mu Qiao +7
Realizing a long coherence time quantum memory is a major challenge of current quantum technology. Here, we report a single \Yb ion-qubit memory with over one hour coherence time,…
Randomness expansion secured by quantum contextuality
Mark Um, Qi Zhao, Junhua Zhang +6
The output randomness from a random number generator can be certified by observing the violation of quantum contextuality inequalities based on the Kochen-Specker theorem. Contextu…
Testing nonclassicality and non-Gaussianity in phase space
Jiyong Park, Junhua Zhang, Jaehak Lee +5
We theoretically propose and experimentally demonstrate a nonclassicality test of single-mode field in phase space, which has an analogy with the nonlocality test proposed by Banas…
State-independent experimental tests of quantum contextuality in a three dimensional system
Xiang Zhang, Mark Um, Junhua Zhang +6
We experimentally observed state-independent violations of Kochen-Specker inequalities for the simplest indivisible quantum system manifesting quantum contextuality, a three-level…
