Implementing a neutral-atom controlled-phase gate with a single Rydberg pulse
Rui Han, Hui Khoon Ng, Berthold-Georg Englert
One can implement fast two-qubit entangling gates by exploiting the Rydberg blockade. Although various theoretical schemes have been proposed, experimenters have not yet been able…
Monte Carlo sampling from the quantum state space. II
Yi-Lin Seah, Jiangwei Shang, Hui Khoon Ng +2
High-quality random samples of quantum states are needed for a variety of tasks in quantum information and quantum computation. Searching the high-dimensional quantum state space f…

Quantum state tomography: Mean squared error matters, bias does not
Jiangwei Shang, Hui Khoon Ng, Berthold-Georg Englert
Because of the constraint that the estimators be bona fide physical states, any quantum state tomography scheme - including the widely used maximum likelihood estimation - yields e…
Experimental detection of entanglement with optimal-witness families
Jibo Dai, Yink Loong Len, Yong Siah Teo +2
We report an experiment in which one determines, with least tomographic effort, whether an unknown two-photon polarization state is entangled or separable. The method measures whol…
