High-dimensional entanglement between distant atomic-ensemble memories

2016 · Light Science & Applications

Entangled quantum states in high-dimensional space show many advantages compared with entangled states in two-dimensional space. The former enable quantum communication with higher channel capacity, enable more efficient quantum-information processing and are more feasible for …

Last-Iterate Convergent Policy Gradient Primal-Dual Methods for Constrained MDPs

2023 · arXiv (Cornell University)

We study the problem of computing an optimal policy of an infinite-horizon discounted constrained Markov decision process (constrained MDP). Despite the popularity of Lagrangian-based policy search methods used in practice, the oscillation of policy iterates …
