Rydberg atom interaction

WebIn cold-atom systems, Rydberg states have been used to create and coherently control non-classical states of light and atoms. Due to the large extent of the electron wavefunction hence the giant size of the Rydberg atoms, their dipole-dipole, and van-der-Waals interactions are very strong. WebOct 19, 2024 · Atomic arrays are well suited to store quantum information, and entanglement can be created using highly-excited Rydberg states. Typically, isolating pairs during gate operation is difficult because Rydberg interactions feature …
