Quantum Computing

We are exploring the use of neutral atoms for quantum information processing using several related but complementary approaches. Experiments are underway with three dfferent atomic species: Rb, Cs, and Ho.

Rb: Rydberg blockade for atom-atom and atom-photon entanglement

Cs: single atom qubit array

Cs: holographic atom traps

Ho: laser cooling and collective encoding

Hybrid quantum interfaces
