Abstract Cold atoms are important for precision atomic applications including timekeeping and sensing. The 3D magneto-optical trap (3D-MOT), used to produce cold atoms, will benefit from photonic integration to improve reliability and reduce size, we

We present a method for network-capable quantum computing that relies on holographic spin-wave excitations stored collectively in ensembles of qubits. We construct an orthogonal basis of spin waves in a one-dimensional array and show that high-fideli

Electric field sensors based on Rydberg atoms offer unique capabilities, relative to traditional sensors, for detecting radio-frequency signals. In this work, we demonstrate simultaneous demodulation and detection of five rf tones spanning nearly two

We demonstrate an integrated photonics infrastructure for atomic laser cooling. We trap 5 x 106 87Rb atoms in a magneto-optical trap using free-space cooling beams emitted from a SiN photonic integrated circuit.

Holographic spin-wave excitations in atoms are commonly used to build high-performance quantum memories. Here we show three methods that enable not just storage, but universal quantum computing, with atomic spin waves.

Quantum sensors offer the capability to reach unprecedented precision by operating at the standard quantum limit (SQL) or beyond by using quantum entanglement. But an emerging class of quantum sensors that use Rydberg electromagnetically induced tran

Vertical external-cavity surface-emitting lasers (VECSELs) augmented by intra-cavity nonlinear optical frequency conversion have emerged as an attractive light source of ultraviolet to visible light for demanding scientific applications, relative to

The electromagnetic spectrum is limited. As demand increases, our capabilities will be dictated by the sensitivity and agility of RF transmitters, receivers, and networks. For this reason, quantum RF sensors and networks are the key to controlling th

We demonstrate an atomic radio-frequency (RF) receiver and spectrum analyzer based on thermal Rydberg atoms coupled to a planar microwave waveguide. We use an off-resonant RF heterodyne technique to achieve continuous operation for carrier frequencie

The optimal performance for Rydberg quantum sensing with vapor cell three-level coherent spectroscopy (e.g. EIT, CPT) is modeled and compared with the standard quantum limit. Potential gains with four-level schemes are discussed.
