The NIST Ion Storage Group conducts research on various aspects of quantum information and precision measurement using trapped ions. Their work focuses on three main areas:
1. Precision Metrology: The group uses trapped ions to measure optical frequencies with high precision, enabling applications in optical clocks, fundamental physics research, and relativistic geodesy.
2. Quantum Control and Computing: They develop new architectures and technologies to improve the fidelity and scalability of quantum control and readout for quantum computing based on trapped ions in radio-frequency traps.
3. Quantum Simulation and Sensing: The group uses magnetic and electric fields in Penning traps to confine two-dimensional Coulomb crystals of ions, allowing them to perform quantum simulations of many-body spin Hamiltonians and sense electric fields below the standard quantum limit using quantum mechanical squeezing.
Additionally, the group is working on generating high-fidelity remote entanglement between trapped ion qubits using telecom photons, with a focus on using an ion-trap-integrated fiber Fabry-Pérot cavity for efficient entanglement generation between ions and telecom photons.
