Annealing reduces SiN microwave-frequency dielectric loss in superconducting resonators
Sarang Mittal, Kazemi Adachi, Nicholas E. Frattini +10
The dielectric loss of silicon nitride (SiN) limits the performance of microwave-frequency devices that rely on this material for sensing, signal processing, and quantum co…
Verifying multi-partite mode entanglement of W states
Pavel Lougovski, S. J. van Enk, Kyung Soo Choi +3
We construct a method for verifying mode entanglement of N-mode W states. The ideal W state contains exactly one excitation symmetrically shared between N modes, but our method tak…
Bragg spectroscopy of a strongly interacting 85Rb Bose-Einstein condensate
S. B. Papp, J. M. Pino, R. J. Wild +4
We report on measurements of the excitation spectrum of a strongly interacting Bose-Einstein condensate (BEC). A magnetic-field Feshbach resonance is used to tune atom-atom interac…
Two-species magneto-optical trap with 40K and 87Rb
J. Goldwin, S. B. Papp, B. DeMarco +1
We trap and cool a gas composed of 40K and 87Rb, using a two-species magneto-optical trap (MOT). This trap represents the first step towards cooling the Bose-Fermi mixture to quant…
Pauli Blocking of Collisions in a Quantum Degenerate Atomic Fermi Gas
B. DeMarco, S. B. Papp, D. S. Jin
We have produced an interacting quantum degenerate Fermi gas of atoms composed of two spin-states of magnetically trapped K. The relative Fermi energies are adjusted by cont…
