Sub-second production of a quantum degenerate gas

Understand

Realizing faster experimental cycle times is important for the future of quantum simulation.

• The cycle time determines how often the many-body wave-function can be sampled, defining the rate at which information is extracted from the quantum simulation.
• We demonstrate a system which can produce a Bose-Einstein condensate of $8 \times 10^4$ $^{168}\text{Er}$ atoms with approximately 85% condensate fraction in 800 ms and a degenerate Fermi gas of $^{167}\text{Er}$ in 4 seconds, which are unprecedented times compared to many existing quantum gas experiments.
• This is accomplished by several novel cooling techniques and a tunable dipole trap.
