Experimental Description/Abstract:
By conducting the inaugural Project QUERB experiment, we seek to advance quantum physics
research through the means of manipulating multiple particles — by changing the state of a
single particle — instantaneously. The practical justification through our findings with this
experiment may further develop quantum technologies and real-life applications of quantum
inventions which may eventually be powerfully applied to everyday use.
Equipment:
MOT Equipment
Description:
The atomic refrigerator which cools the atoms to an extremely low
temperature in the micro kelvins. At these low temperatures we
can then begin to entangle the atoms.
miniMOT (Vacuum System, Dispenser, Ion Pump, Dispenser Current Supply)
Description |
The miniMOT is a magneto-optical trap system which traps and
cools atoms to a level at which we can manipulate them for our
experiment. |
Purpose |
We can load rubidium-87 atoms into the MOT to be cooled
for experimental use. Once this is complete, we can begin
to entangle the cooled atoms by shooting a laser pulse
through the MOT system. |
