or
i representation initially we sure where a person and where you can tell you about
a quarter was also power michael however
the paper is control of conditional one i think i do the clearance
our experiment is less crime interference between indistinguishable pass
to demonstrate ground state one
we have data with this electronic interview little structure to available at that time each
with three d models splits at levels with energy splitting dot e
we start in a single zero ground state in
by one or like we can try transition to and that was your state right
after characteristic a time
that indicate that are the grass to mandible and a simple song
conservation of momentum allows to indicate that is
and want to be here are those people's plusminus one states
using coordination measurements a new method works on
you can build rather than which electronically to an angle
however are correlation interests cannot tell us which individual little electronic and it's a superposition
unit was minus one states
conditional on the detection of appropriate
and seventy absorption of another over time from the right is or
that is part of the superposition involves frequency proportional to energy splitting
which is the opposite sign for each state in the superposition
problems portion of the time from the try
the superposition is coherently cited
and stress first right now
finally the atom to separate
you single iteration measurements you'd order out of photons which hero indicate that and that
equals your state
the probability of this occurring equal to this where users you amplitude
would you can be induced interference between arts assigned a solutions of the components of
the relative position
our data reflects the probability measure that conditional on the detection of first which pair
of the relative position
the data exhibits quantity into which gives as a measure of the coherence in the
ground state position
andreas number one at a more of our experimental and how women feedback mechanism to
preserve coherence in the ground station
this interference correspondingly that chris us introduce a can be experimentally realise using for example
we have any five times which we can obtain
to anatomically i and working i will explain a little bit more about the experimental
part
so we practise religion doesn't come nearly individually a pitch in little boxes run time
i and so we use an alternate approach
what we actually is the device that produces that these are
and with an arrangement of lisa's a nine year old we only use quite intimate
contact e
we just analyzer small problem this task it but doesn't make the left and right
many atoms that time and the outgoing what would be a scatter masks and i
s
so that we rely on a clever sure that uses something called not compactly and
i'll go values just basically information to two years facing each other
and when you shine light on the one last time for many times and a
dash
with this configuration we can wait for a single but in this brochure the on
that selecting the interaction between the driver but constantly at the gap also serve to
final the one that the atoms of this makes it much easier to master in
a systematic way
the driver's on israeli for instance interaction with the atom is characterized by the release
of the segments are for the
as long as the cavity we filter out the polarised right but on polarised and
time step derive a limited but
this process is iterated thousands of times second for different items and the interference can
be as their statistical this during an appearance that indicates over time due to environmental
and that is what we can't control
so what we actually not doing with our experiment is we use one of our
detectors to do some feedback on our experiments where we chernoff momentarily are directly so
this has the effect of increased amplitude on the interference pattern you saw before
a two factors to a which translates to are superposition living longer in the in
protected against something covariance processes
ultimately what we wanna do with our experiment is trying to preserve the superposition as
long as possible
many people especially in the information area are interested in using a function positions
two
that story information they wanna map some information store in light for example in to
a
into the electronic energy level of and then extract that back and forth hans and
then built in this week one networks and other devices
our goal for this experiment was simply to keep the superposition i alive this long
as possible with a fast very simple feedback
