These archives each contain several different vi’s, and a .pdf file with documentation for all of them. Brief descriptions of the vi's are:
·
Coincidence.vi
This is the program we use to run 4 different experiments: simple coincidence
counting, measuring g(2)(0) with
a single beam and 2 detectors, measuring g(2)(0) with 2 beams and 3
detectors, and single photon interference.
·
Hardy-Bell.vi
This is the program we use for testing a Bell inequality, or for Hardy’s test
of local realism. The program can
accommodate either 2- or 4-detector measurements.
·
MCA.vi
This is the program we use to allow an A/D board to mimic the behavior of a
multichannel analyzer. We wrote this vi
because a multichannel analyzer is a fairly specialized piece of apparatus,
while A/D boards are more commonly found in undergraduate laboratories. (this
vi hasn’t been updated in a long time, and is not guaranteed to still
function.)
·
Coincidence_time_res.vi
Use this program to calibrate the time resolution of your coincidence
measurements. Needed for 2-detector g(2)(0) measurements and for
accidental coincidence subtraction.
·
Angle_scan.vi
Use this program to examine two photon polarization
correlations (joint probabilities) as a function of angle.
·
QSM_rs232.vi
Used to measure the polarization state of a
single photon.

LabView V. 2019 vi’s for DE2 Coincidence Unit (from 2021)
These vi’s can use either the Whitman DE2 coincidence counter, or the Red Dog CD48 coincidence counter to acquire data. For interference experiments, we have updated the vi’s to use the Thorlabs Z806 DC servo motor (the NewStep linear stepper is no longer supported). For Hardy and Bell experiments vi's support the Newport NewStep rotation stages (NSR1); and have been updated to include a “Manual” mode to allow for manual setting of the rotation stages.
Click here LabView 2019 DE2-CD48 to download a .zip archive containing these vi’s. These vi’s are all native LabView 2019 code.

LabView V. 2015 vi’s for DE2 Coincidence Unit (from 2016)
These vi’s were written to use the Whitman DE2 coincidence counter to acquire data. Data streams from this counter to the computer over an RS-232 serial port. These vi's support the Newport NewStep rotation stages (NSR1); and have been updated to include a “Manual” mode to allow for manual setting of the rotation stages.

Simple executable .vi for DE2 Coincidence Unit (from 2013)
A Windows installer that installs Coincidence.vi; it uses the Whitman DE2 coincidence counter to acquire data. Data streams from this counter to the computer over an RS-232 serial port. This vi will support the Newport NewStep stepper motor, but you don’t need a stepper motor to run it (simply leave “NewStep?” set to “No”). All you need to set is the COM port connecting to the DE2 and you’re good to go. Full documentation is available with the regular labview code here.

LabView V. 2011 vi’s for DE2 Coincidence Unit (from 2012)
These vi’s were written to use the Whitman DE2 coincidence counter to acquire data. Data streams from this counter to the computer over an RS-232 serial port. These vi's have been updated to support the Newport NewStep rotation stages (NSR1). They also include a new program to perform quantum state measurement.

LabView V. 8.2 vi’s for DE2 Coincidence Unit (from 2008)
These vi’s were written to use the Whitman DE2 coincidence counter to acquire data. Data streams from this counter to the computer over an RS-232 serial port.

LabView V. 8.2 vi’s for PCI-6602 (from 2007)
These vi’s were written to use the National Instruments PCI-6602 counter to acquire data. They will work with TAC/SCA coincidence determination, or with the Trinity/Whitman discrete IC coincidence circuit.
Click here LabView 8.2 to download a .zip archive containing the vi’s for Labview version 8.2. These vi’s are sort of a kludge. They were converted from LabView 7 by saving all the vi’s (including those from the vi.lib). They don’t use the native LabView 8 data acquisition routines (DAQmx).

Original LabView V. 7 vi’s (from 2006)
These vi’s were written to use the National Instruments PCI-6602 counter to acquire data. They will work with TAC/SCA coincidence determination, or with the Trinity/Whitman discrete IC coincidence circuit.
