| # **Project Team:** - Benjamin Kassel (bkassel2) - Andrew Situ (asitu2) - Ian Skirkey (skirkey2) - Professor Kwait # **Problem:** We’d like to create an ‘entanglement simulator’ for public demonstrations and outreach. We will work with Professor Kwait to create a device that can should be able to demonstrate Quantum Entanglement in a fun, educational way that can be displayed in the ECEB or the Physics building. # **Solution (Idea Post from Professor Kwait):** The Educational Entanglement Device: It would feature a central ’source’, out of which come two LED strings, in opposite directions. Correlated light pulses would travel down each string (visible to the observers). The participants could then ‘measure’ the pulses in one of a couple different ways (by touching the strands in a particular way — students would have to figure out the best way to do this, using capacitive switches, pressure sensors, etc [it's a bit nontrivial, since we'd like the participants to be able to touch anywhere along a ~3' stretch of the string, but with ~1" resolution of where they touched]), yielding one of a couple results (in accordance with quantum mechanics). These would then be shown on a local display to each of the participants. In addition to demonstrating the basic correlations of entanglement, such a system can also implement a basic quantum cryptography protocol. If the two participants make the same type of measurement, they get the same (but random) result. These can then be used to generate a shared random key, which the project could then use to allow them to send a short encrypted message ("one-time pad"). This could be done by having touch capacitive sensors and pressure sensors all along the two 3' LED strips which would terminate at two LED display. The different inputs from the capacitive sensors and pressure sensors would be forwarded to a control board if the light pulse and the input from the user overlap to demonstrate the users measurement of the 'particle'. The control board would then modify the initial output of the light pulses depending on the user input to illustrate how measuring the light pulses would change the 'particle's' output onto the two displays. The input would be based on the different capacitive touch and pressure inputs ran through some deterministic algorithm so that the same action performed in the same location would output the same throughout the runs to illustrate the basic quantum cryptography. # **Solution Components:** **Educational Interface module:** -Local Displays: 2 displays to demonstrate quantum entanglement’s message being received on 2 different locations -Touch Sensors (Capacitive touch sliders): Sensors to allow participants to affect the LED’s in the demonstration of quantum entanglement -LEDs: Lights used to illustrate the light pulses **Controller Module:** -Control Board: Receives and interprets all of the data from the touch sensors and digitally affects the ‘measurement’ of the entangled particle which would then be outputted on the displays. -Network Interface: Connection between the two different displays to authenticate the same message would be displayed at the same time. # **Success Criterion:** It would be important to push the project through to a final ’nice’ robust system. We would also want the device to not look out of place in an ECE building, and also be able to educate those less familiar with quantum entanglement |
