Polarization Basis

Main Question or Discussion Point

I have a quick, general, query.

When conducting an experiment with entangled photons, measuring in the +/- basis would mean in the 45/135 basis?

I don't think I've seen that notation before (45/135 associated with +/-).

Same. I am just wondering what the basis is also known as. I'm referring to the delayed choice entanglement swapping experiment from 2012. They denote polarization, when a bell-state measurement occurred, as |+> and |->

Found the answer: it is indeed denoting the |45> and |135> basis. Thank you, 'The Quantum Divide' by Chris Gerry, pg. 111.
