Qudit implementations with energy-time entangled photons
Bänz Bessire, Christof Bernhard, Thomas Feurer, André Stefanov · Research in Optical Sciences · 2014
We demonstrate qudit encoding in the spectrum of energy-time entangled photons by means of pulse shaping techniques known from ultra-fast laser physics. Quantum state tomography up to d = 4 and Bell test measurements are performed.
