Hyperentangled Bell-state analysis
Tzu-Chieh Wei, Julio T. Barreiro, Paul G. Kwiat
It is known that it is impossible to unambiguously distinguish the four Bell states encoded in pairs of photon polarizations using only linear optics. However, hyperentanglement, t…
Remote state preparation: arbitrary remote control of photon polarization
Nicholas A. Peters, Julio T. Barreiro, Michael E. Goggin +2
We experimentally demonstrate the first remote state preparation of arbitrary single-qubit states, encoded in the polarization of photons generated by spontaneous parametric downco…
Measurement of geometric phase for mixed states using single photon interferometry
Marie Ericsson, Daryl Achilles, Julio T. Barreiro +3
Geometric phase may enable inherently fault-tolerant quantum computation. However, due to potential decoherence effects, it is important to understand how such phases arise for {\i…
