Maximally entangled mixed states: Creation and concentration
Nicholas A. Peters, Joseph B. Altepeter, David A. Branning +3
Using correlated photons from parametric downconversion, we extend the boundaries of experimentally accessible two-qubit Hilbert space. Specifically, we have created and characteri…
Ancilla-assisted quantum process tomography
J. B. Altepeter, D. Branning, E. Jeffrey +6
Complete and precise characterization of a quantum dynamical process can be achieved via the method of quantum process tomography. Using a source of correlated photons, we have imp…
Taming Entanglement
Paul Kwiat, Joe Altepeter, David Branning +3
Using a spontaneous parametric-downconversion source of photon pairs, we are working towards the creation of arbitrary 2-qubit quantum states with high fidelity. Currently, all phy…
