Entangled-Photon Imaging of a Pure Phase Object
Ayman F. Abouraddy, Patrick R. Stone, Alexander V. Sergienko +2
We demonstrate experimentally and theoretically that a coherent image of a pure phase object may be obtained by use of a spatially incoherent illumination beam. This is accomplishe…
Symmetric Autocompensating Quantum Key Distribution
Zachary D. Walton, Alexander V. Sergienko, Lev B. Levitin +2
We present quantum key distribution schemes which are autocompensating (require no alignment) and symmetric (Alice and Bob receive photons from a central source) for both polarizat…
Entanglement, Mixedness, and Spin-Flip Symmetry in Multiple-Qubit Systems
Gregg Jaeger, Alexander V. Sergienko, Bahaa E. A. Saleh +1
A relationship between a recently introduced multipartite entanglement measure, state mixedness, and spin-flip symmetry is established for any finite number of qubits. It is also s…
Observation of bosonic coalescence of photon pairs
Giovanni Di Giuseppe, Mete Atature, Matthew D. Shaw +6
Quantum theory predicts that two indistinguishable photons incident on a beam-splitter interferometer stick together as they exit the device (the pair emerges randomly from one por…
Demonstration of Dispersion-Cancelled Quantum-Optical Coherence Tomography
Magued B. Nasr, Bahaa E. A. Saleh, Alexander V. Sergienko +1
We present an experimental demonstration of quantum optical coherence tomography (QOCT). The technique makes use of an entangled twin-photon light source to carry out axial optical…
Decoherence-Free Subspaces in Quantum Key Distribution
Zachary D. Walton, Ayman F. Abouraddy, Alexander V. Sergienko +2
We demonstrate that two recent innovations in the field of practical quantum key distribution (one-way autocompensation and passive detection) are closely related to the methods de…
