Joining the quantum state of two photons into one
Photons are the ideal carriers of quantum information for communication1,2. Each photon can have a single or multiple qubits encoded in its internal quantum state, as defined by optical degrees of freedom such as polarization, wavelength, transverse modes and so on3,4. However, as photons do not interact, multiplexing and demultiplexing the quantum information across photons has not been possib...
متن کاملA Simplified and Reproducible Two-Step Method for the Purification of Prostate-Specific Antigen
Prostate-specific antigen (PSA) was purified to homogeneity from human seminal plasma by ion-exchange chromatography on a CM-Sephadex C-50 and by gel filtration on a Sephacryl S-200 column. A single 33-kDa protein band appeared in SDS-PAGE. High pressure liquid chromatography (HPLC) of the purified protein produced a single peak, while isoelectric focusing demonstrated the presence of five diff...

متن کاملHyperentanglement for advanced quantum communication
Quantum entanglement is known to enable otherwise impossible feats in various communication protocols, such as quantum key distribution and super-dense coding. Here we describe efforts to further enhance the usual benefits, by incorporating quantum states that are simultaneously entangled in multiple degrees of freedom – “hyperentangled”. Via the process of spontaneous parametric down conversio...
