Abstract

Optical implementations of qubits play an important role for quantum information science. Photons are ideal carriers of quantum information due to low decoherence rates and are easily controllable by standard off‐the‐shelf components. Over the last decade the degree of control over photonic single‐ and two‐qubit operations has improved substantially, which recently enables the complex state engineering of various multi‐photon states. The control of current four‐ and six‐photon entangled states provides access for the investigation of interesting properties of multi‐particle entangled states and for overcoming the random nature of spontaneous emission sources.
