Energy-time entangled qutrits: Bell tests and quantum communication
We have developed a scheme to generate, control, transmit and measure entangled photonic qutrits (two photons each of dimension d = 3). A Bell test of this source has previously been reported elsewhere [1], therefore, here we focus on how the control of the system is realized. Motivated by these results, we outline how the scheme can be used for two specific quantum protocols, namely key distri...
متن کاملExperimental Violation of Multisetting Bell Inequalities for Qudits using Energy-Time Entangled Photons
The non-locality of nature is one of the most profound notions of quantum mechanics (QM) and is closely related to the phenomena of entanglement. The latter occurs when a quantum state of at least two particles cannot be written as independent single particle states. The manifestation of entanglement can be observed by correlations between two systems with no classical analogue. Moreover, these...
متن کاملLong-Distance Quantum Communication With Entangled Photons Using Satellites
The use of satellites to distribute entangled photon pairs (and single photons) provides a unique solution for long-distance quantum communication networks. This overcomes the principle limitations of Earth-bound technology, i.e., the range of the order of 100 km afforded by both optical fiber and by terrestrial free-space links.

متن کاملResonant sum frequency generation with time-energy entangled photons.
We describe a technique for enhancing the efficiency of sum frequency generation using entangled signal and idler photons. By resonating the sum frequency field, we observe that the generated power varies linearly with input power and is increased by a factor of 12.
