100 MHz Amplitude and Polarization Modulated Optical Source for Free-Space Quantum Communications at 850 nm
We report on an 100 MHz repetition rate integrated photonic transmitter at 850 nm with arbitrary amplitude and polarization modulation. The source is suitable for free-space quantum communication links, in particular for quantum key distribution applications. The whole transmitter, with the optical and electronic components integrated, has reduced size and power consumption. In addition, the op...
متن کاملFree-space quantum key distribution
Quantum cryptography was introduced in the mid1980s [1] as a new method for generating the shared, secret random number sequences, or cryptographic keys, that are used in crypto-systems to provide communications security. The appeal of quantum cryptography is that its security is based on laws of Nature, in contrast to existing methods of key distribution that derive their security from the per...
متن کاملFree-Space Quantum Key Distribution
Quantum key distribution is the most advanced technology to arise from the emerging field of quantum information. In fact, a few companies (MaqiQ Technologies and id Quantique) already offer commercial quantum key distribution products. But why so much excitement over QKD when our standard techniques serve just fine? Well the thing is that our standard techniques are safe only under certain ass...
متن کاملFree-Space Optical Quantum Key Distribution Using Intersatellite Links
Communication schemes employing quantum entanglement open a wide field of possible applications with properties outperforming their classical counterparts. Promising examples are quantum key distribution, quantum dense coding, and quantum state teleportation. We investigate the potential of quantum cryptography, i.e. quantum key distribution (QKD), with special emphasis on the demands and oppor...
متن کاملTime-cost analysis of a quantum key distribution system clocked at 100 MHz.
We describe the realization of a quantum key distribution (QKD) system clocked at 100 MHz. The system includes classical postprocessing implemented via software, and is operated over a 12 km standard telecommunication dark fiber in a real-world environment. A time-cost analysis of the sifted, error-corrected, and secret key rates relative to the raw key rate is presented, and the scalability of...
