Qkd s strength lies in the fact that anyone attempting to eavesdrop on the key will be caught. Our team at nus will bring in expertise on the theory protocol design and proof of concept experiments of the quantum random number generator and qkd systems.

The team showed that secure quantum key exchange could be accomplished between two chip based devices measuring just 6 2 mm over a fiber network with links up to 200 km.
Qkd on chip. Fabian beutel university of münster institute of physics 48149 münster germany. An on chip continuous variable quantum key distribution cv qkd system is integrated using silicon photonics fabrication process and demonstrates the capability of transceiving gaussian modulated coherent states and homodyne detection. In qkd quantum properties of photons such as polarization state and entanglement are used to create cryptographic keys.
A research team at the university of bristol has demonstrated chip based devices that contain all the optical components necessary for quantum key distribution qkd. Improvement in secure transmission of information is an urgent practical need for governments corporations and individuals. In this work we present a qkd transmitter chip that exploits the direct phase modulation approach recently introduced in bulk optics transmitters16.
Chip phase encoding free of such modulators is highly desirable as it would increase the scaling capacity and reduce the power footprint of qkd systems at the same time. Charles lim assistant professor at nus said. Despite these advances qkd has not been widely adopted and practical large.
So we are now working on chip based next generation systems and protocols such as floodlight qkd measurement device independent qkd and hybrid classical quantum systems developing these to feed into the growing ecosystem of companies and iscf projects. For practical applications there is increasing attention to integrating the source detectors and modulators on a photonic chip. Helge gehring university of münster institute of physics 48149 münste.
Quantum key distribution qkd can distribute symmetric key bits between remote legitimate users with the guarantee of quantum mechanics principles. Quantum key distribution qkd promises security based on the laws of physics and has rapidly grown from proof of concept to robust demonstrations and even deployment of commercial systems. The development of chip based prototypes will allow us to turn today s qkd technologies into an efficient communication networking solution.
Quantum key distribution qkd is a secure communication method which implements a cryptographic protocol involving components of quantum mechanics it enables two parties to produce a shared random secret key known only to them which can then be used to encrypt and decrypt messages it is often incorrectly called quantum cryptography as it is the best known example of a quantum cryptographic. These keys in turn are used to establish safe communication channels.
