Secure quantum key distribution using continuous variables of single photons.
We analyze the distribution of secure keys using quantum cryptography based on the continuous variable degree of freedom of entangled photon pairs. We derive the information capacity of a scheme based on the spatial entanglement of photons from a realistic source, and show that the standard measures of security known for quadrature-based continuous variable quantum cryptography (CV-QKD) are ina...
متن کاملQuantum Bit Error Rates in Quantum Key Distribution Using Entangled Photons
Quantum key distribution, often known as quantum cryptography, is a proposed practical application of quantum mechanics, based on the uncertainty principle. A cryptographic key is transmitted by encoding it in the quantum state of a series of photons, the receiver measuring each photon in one of several bases selected at random. Only those measurements made in a basis compatible with the prepar...
متن کاملFree-space quantum key distribution by rotation-invariant twisted photons.
"Twisted photons" are photons carrying a well-defined nonzero value of orbital angular momentum (OAM). The associated optical wave exhibits a helical shape of the wavefront (hence the name) and an optical vortex at the beam axis. The OAM of light is attracting a growing interest for its potential in photonic applications ranging from particle manipulation, microscopy, and nanotechnologies to fu...
متن کاملQuantum key distribution using quantum Faraday rotators.
We propose a new quantum key distribution (QKD) protocol based on the fully quantum mechanical states of Faraday rotators. The protocol is unconditionally secure against collective attacks for a multi-photon source of up to two photons on a noisy environment. It is also robust against impersonation attacks. The protocol may be implemented experimentally with the current spintronics technology o...
