Continuousvariable quantum cloning of coherent states with phaseconjugate input modes using linear optics
Abstract
We propose a scheme for continuousvariable quantum cloning of coherent states with phaseconjugate input modes using linear optics. The quantum cloning machine yields M identical optimal clones from N replicas of a coherent state and N replicas of its phase conjugate. This scheme can be straightforwardly implemented with the setups accessible at present since its optical implementation only employs simple linear optical elements and homodyne detection. Compared with the original scheme for continuousvariable quantum cloning with phaseconjugate input modes proposed by Cerf and Iblisdir [Phys. Rev. Lett. 87, 247903 (2001)], which utilized a nondegenerate optical parametric amplifier, our scheme loses the output of phaseconjugate clones and is regarded as irreversible quantum cloning.

We investigate the security of continuousvariable quantum key distribution using coherent states and reverse reconciliation against Gaussian individual attacks based on an optimal Gaussian 1{yields}2 cloning machine. We provide an implementation of the optimal Gaussian individual attack. We also find a Bellmeasurement attack which works without delayed choice of measurements and has better performance than the cloning attack.

Generalization of continuousvariable quantum cloning with linear optics
We propose an asymmetric quantum cloning scheme. Based on the proposal and experiment by Andersen et al. [Phys. Rev. Lett. 94, 240503 (2005)], we generalize it to two asymmetric cases: quantum cloning with asymmetry between output clones and between quadrature variables. These optical implementations also employ linear elements and homodyne detection only. Finally, we also compare the utility of symmetric and asymmetric cloning in an analysis of a squeezedstate quantum key distribution protocol and find that the asymmetric one is more advantageous. 
Efficientphaseencoding protocols for continuousvariable quantum key distribution using coherent states and postselection
We propose efficientphaseencoding protocols for continuousvariable quantum key distribution using coherent states and postselection. By these phase encodings, the probability of basis mismatch is reduced and total efficiency is increased. We also propose mixedstate protocols by omitting a part of classical communication steps in the efficientphaseencoding protocols. The omission implies a reduction of information to an eavesdropper and possibly enhances the security of the protocols. We investigate the security of the protocols against individual beam splitting attack. 
Temporalmode continuousvariable cluster states using linear optics
An extensible experimental design for optical continuousvariable cluster states of arbitrary size using four offline (vacuum) squeezers and six beam splitters is presented. This method has all the advantages of a temporalmode encoding [Phys. Rev. Lett. 104, 250503 (2010)], including finite requirements for coherence and stability even as the computation length increases indefinitely, with none of the difficulty of inline squeezing. The extensibility stems from a construction based on Gaussian projected entangled pair states. The potential for use of this design within a fully faulttolerant model is discussed. 
Security of continuousvariable quantum cryptography using coherent states: Decline of postselection advantage
We investigate the security of continuousvariable (CV) quantum key distribution (QKD) using coherent states in the presence of quadrature excess noise. We consider an eavesdropping attack that uses a linear amplifier and a beam splitter. This attack makes a link between the beamsplitting attack and the interceptresend attack (classical teleportation attack). We also show how postselection loses its efficiency in a realistic channel.
