Discretized Gaussian Modulation-Based Continuous Variable (CV)-QKD [PDF]

open access: yes2019 IEEE Photonics Conference (IPC), 2019
To overcome the low-reconciliation-efficiency problem of Gaussian modulation (GM)-based-CV-QKD, we propose to use discretized-GM-based-CV-QKD. This scheme has complexity and reconciliation-efficiency similar to discrete modulation (DM)-based-CV-QKD and at the same time solves for the problem of nonexistence of strict security proofs for DM-CV-QKD under

Ultracompact Generation of Continuous-Variable Cluster States [PDF]

open access: yes, 2007
We propose an experimental scheme that has the potential for large-scale realization of continuous-variable (CV) cluster states for universal quantum computation.

Climate variability and trends in the Endorheic Lake Hayk basin: implications for Lake Hayk water level changes in the lake basin, Ethiopia

open access: yesEnvironmental Systems Research, 2022
For sustainable climate hazard management, climate information at the local level is crucial for developing countries like Ethiopia, which has an exceptionally low adaptive capacity to changes in climate.

Entanglement reciprocation between qubits and continuous variables [PDF]

open access: yes, 2005
We investigate how entanglement can be transferred between qubits and continuous variable (CV) systems. We find that one ebit borne in maximally entangled qubits can be fully transferred to two CV systems which are initially prepared in pure separable ...

Optimal continuous-variable teleportation under energy constraint [PDF]

open access: yes, 2017
Quantum teleportation is one of the crucial protocols in quantum information processing. It is important to accomplish an efficient teleportation under practical conditions, aiming at a higher fidelity desirably using fewer resources.

A learning theory for quantum photonic processors and beyond [PDF]

open access: yesQuantum
We consider the tasks of learning quantum states, measurements and channels generated by continuous-variable (CV) quantum circuits. This family of circuits is suited to describe optical quantum technologies and in particular it includes state-of-the-art ...

Flexible quantum circuits using scalable continuous-variable cluster states [PDF]

open access: yes, 2016
We show that measurement-based quantum computation on scalable continuous-variable (CV) cluster states admits more quantum-circuit flexibility and compactness than similar protocols for standard square-lattice CV cluster states.

Continuous variable entanglement on a chip

open access: yes, 2015
Encoding quantum information in continuous variables (CV)---as the quadrature of electromagnetic fields---is a powerful approach to quantum information science and technology.

Accumulation of entanglement in a continuous variable memory [PDF]

open access: yes, 2006
We study the accumulation of entanglement in a memory device built out of two continuous variable (CV) systems. We address the case of a qubit mediating an indirect joint interaction between the CV systems. We show that, in striking contrast with respect
