Continuous-variable quantum neural networks

open access: yesPhysical Review Research, 2019
We introduce a general method for building neural networks on quantum computers. The quantum neural network is a variational quantum circuit built in the continuous-variable (CV) architecture, which encodes quantum information in continuous degrees of ...

Atmospheric continuous-variable quantum communication [PDF]

open access: yesNew Journal of Physics, 2014
We present a quantum communication experiment conducted over a point-to-point free-space link of 1.6 km in urban conditions. We study atmospheric influences on the capability of the link to act as a continuous-variable (CV) quantum channel.

Continuous-Variable Quantum State Designs: Theory and Applications [PDF]

open access: yesPhysical Review X
We generalize the notion of quantum state designs to infinite-dimensional spaces. We first prove that, under the definition of continuous-variable (CV) state t-designs from [Blume-Kohout et al., Commun. Math. Phys.

Continuous-variable quantum state designs: theory and applications

open access: yes, 2022
We generalize the notion of quantum state designs to infinite-dimensional spaces. We first prove that, under the definition of continuous-variable (CV) state $t$-designs from Comm. Math. Phys.

Quantum computing overview: discrete vs. continuous variable models [PDF]

open access: yes, 2022
In this Near Intermediate-Scale Quantum era, there are two types of near-term quantum devices available on cloud: superconducting quantum processing units (QPUs) based on the discrete variable model and linear optics (photonics) QPUs based on the ...

On the Teleportation of Discrete Variable Qubits Via Continuous Variable Lossy Channels [PDF]

open access: yes, 2022
The Continuous-Variable (CV) quantum state of light allows for the teleportation of a Discrete-Variable (DV) photonic qubit. Such an operation is useful in the realm of hybrid quantum networks.

Continuous-variable quantum repeater based on quantum scissors and mode multiplexing

open access: yesPhysical Review Research, 2020
Quantum repeaters are indispensable for high-rate, long-distance quantum communications. The vision of a future quantum internet strongly hinges on realizing quantum repeaters in practice.

Hierarchy of continuous-variable quantum resource theories

open access: yesNew Journal of Physics, 2021
Connections between the resource theories of coherence and purity (or non-uniformity) are well known for discrete-variable, finite-dimensional, quantum systems.

Optimal tests for continuous-variable quantum teleportation and photodetectors

open access: yesPhysical Review Research, 2022
Quantum teleportation is a primitive in several important applications, including quantum communication, quantum computation, error correction, and quantum networks. In this paper, we propose an optimal test for the performance of continuous-variable (CV)

Flow conditions for continuous variable measurement-based quantum computing [PDF]

open access: yesQuantum, 2023
In measurement-based quantum computing (MBQC), computation is carried out by a sequence of measurements and corrections on an entangled state. Flow, and related concepts, are powerful techniques for characterising the dependence of the corrections on ...
