Quantum Algorithms for Josephson Networks [PDF]

open access: greenPhysical Review Letters, 2001
We analyze possible implementations of quantum algorithms in a system of (macroscopic) Josephson charge qubits. System layout and parameters to realize the Deutsch algorithm with up to three qubits are provided. Special attention is paid to the necessity of entangled states in the various implementations.

A new non-entangled quantum secret sharing protocol among different nodes in further quantum networks

open access: yesFrontiers in Physics, 2022
As an important branch of quantum secure multi-party computation, quantum secret sharing (QSS) can distribute secret information among dishonest network nodes without revealing the secrets.

A quantum access network [PDF]

open access: yesNature, 2013
The theoretically proven security of quantum key distribution (QKD) could revolutionise how information exchange is protected in the future. Several field tests of QKD have proven it to be a reliable technology for cryptographic key exchange and have demonstrated nodal networks of point-to-point links.

Cyclic networks of quantum gates. [PDF]

open access: green, 2002
In this article initial steps in an analysis of cyclic networks of quantum logic gates is given. Cyclic networks are those in which the qubit lines are loops.

Policies for elementary links in a quantum network [PDF]

open access: yesQuantum, 2020
Distributing entanglement over long distances is one of the central tasks in quantum networks. An important problem, especially for near-term quantum networks, is to develop optimal entanglement distribution protocols that take into account the ...

Optimized Quantum Networks

open access: yesQuantum, 2023
The topology of classical networks is determined by physical links between nodes, and after a network request the links are used to establish the desired connections. Quantum networks offer the possibility to generate different kinds of entanglement prior to network requests, which can substitute links and allow one to fulfill multiple network requests

Experimental Demonstration of Secure Relay in Quantum Secure Direct Communication Network

open access: yesEntropy, 2023
Quantum secure direct communication (QSDC) offers a practical way to realize a quantum network which can transmit information securely and reliably. Practical quantum networks are hindered by the unavailability of quantum relays.

Entangled-Based Quantum Wavelength-Division-Multiplexing and Multiple-Access Networks

open access: yesEntropy, 2023
This paper investigates the mathematical model of the quantum wavelength-division-multiplexing (WDM) network based on the entanglement distribution with the least required wavelengths and passive devices.
