Hyperentanglement concentration of nonlocal two-photon six-qubit systems via the cross-Kerr nonlinearity

open access: yesScientific Reports, 2020
We present an efficient hyperentanglement concentration protocol (hyper-ECP) for two-photon six-qubit systems in nonlocal partially hyperentangled Bell states with unknown parameters.

Coherent control of a donor-molecule electron spin qubit in silicon

open access: yesNature Communications, 2021
Multi-donor molecules in Si provide a promising qubit platform, offering advantages over single donor qubits in terms of performance and fabrication. Here, the authors report a single qubit gate and long coherence times in a P donor molecule qubit in ...

Supersonic quantum communication

open access: yes, 2009
When locally exciting a quantum lattice model, the excitation will propagate through the lattice. The effect is responsible for a wealth of non-equilibrium phenomena, and has been exploited to transmit quantum information through spin chains.

Quantum non-Gaussianity and secure quantum communication [PDF]

open access: yesnpj Quantum Information, 2019
No-cloning theorem, a profound fundamental principle of quantum mechanics, also provides a crucial practical basis for secure quantum communication. The security of communication can be ultimately guaranteed if the output fidelity via the communication ...

Quantum Switch for the Quantum Internet: Noiseless Communications through Noisy Channels [PDF]

open access: yesIEEE Journal on Selected Areas in Communications (JSAC), 2020, 2019
Counter-intuitively, quantum mechanics enables quantum particles to propagate simultaneously among multiple space-time trajectories. Hence, a quantum information carrier can travel through different communication channels in a quantum superposition of different orders, so that the relative time-order of the communication channels becomes indefinite ...

Direct Ink Writing of Conductive Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
This review examines the use of direct ink writing (DIW) for fabricating conductive hydrogels with customizable 3D structures. It outlines the rheological requirements for successful DIW, followed by an exploration of the materials and ink formulations used to impart electronic and/or ionic conductivity to hydrogels while maintaining printability ...

Verifying the security of a continuous variable quantum communication protocol via quantum metrology

open access: yesnpj Quantum Information
Quantum mechanics offers the possibility of unconditionally secure communication between multiple remote parties. Security proofs for such protocols typically rely on bounding the capacity of the quantum channel in use.
