Teleportation capability, distillability, and nonlocality on three-qubit states [PDF]

open access: yes, 2007
In this paper, we consider teleportation capability, distillability, and nonlocality on three-qubit states. In order to investigate some relations among them, we first find the explicit formulas of the quantities about the maximal teleportation fidelity ...

Characterization and tomography of a hidden qubit [PDF]

open access: yesPhys. Rev. X 11, 041032 (2021), 2020
In circuit-based quantum computing, the available gate set typically consists of single-qubit gates acting on each individual qubit and at least one entangling gate between pairs of qubits. In certain physical architectures, however, some qubits may be 'hidden' and lacking direct addressability through dedicated control and readout lines, for instance ...

Quantum Logic Locking for Security

open access: yesJ, 2023
Having access to a unique quantum circuit that one wants to protect against use by others is a very likely scenario in industrial computing. However, currently, users rely on classical computer security schemes, which have known shortcomings.

Topological Qubits as Carriers of Quantum Information in Optics

open access: yesApplied Sciences, 2019
Winding number is a topologically significant quantity that has found valuable applications in various areas of mathematical physics. Here, topological qubits are shown capable of formation from winding number superpositions and so of being used in the ...

Synchronizing two superconducting qubits through a dissipating resonator [PDF]

open access: yesEntropy 23, 998 (2021), 2021
A system consisting of two qubits and a resonator is considered in the presence of different sources of noise, bringing to light the possibility for making the two qubits evolve in a synchronized way. A direct qubit-qubit interaction turns out to be a crucial ingredient as well as dissipation processes involving the resonator.

A Pair of Coupled Waveguides as a Classical Analogue for a Solid-State Qubit

open access: yesSensors, 2022
We have determined conditions when a pair of coupled waveguides, a common element for integrated room-temperature photonics, can act as a qubit based on a system with a double-well potential.
