Room-temperature test system for 162.5 MHz high-power couplers
Fundamental power couplers are crucial components for feeding radio frequency power to accelerating cavities. Couplers must be tested and conditioned on a room-temperature test stand to evaluate and potentiall...

Restricted (k, n)-threshold quantum secret sharing scheme based on local distinguishability of orthogonal multiqudit entangled states
In this work, we study a restricted (k, n)-threshold access structure. According to this structure, we construct a group of orthogonal multipartite entangled states in d-dimensional system and investigate the dis...

Improving fidelity of quantum secret sharing in noisy environments
Quantum secret sharing is a procedure for sharing a secret among a number of participants such that only certain subsets of participants can collaboratively reconstruct it. In this paper, we review a quantum ...

Quantum secret sharing using orthogonal multiqudit entangled states
In this work, we investigate the distinguishability of orthogonal multiqudit entangled states under restricted local operations and classical communication. According to these properties, we propose a quantum ...

Quantum secret sharing for a general quantum access structure
Quantum secret sharing is a procedure for sharing a secret among a number of participants such that only certain subsets of participants can collaboratively reconstruct it, which are called authorized sets. T...

Quantum secret sharing using the d-dimensional GHZ state
We propose a quantum secret sharing scheme that uses an orthogonal pair of n-qudit GHZ states and local distinguishability. In the proposed protocol, the participants use an X-basis measurement and classical comm...

A Generalized Information Theoretical Model for Quantum Secret Sharing
An information theoretical model for quantum secret sharing was introduced by H. Imai et al. (Quantum Inf. Comput. 5(1), 69–80 2005), which was analyzed by quantum information theory. In this paper, we analyze th...

Design study on medium beta superconducting half-wave resonator at IMP
A 325-MHz superconducting half-wave resonator has been designed with β = 0.51. Three shapes of the inner conductors (race track, ring shape and elliptical shape) were optimized to decrease the peak electromagneti...

Probabilistic Quantum Information Splitting Based on the Non-maximally Entangled Four-Qubit State
In this paper, we propose a scheme for quantum information splitting based on the non-maximally entangled four-qubit state in order to realize the splitting of the specific two-qubit state |ψ〉 A

Constraints in Noncommutative Chern-Simons Mechanics and Hall Effect
We study noncommutative Chern-Simons mechanics and noncommutative Hall effect by Dirac theory in this paper. The magnetic field is introduced by means of minimal coupling. We show that the constraint set will ...

Pseudo Weak Effect Algebras and Pseudo Weak D-posets
Pseudo weak effect algebras are base on an noncommutative, associative and cancellative partial addition, but in general not determined by it. Every pseudo BL-algebra gives rise to a pseudo weak effect algebra.

Path Integral Formulation for Chern-Simons Quantum Mechanics
Chern-Simons quantum mechanics is studied by using the path integral formulation. We find that the model can be decomposed into two independent oscillators when a set of new coordinate is chosen. The propagato...
