Charging by Quantum Measurement

Physical Review Applied, 2023
We propose a quantum charging scheme fueled by measurements on ancillary qubits serving as disposable chargers. A stream of identical qubits are sequentially coupled to a quantum battery of $N+1$ levels and measured by projective operations after joint unitary evolutions of optimized intervals.

Measurement of the Charged-Pion Polarizability [PDF]

Physical Review Letters, 2015
The COMPASS collaboration at CERN has investigated pion Compton scattering, $π^-γ\rightarrow π^-γ$, at centre-of-mass energy below 3.5 pion masses. The process is embedded in the reaction $π^-\mathrm{Ni}\rightarrowπ^-γ\;\mathrm{Ni}$, which is initiated by 190\,GeV pions impinging on a nickel target.

Charge Measurements in SwissFEL and Results of an Absolute Charge Measurement Method

, 2021
A comparative measurement campaign of the beam charge was carried out at SwissFEL using the following instruments: Faraday-Cup (FC), Wall-Current-Monitor (WCM), Integrating-Current-Transformer (Bergoz Turbo-ICT-2) and the reference cavity of the Beam-Position-Monitor (BPM).

Decay of Electric Charge on Corona Charged Polyethylene [PDF]

, 2007
In this paper, the surface potential decay of corona-charged low density polyethylene (LDPE) films has been investigated. It has been found that for the same sample thickness the faster decay occurs in the sample with a higher charging voltage.

Quantum measurement in charge representation [PDF]

Physical Review B, 2004
Counting statistics of charge transfers in a point contact interacting with an arbitrary quantum system is studied. The theory for the charge specific density matrix is developed, allowing the evaluation of the probability of the outcome of any joint measurement of the state of the quantum system and the transferred charge.

A measurement of the kaon charge radius [PDF]

Physics Letters B, 1986
The negative kaon electromagnetic form factor has been measured in the space-like q2 range 0.015-0.10 (GeV/c)2 by the direct scattering of 250 GeV kaons from electrons at the CERN SPS. It is found that the kaon mean square charge radius = 0.34 +/- 0.05 fm2.

Research on antenna for detecting the corona discharge of transmission line

The Journal of Engineering, 2019
Detection of corona discharge of the transmission line can reflect its health status and provide warning information for maintenance. Some existing detection methods are flawed and cannot be used widely.
