Confidence polytopes for quantum process tomography
New Journal of Physics, 2021 In the present work, we propose a generalization of the confidence polytopes approach for quantum state tomography (QST) to the case of quantum process tomography (QPT).

Quantum model for supercontinuum generation process
Scientific Reports, 2022 A quantum theory is established for the propagation of electromagnetic waves in highly nonlinear dispersive optical fibers. By applying the method recently presented dispersion terms and retarded response of the medium are included for the propagation of

Quantum Stochastic Processes [PDF]
, 1985 Let ℬ be *-algebra with identity (usually it wil be a C*- or a W*-algebra). A quantum stochastic process over ℬ indexed by ℝ is defined by a triple {A, (jt)t∈ℝ, φ} where A is a *-algebra with identity. jt : ℬ ↪A is an embedding (t∈ℝ). φ is a State on A.

Application of a Quantum-Well Silicon NMOS Transistor as a Folding Amplifier Frequency Multiplier
IEEE Journal of the Electron Devices Society, 2017 This paper reports on the use of a single quantum well (QW) silicon NMOS transistor to generate a folded current-voltage transfer function that enables frequency doubling and tripling. The QW NMOS device is fabricated entirely on an industrially standard

Compressed sensing quantum process tomography for superconducting quantum gates
, 2014 We apply the method of compressed sensing (CS) quantum process tomography (QPT) to characterize quantum gates based on superconducting Xmon and phase qubits. Using experimental data for a two-qubit controlled-Z gate, we obtain an estimate for the process

Limit theorems for open quantum random walks [PDF]
, 2012 We consider the limit distributions of open quantum random walks on one-dimensional lattice space. We introduce a dual process to the original quantum walk process, which is quite similar to the relation of Schr\"odinger-Heisenberg representation in ...

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
