High-fidelity geometric quantum gates exceeding 99.9% in germanium quantum dots
Nature CommunicationsAchieving high-fidelity and robust qubit manipulations is a crucial requirement for realizing fault-tolerant quantum computation. Here, we demonstrate a single-hole spin qubit in a germanium quantum dot and characterize its control fidelity using gate ...

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

2024 IEEE 65th Annual Symposium on Foundations of Computer Science (FOCS)Many problems in linear algebra -- such as those arising from non-Hermitian physics and differential equations -- can be solved on a quantum computer by processing eigenvalues of the non-normal input matrices. However, the existing Quantum Singular Value Transformation (QSVT) framework is ill-suited to this task, as eigenvalues and singular values are ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Quantum-information processing with circuit quantum electrodynamics [PDF]
Physical Review A, 2007 We theoretically study single and two-qubit dynamics in the circuit QED architecture. We focus on the current experimental design [Wallraff et al., Nature 431, 162 (2004); Schuster et al., Nature 445, 515 (2007)] in which superconducting charge qubits are capacitively coupled to a single high-Q superconducting coplanar resonator.

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Realization of reliable solid-state quantum memory for photonic polarization-qubit
, 2012 Faithfully storing an unknown quantum light state is essential to advanced quantum communication and distributed quantum computation applications. The required quantum memory must have high fidelity to improve the performance of a quantum network.

Analysis of a Quantum Error Correcting Code using Quantum Process Calculus [PDF]
Electronic Proceedings in Theoretical Computer Science, 2012 We describe the use of quantum process calculus to describe and analyze quantum communication protocols, following the successful field of formal methods from classical computer science. The key idea is to define two systems, one modelling a protocol and

Measuring the degree of unitarity for any quantum process
, 2014 Quantum processes can be divided into two categories: unitary and non-unitary ones. For a given quantum process, we can define a \textit{degree of the unitarity (DU)} of this process to be the fidelity between it and its closest unitary one.
