Iterative quantum amplitude estimation [PDF]
npj Quantum Information, 2019 We introduce a variant of Quantum Amplitude Estimation (QAE), called Iterative QAE (IQAE), which does not rely on Quantum Phase Estimation (QPE) but is only based on Grover’s Algorithm, which reduces the required number of qubits and gates.

Amplitude dependence of image quality in atomically-resolved bimodal atomic microscopy [PDF]
, 2016 In bimodal FM-AFM, two flexural modes are excited simultaneously. The total vertical oscillation deflection range of the tip is the sum of the peak-to-peak amplitudes of both flexural modes (sum amplitude).

Experimental demonstration of a temporal pulse shaping method based on nonlinear chirp [PDF]
EPJ Web of ConferencesWe present a general temporal shaping method based on spectral phase-only modulation for ultrafast laser sources. We explain the working principle of this technique and use it experimentally to generate a ramp-shaped pulse at the output of a laser source

High-amplitude cofluctuations in cortical activity drive functional connectivity
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Despite widespread applications, the origins of functional connectivity remain elusive. Here we analyze human functional neuroimaging data. We decompose resting-state functional connectivity across time to assess the contributions of moment ...

Physics Reports, 2017 This a pedagogical introduction to scattering amplitudes in gauge theories. It proceeds from Dirac equation and Weyl fermions to the two pivot points of current developments: the recursion relations of Britto, Cachazo, Feng and Witten, and the unitarity cut method pioneered by Bern, Dixon, Dunbar and Kosower.

Large-amplitude driving of a superconducting artificial atom: Interferometry, cooling, and amplitude spectroscopy [PDF]
, 2009 Superconducting persistent-current qubits are quantum-coherent artificial atoms with multiple, tunable energy levels. In the presence of large-amplitude harmonic excitation, the qubit state can be driven through one or more of the constituent energy ...

Solving Systems of Random Quadratic Equations via Truncated Amplitude Flow [PDF]
IEEE Transactions on Information Theory, 2016 This paper presents a new algorithm, termed truncated amplitude flow (TAF), to recover an unknown vector $ {x}$ from a system of quadratic equations of the form $y_{i}=|\langle {a}_{i}, {x}\rangle |^{2}$ , where $ {a}_{i}$ ’s are given random ...
