Sufficient condition for the mode mismatch of single photons for scalability of the boson-sampling computer

V. S. Shchesnovich
2014 Physical Review A. Atomic, Molecular, and Optical Physics  
It samples the probability distribution at the output of linear unitary optical network, with indistinguishable single photons at the input.  ...  For scalability of a realistic boson sampler with current technology it is necessary to know the effect of the photon mode mismatch on its operation.  ...  Whereas the universal quantum computer targets the NP decision problems, widely believed to be classically hard, such as factoring large integers [6, 7] , the BS computer just samples the output probability  ...

Calibration for frequency-dependent mismatches in bandpass sampling TIADCs

Nan Li, Xiangyu Liu, Husheng Liu, Yinan Wang
2017 IEICE Electronics Express  
Bandpass sampling (BPS) is a widely used technique where one samples a bandpass-filtered signal at a sampling rate below its Nyquist rate (twice the upper cutoff frequency).  ...  The principle of mismatches compensation is to reconstruct the mismatches-induced spurious components and subtract them from the original TIADC's output.  ...  The state-of-the-art literatures shed much light on the mitigation of mismatches in lowpass sampling (LPS) TIADCs [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12] .  ...

Effects of basis-mismatch in compressive sampling of continuous sinusoidal signals

Daniel H. Chae, Parastoo Sadeghi, Rodney A. Kennedy
2010 2010 2nd International Conference on Future Computer and Communication  
In this paper, the degradation due to this basis mismatch is investigated and a way to minimize the effects of basis mismatch in compressive sampling of continuous sinusoidal signals is discussed.  ...  The theory of compressive sampling (or compressed sensing) is very attractive in that it is possible to reconstruct some signals with a sub-Nyquist sampling rate provided that they are sparse in some basis  ...  BASIS MISMATCH IN COMPRESSIVE SAMPLING Mismatch between the signal and reconstruction basis domains is very common, but the effects of such mismatch is not studied well in the literature.  ...

Mismatching Removal for Feature-Point Matching Based on Triangular Topology Probability Sampling Consensus

Zaixing He, Chentao Shen, Quanyou Wang, Xinyue Zhao, Huilong Jiang
2022 Remote Sensing  
However, mismatching is inevitable, and it needs to be removed. It is difficult for existing methods to remove a high ratio of mismatches.  ...  To address this issue, a robust method, called triangular topology probability sampling consensus (TSAC), is proposed, which combines the topology network and resampling methods.  ...  We propose a new sampling method-probability sampling consensus-which weights the probability calculated above to the random process of the RANSAC so that the mismatches can be detected and removed.  ...
