Quantum computation at the edge of chaos
Tomohiro Hashizume, Zhengjun Wang, Frank Schlawin +1
A key challenge in classical machine learning is to mitigate overparameterization by selecting sparse solutions. We translate this concept to the quantum domain, introducing quantu…
Sparse Optimization of Two-Dimensional Terahertz Spectroscopy
Zhengjun Wang, Hongju Da, Ankit S. Disa +3
Two-dimensional terahertz spectroscopy (2DTS) is a low-frequency analogue of two-dimensional optical spectroscopy that is rapidly maturing as a probe of a wide variety of condensed…
Beating signals in CdSe quantum dots measured by low-temperature 2D spectroscopy
Zhengjun Wang, Albin Hedse, Edoardo Amarotti +5
Advances in ultrafast spectroscopy can provide access to dynamics involving nontrivial quantum correlations and their evolutions. In coherent 2D spectroscopy, the oscillatory time…
Compressed Sensing for Reconstructing Coherent Multidimensional Spectra
Zhengjun Wang, Shiwen Lei, Khadga Jung Karki +2
We apply two sparse reconstruction techniques, the least absolute shrinkage and selection operator (LASSO) and the sparse exponential mode analysis (SEMA), to two-dimensional (2D)…
