Rigorous noise reduction with quantum autoencoders
Wai-Keong Mok, Hui Zhang, Tobias Haug +6
Reducing noise in quantum systems is a major challenge towards the application of quantum technologies. Here, we propose and demonstrate a scheme to reduce noise using a quantum au…
Gaussian boson sampling at finite temperature
Gabriele Bressanini, Hyukjoon Kwon, M. S. Kim
Gaussian boson sampling (GBS) is a promising candidate for an experimental demonstration of quantum advantage using photons. However, sufficiently large noise might hinder a GBS im…
Limitations of probabilistic error cancellation for open dynamics beyond sampling overhead
Yue Ma, M. S. Kim
Quantum simulation of dynamics is an important goal in the NISQ era, within which quantum error mitigation may be a viable path towards modifying or eliminating the effects of nois…
Quantum operations with the time axis in a superposed direction
Seok Hyung Lie, M. S. Kim
In the quantum theory, it has been shown that one can see if a process has the time reversal symmetry by applying the matrix transposition and examining if it remains physical. How…
Efficient quantum algorithms for stabilizer entropies
Tobias Haug, Soovin Lee, M. S. Kim
Stabilizer entropies (SEs) are measures of nonstabilizerness or `magic' that quantify the degree to which a state is described by stabilizers. SEs are especially interesting due to…
Probing spectral features of quantum many-body systems with quantum simulators
Jinzhao Sun, Lucia Vilchez-Estevez, Vlatko Vedral +2
The efficient probing of spectral features is important for characterising and understanding the structure and dynamics of quantum materials. In this work, we establish a framework…
