Stabilizer Statistical Mechanics: A Framework for Efficient Quantification and Classification of Magic States
William E. Salazar, Gaurav Saxena, Jack S. Baker +2
The partition function is statistical mechanics' answer to an exponentially large spectrum, distilling it into a single analytic object whose temperature dependence resolves the fu…
Continuous-variable state moments from randomized homodyne and heterodyne measurements
Michael Tsesmelis, Moritz Straeter, Leong-Chuan Kwek
Continuous-variable (CV) quantum states are naturally characterized by their moments, defined as expectation values of products of single- or multimode ladder operators. Many CV Ha…
Pauli Weight Hamiltonian Term Selection for Optimized Machine Learning Based Quantum Error Mitigation
Fadhil Fatih Shiddiq, Darell Timothy Tarigan, Hadyan Luthfan Prihadi +4
Machine learning provides a scalable solution for quantum error mitigation. However, the selection of appropriate Pauli strings for inclusion in training data remains a challenge.…
Detecting entanglement of non-Gaussian continuous-variable states from single-copy homodyne measurements
Moritz Straeter, Michael Tsesmelis, Leong-Chuan Kwek
The entanglement of Gaussian continuous-variable (CV) states is fully determined by the state's second moments. In contrast, some entangled non-Gaussian states evade every second-m…
Enhanced Density Fluctuations Near a Disordered Chiral Topological Transition
Hai-Tao Ding, Sen Mu, Leong-Chuan Kwek +2
The universal statistics of density fluctuations of localized quantum states may offer unprecedented opportunities to probe and understand quantum transport in connection with dime…
Photonic-Implemented Efficient Deep Quantum Neural Network via Virtual-Driven Hilbert Space Expansion
Haoran Ma, Huihui Zhu, Zichao Zhao +10
The growing computational demands of classical neural networks have intensified the search for energy-efficient and powerful computational alternatives. Quantum neural networks (QN…
