Quantum Computing for Energy Management: A Semi Non-Technical Guide for Practitioners
Jirawat Tangpanitanon
The pursuit of energy transition necessitates the coordination of several technologies, including more efficient and cost-effective distributed energy resources (DERs), smart grids…
Explainable Natural Language Processing with Matrix Product States
Jirawat Tangpanitanon, Chanatip Mangkang, Pradeep Bhadola +3
Despite empirical successes of recurrent neural networks (RNNs) in natural language processing (NLP), theoretical understanding of RNNs is still limited due to intrinsically comple…
Hybrid Quantum-Classical Algorithms for Loan Collection Optimization with Loan Loss Provisions
Jirawat Tangpanitanon, Jirawat Saiphet, Pantita Palittapongarnpim +6
Banks are required to set aside funds in their income statement, known as a loan loss provision (LLP), to account for potential loan defaults and expenses. By treating the LLP as a…
Quantum supremacy and quantum phase transitions
Supanut Thanasilp, Jirawat Tangpanitanon, Marc-Antoine Lemonde +2
Demonstrating the ability of existing quantum platforms to perform certain computational tasks intractable to classical computers represents a cornerstone in quantum computing. Des…

A crucial milestone in the field of quantum simulation and computation is to demonstrate that a quantum device can compute certain tasks that are impossible to reproduce by a class…
Many-Body Physics and Quantum Simulations with Strongly Interacting Photons
Jirawat Tangpanitanon, Dimitris G. Angelakis
Simulating quantum many-body systems on a classical computer generally requires a computational cost that grows exponential with the number of particles. This computational complex…
Quantum supremacy with analog quantum processors for material science and machine learning
Jirawat Tangpanitanon, Supanut Thanasilp, Marc-Antoine Lemonde +1
Quantum supremacy is the ability of quantum processors to outperform classical computers at certain tasks. In digital random quantum circuit approaches for supremacy, the output di…
Dynamical quantum phase transitions and non-Markovian dynamics
Thi Ha Kyaw, Victor M. Bastidas, Jirawat Tangpanitanon +2
In the context of closed quantum systems, when a system prepared in its ground state undergoes a sudden quench, the resulting Loschmidt echo can exhibit zeros, resembling the Fishe…
Strongly correlated photon transport in nonlinear photonic lattice with disorder: Probing signatures of the localization transition
Tian Feng See, V. M. Bastidas, Jirawat Tangpanitanon +1
We study the transport of few-photon states in an open disordered nonlinear photonic lattice. More specifically, we consider a waveguide quantum electrodynamics (QED) setup where p…
Discrete time crystal in globally driven interacting quantum systems without disorder
Wing Chi Yu, Jirawat Tangpanitanon, Alexander W. Glaetzle +2
Time crystals in periodically driven systems have initially been studied assuming either the ability to quench the Hamiltonian between different many-body regimes, the presence of…
