Observable Geometry for Effective Quantum Circuits
Huan-Hsin Tseng, Hsin-Yi Lin, Samuel Yen-Chi Chen +3
We study redundancy and effectiveness of Variational Quantum Circuits via algebraic and geometric views of Lie groups. Considering unitary transformations acting on Hermitian obser…
An Improved Method for Quantum Matrix Multiplication
Nhat A. Nghiem, Tzu-Chieh Wei
Following the celebrated quantum algorithm for solving linear equations (so-called HHL algorithm), Childs, Kothari and Somma [SIAM Journal on Computing, {\bf 46}: 1920, (2017)] pro…
Symmetry-enriched topological order from partially gauging symmetry-protected topologically ordered states assisted by measurements
Yabo Li, Hiroki Sukeno, Aswin Parayil Mana +2
Symmetry protected topological phases exhibit nontrivial short-ranged entanglement protected by symmetry and cannot be adiabatically connected to trivial product states while prese…
Quantum simulation of lattice gauge theories via deterministic duality transformations assisted by measurements
Hiroki Sukeno, Tzu-Chieh Wei
Quantum simulation is one of the major applications of quantum devices. In the noisy intermediate-scale quantum era, however, the general quantum simulation is not yet feasible, su…
Tensor Network Methods for Extracting CFT Data from Fixed-Point Tensors and Defect Coarse Graining
Wenhan Guo, Tzu-Chieh Wei
We present a comprehensive study on the extraction of CFT data using tensor network methods, specially, from the fixed-point tensor of the linearized tensor renormalization group (…
Learning marginals suffices!
Nengkun Yu, Tzu-Chieh Wei
Beyond computer science, quantum complexity theory can potentially revolutionize multiple branches of physics, ranging from quantum many-body systems to quantum field theory. In th…
