Analysis of Parameterized Quantum Circuits: on The Connection Between Expressibility and Types of Quantum Gates
Yu Liu, Kentaro Baba, Kazuya Kaneko +3
Expressibility is a crucial factor of a Parameterized Quantum Circuit (PQC). In the context of Variational Quantum Algorithms (VQA) based Quantum Machine Learning (QML), a QML mode…
Low-dimensional antiferromagnetic fluctuations in the heavy-fermion paramagnetic ladder UTe
W. Knafo, G. Knebel, P. Steffens +7
Inelastic-neutron-scattering measurements were performed on a single crystal of the heavy-fermion paramagnet UTe above its superconducting temperature. We confirm the presence…
Linear Regression by Quantum Amplitude Estimation and its Extension to Convex Optimization
Kazuya Kaneko, Koichi Miyamoto, Naoyuki Takeda +1
Linear regression is a basic and widely-used methodology in data analysis. It is known that some quantum algorithms efficiently perform least squares linear regression of an expone…
Characterizing symmetry-protected thermal equilibrium by work extraction
Yosuke Mitsuhashi, Kazuya Kaneko, Takahiro Sagawa
The second law of thermodynamics states that work cannot be extracted from thermal equilibrium, whose quantum formulation is known as complete passivity; A state is called complete…
Eigenstate Fluctuation Theorem in the Short and Long Time Regimes
Eiki Iyoda, Kazuya Kaneko, Takahiro Sagawa
The canonical ensemble plays a crucial role in statistical mechanics in and out of equilibrium. For example, the standard derivation of the fluctuation theorem relies on the assump…
Quantum Speedup of Monte Carlo Integration with respect to the Number of Dimensions and its Application to Finance
Kazuya Kaneko, Koichi Miyamoto, Naoyuki Takeda +1
Monte Carlo integration using quantum computers has been widely investigated, including applications to concrete problems. It is known that quantum algorithms based on quantum ampl…
