TTNOpt: Tree tensor network package for high-rank tensor compression
Ryo Watanabe, Hidetaka Manabe, Toshiya Hikihara +1
We have developed TTNOpt, a software package that utilizes tree tensor networks (TTNs) for quantum spin systems and high-dimensional data analysis. TTNOpt provides efficient and po…
Divide-and-conquer verification method for noisy intermediate-scale quantum computation
Yuki Takeuchi, Yasuhiro Takahashi, Tomoyuki Morimae +1
Several noisy intermediate-scale quantum computations can be regarded as logarithmic-depth quantum circuits on a sparse quantum computing chip, where two-qubit gates can be directl…
Post-Hartree-Fock method in Quantum Chemistry for Quantum Computer
Yutaka Shikano, Hiroshi C. Watanabe, Ken M. Nakanishi +1
Quantum computational chemistry is a potential application of quantum computers that is expected to effectively solve several quantum-chemistry problems, particularly the electroni…
Local trade-off between information and disturbance in quantum measurements
Hiroaki Terashima
This study confirms a local trade-off between information and disturbance in quantum measurements. It is represented by the correlation between the changes in these two quantities…
Derivative of the disturbance with respect to information from quantum measurements
Hiroaki Terashima
To study the trade-off between information and disturbance, we obtain the first and second derivatives of the disturbance with respect to information for a fundamental class of qua…
Merlin-Arthur with efficient quantum Merlin and quantum supremacy for the second level of the Fourier hierarchy
Tomoyuki Morimae, Yuki Takeuchi, Harumichi Nishimura
We introduce a simple sub-universal quantum computing model, which we call the Hadamard-classical circuit with one-qubit (HC1Q) model. It consists of a classical reversible circuit…
