Analysis of shape change of droplet in dipolar Bose-Hubbard model
Kazuhiro Tamura, Shohei Watabe, Tetsuro Nikuni
The long-range and anisotropic nature of the dipolar interaction provides the so-called supersolid phases in Bose-Einstein condensates (BECs) in an optical lattice. However, in a c…
Calculation of Gibbs partition function with imaginary time evolution on near-term quantum computers
Keisuke Matsumoto, Yuta Shingu, Suguru Endo +5
The Gibbs partition function is an important quantity in describing statistical properties of a system in thermodynamic equilibrium. There are several proposals to calculate the pa…
Efficient criteria of quantumness for a large system of qubits
Shohei Watabe, Michael Zach Serikow, Shiro Kawabata +1
In order to model and evaluate large-scale quantum systems, e.g. quantum computer and quantum annealer, it is necessary to quantify the ``quantumness" of such systems. In this pape…
Variational secure cloud quantum computing
Yuta Shingu, Yuki Takeuchi, Suguru Endo +5
Variational quantum algorithms (VQAs) have been considered to be useful applications of noisy intermediate-scale quantum (NISQ) devices. Typically, in the VQAs, a parametrized ansa…
Propagation of phase-imprinted solitons from superfluid core to Mott-insulator shell and superfluid shell
Yuma Watanabe, Shohei Watabe, Tetsuro Nikuni
We study phase-imprinted solitons of ultracold bosons in an optical lattice with a harmonic trap, which shows the superfluid (SF) and Mott-insulator (MI) shell structures. The earl…
