Controlling the Inhomogeneous Broadening and Impedance Matching of a Spin Ensemble
Mathieu Couillard, Debdip Guchait, Hiroki Takahashi +1
The authors use a magnetic field gradient generated by an anti‑Helmholtz coil to shape the spectral distribution of a spin ensemble and achieve impedance matching to a transmission…
Channel-agnostic finite-temperature phase estimation averaged over variable grids: reconstruction of Green's function for dynamical mean-field theory
Taichi Kosugi, Hirofumi Nishi, Keito Kasebayashi +2
For treating correlated electronic systems on quantum computers, we propose a quantum-classical hybrid scheme for dynamical mean-field theory (DMFT). In the quantum part of the sch…
Error-corrected phase estimation averaged over variable grids on a trapped-ion quantum computer: hyperacuity spectra of a CO molecule adsorbed onto -FeC
Taichi Kosugi, Hirofumi Nishi, Keito Kasebayashi +2
Quantum phase estimation (QPE) is an underlying technology for extracting the excitation spectra of many-electron systems, yet its practical use on current hardware is hindered by…
Rate-fidelity trade-off in cavity-based remote entanglement generation
Kazufumi Tanji, Hiroki Takahashi, Wojciech Roga +1
The qubit scalability imposes a paramount challenge in the field of quantum computing. Photonic interconnects between distinct quantum computing modules provide a solution to deal…
