Matrix-product-state approach for qubits-waveguide systems in real space
Shimpei Goto
We present a matrix-product-state-based numerical approach for simulating systems composed of several qubits and a common one-dimensional waveguide. In the presented approach, the…
Labeling eigenstates of qubit-cavity systems based on the continuity of qubit occupancy: Detecting resonances to higher excited qubit states
Shimpei Goto, Kazuki Koshino
We propose a new method for labeling the eigenstates of qubit-cavity systems based on the continuity of the qubit occupancy. The labeled eigenstates give a rough estimate of the ev…
Efficient numerical approach for the simulations of high-power dispersive readout with time-dependent unitary transformation
Shimpei Goto, Kazuki Koshino
We develop an efficient numerical approach for simulating the high-power dispersive readout in circuit quantum electrodynamics. In the numerical simulations of the high-power reado…
Evaluating thermal expectation values by almost ideal sampling with Trotter gates
Shimpei Goto, Ryui Kaneko, Ippei Danshita
We investigate the sampling efficiency for the simulations of quantum many-body systems at finite temperatures when initial sampling states are generated by applying Trotter gates…
Minimally entangled typical thermal states algorithm with Trotter gates
Shimpei Goto, Ippei Danshita
We improve the efficiency of the minimally entangled typical thermal states (METTS) algorithm without breaking the Abelian symmetries. By adding the operation of Trotter gates that…
