Efficient one-step generation of large cluster states with solid-state circuits
J. Q. You, Xiang-bin Wang, Tetsufumi Tanamoto +1
Highly entangled states called cluster states are a universal resource for measurement-based quantum computing (QC). Here we propose an efficient method for producing large cluster…
The Effect of Side Traps on Ballistic Transistor in Kondo Regime
Tetsufumi Tanamoto, Ken Uchida, Shinobu Fujita
The effect of side-traps on conductance is calculated in the range of slave-boson mean field theory, especially when there are electrodes on both sides of the conductor. This corre…
Producing cluster states in charge qubits and flux qubits
Tetsufumi Tanamoto, Yu-xi Liu, Shinobu Fujita +2
We propose a method to efficiently generate cluster states in charge qubits, both semiconducting and superconducting, as well as flux qubits. We show that highly-entangled cluster…
Robustness of Decoherence-Free States for Charge Qubits under Local Non-uniformity
Tetsufumi Tanamoto, Shinobu Fujita
We analyze the robustness of decoherence-free (DF) subspace and subsystem in charge qubits, when difference from the collective decoherence measurement condition is large in the lo…
Measurement of Two-Qubit States by a Two-Island Single Electron Transistor
Tetsufumi Tanamoto, Xuedong Hu
We solve the master equations of two charged qubits measured by a single-electron transistor (SET) consisted of two islands. We show that in the sequential tunneling regime the SET…
