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…
Double quantum dot turnstile as an electron spin entangler
Xuedong Hu, S. Das Sarma
We study the conditions for a double quantum dot system to work as a reliable electron spin entangler, and the efficiency of a beam splitter as a detector for the resulting entangl…
Effects of dynamical phases in Shor's factoring algorithm with operational delays
L. F. Wei, Xiao Li, Xuedong Hu +1
Ideal quantum algorithms usually assume that quantum computing is performed continuously by a sequence of unitary transformations. However, there always exist idle finite time inte…
Spin swap gate in the presence of qubit inhomogeneity in a double quantum dot
Xuedong Hu, S. Das Sarma
We study theoretically the effects of qubit inhomogeneity on the quantum logic gate of qubit swap, which is an integral part of the operations of a quantum computer. Our focus here…
