Chemical profiles of the oxides on tantalum in state of the art superconducting circuits
Russell A. McLellan, Aveek Dutta, Chenyu Zhou +23
Over the past decades, superconducting qubits have emerged as one of the leading hardware platforms for realizing a quantum processor. Consequently, researchers have made significa…
Observation of an environmentally insensitive solid state spin defect in diamond
Brendon C. Rose, Ding Huang, Zi-Huai Zhang +9
Engineering coherent systems is a central goal of quantum science. Color centers in diamond are a promising approach, with the potential to combine the coherence of atoms with the…
Annealing shallow Si/SiO interface traps in electron-beam irradiated high-mobility metal-oxide-silicon transistors
Jin-Sung Kim, Alexei M. Tyryshkin, Stephen A. Lyon
Electron-beam (e-beam) lithography is commonly used in fabricating metal-oxide-silicon (MOS) quantum devices but creates defects at the Si/SiO interface. Here we show that a fo…
Decoherence mechanisms of 209Bi donor electron spins in isotopically pure 28Si
Gary Wolfowicz, Stephanie Simmons, Alexei M. Tyryshkin +8
Bismuth (209Bi) is the deepest Group V donor in silicon and possesses the most extreme characteristics such as a 9/2 nuclear spin and a 1.5 GHz hyperfine coupling. These lead to se…
Coherent state transfer between an electron- and nuclear spin in 15N@C60
Richard M. Brown, Alexei M. Tyryshkin, Kyriakos Porfyrakis +6
Electron spin qubits in molecular systems offer high reproducibility and the ability to self assemble into larger architectures. However, interactions between neighbouring qubits a…
Electron Paramagnetic Resonance of Boron Acceptors in Isotopically Purified Silicon
H. Tezuka, A. R. Stegner, A. M. Tyryshkin +5
The electron paramagnetic resonance (EPR) linewidths of B acceptors in Si are found to reduce dramatically in isotopically purified 28Si single crystals. Moreover, extremely narrow…
