Nov 2, 2021 · Here we propose an electrical nuclear manipulation called nuclear electric resonance which can on the one hand address the single nuclear qubit, and on the other keep the long coherence time. Applying this, we construct universal quantum gates with external electric field.

Could the nuclear quadrupole interaction (Sect. 3.3) be the interaction that drives the observed nuclear spin transitions? In principle, the gates produce inhomogeneous electric fields, and the corresponding electric field gradient (EFG) could be used to induce transitions between nuclear spin states via the quadrupole interaction. However, the dir...
If the driving mechanism is indeed electric in origin, the transitions would not need to be driven via the antenna. In fact, the antenna is designed to minimize electric fields, and therefore driving via a gate instead should produce significantly stronger electric fields, which would amplify the drive strengths. This hypothesis has been tested by ...
Modulation of the \\(Q_{xx}\\), \\(Q_{yy}\\) or \\(Q_{xy}\\) quadrupole terms allows driving of \\(\\Delta m_I = \\pm 2\\) transitions (Fig. 6.7A). The resonance frequency of a transition \\( \\left| {m_I - 2} \\right\\rangle \\leftrightarrow \\left| {m_I} \\right\\rangle \\) is equal to the sum of the two corresponding \\(\\Delta m_I = \\pm 1\\)transition frequencies Al...
The relation between the Rabi frequency \\(f_\\mathrm {Rabi}\\) and drive strength provides information on the transition type. For a first-order process, \\(f_\\mathrm {Rabi}\\) scales linearly with the drive amplitude \\(V_\\mathrm {RF}^\\mathrm {gate}\\). A second-order process, such as a two-photon process, will instead have a quadratic dependence of \\(f...

A happy accident in the laboratory has led to a breakthrough discovery that not only solved a problem that stood for more than half a century, but has major implications for the development of quantum computers and sensors.In a study published ...
Nov 9, 2023 · Abstract. Nuclear electric resonance (NER) spectroscopy is currently experiencing a revival as a tool for nuclear spin-based quantum computing. Compared to magnetic or electric fields, local electron density fluctuations caused by changes in the atomic environment provide a much higher spatial resolution for the addressing of nuclear spins in ...
