When <jats:italic>V<\/jats:italic><jats:sub><jats:italic>ab<\/jats:italic><\/jats:sub>(<jats:italic>N<\/jats:italic>) is difficult to determine, an Heisenberg-Rabi time dependent quantum exchange process must be triggered through the bus to capture the secular oscillation frequency \u03a9<jats:sub><jats:italic>ab<\/jats:italic><\/jats:sub>(<jats:italic>N<\/jats:italic>) between those states. Two different linear and \"Equation missing\" regimes are demonstrated for \u03a9<jats:sub><jats:italic>ab<\/jats:italic><\/jats:sub>(<jats:italic>N<\/jats:italic>) as a function of N. When the initial preparation is replaced by coupling of the quantum bus to semi-infinite electrodes, the resulting quantum transduction process is not faithfully following the \u03a9<jats:sub><jats:italic>ab<\/jats:italic><\/jats:sub>(<jats:italic>N<\/jats:italic>) variations. Because of the electronic transparency normalisation to unity and of the low pass filter character of this transduction, large \u03a9<jats:sub><jats:italic>ab<\/jats:italic><\/jats:sub>(<jats:italic>N<\/jats:italic>) cannot be captured by the tunnel junction. The broadly used concept of electrical contact between a metallic nanopad and a molecular device must be better described as a quantum transduction process. At small coupling and when <jats:italic>N<\/jats:italic> is small enough not to compensate for this small coupling, an <jats:italic>N<\/jats:italic><jats:sup>2<\/jats:sup> power law is preserved for \u03a9<jats:sub><jats:italic>ab<\/jats:italic><\/jats:sub>(<jats:italic>N<\/jats:italic>) and for <jats:italic>V<\/jats:italic><jats:sub><jats:italic>ab<\/jats:italic><\/jats:sub>(<jats:italic>N<\/jats:italic>).<\/jats:p>","DOI":"10.1038\/srep30198","type":"journal-article","created":{"date-parts":[[2016,7,25]],"date-time":"2016-07-25T09:19:18Z","timestamp":1469438358000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Parallel Quantum Circuit in a Tunnel Junction"],"prefix":"10.1038","volume":"6","author":[{"given":"Omid","family":"Faizy Namarvar","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ghassen","family":"Dridi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Joachim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2016,7,25]]},"reference":[{"key":"BFsrep30198_CR1","first-page":"20","volume":"L1149","author":"C Joachim","year":"1987","unstructured":"Joachim, C.
