The magnetic energy level spectrum of these molecules meets then all conditions needed to realize a universal CNOT quantum gate. A proposal to realize a SWAP gate within the same molecule is also discussed. Electronic paramagnetic resonance experiments confirm that CNOT and SWAP transitions are not forbidden.5 p.application/pdfeng(c) American Physical Society, 2011NanotecnologiaOrdinadors quànticsNanotechnologyQuantum computersinfo:eu-repo/semantics/article5989872012-03-16info:eu-repo/semantics/openAccess
