Unparalleled selectivity and electronic structure of heterometallic [LnLn′Ln] molecules as 3-qubit quantum gates

Abstract

Heterometallic lanthanide [LnLn’] coordination complexes accessible thermodynamically are very scarce because the metals of this series have very similar chemical behaviour. Trinuclear systems of this category are virtually non-existent. A...

An exchange coupled meso–meso linked vanadyl porphyrin dimer for quantum information processing

“…Various molecular systems have been investigated and proposed as multi-qubit platforms. [9][10][11][12][13] Here, addressability has been achieved through two different molecular design strategies: (i) inclusion of paramagnetic centers with different electronic and magnetic properties (e.g., two different Landé factors, g); 9,10,13,14 (ii) inclusion of the same paramagnetic moiety characterized by signicant magnetic anisotropy and different orientation in space. 11 Most of these systems were also designed to minimize the hyperne interactions detrimental to T m .…”

Using internal strain and mass to modulate Dy⋯Dy coupling and relaxation of magnetization in heterobimetallic metallofullerenes DyM2N@C80and Dy2MN@C80(M = Sc, Y, La, Lu)

“…22–31 Such a precise composition control in a virtually identical chemical environment is quite unique and rarely available for heterometallic systems in lanthanide chemistry. 32–38…”

“…[22][23][24][25][26][27][28][29][30][31] Such a precise composition control in a virtually identical chemical environment is quite unique and rarely available for heterometallic systems in lanthanide chemistry. [32][33][34][35][36][37][38] In this work, we employ the M′ x M″ 3−x N@C 80 platform to study the influence of the internal strain on the static and dynamic magnetic properties of Dy-containing nitride clusterfullerenes. The use of external stimuli to modulate the properties of single molecule magnets has attracted significant attention as it opens the way for multifunctional magnetic systems.…”

Long Aliphatic Chain Derivatives of Trigonal Lanthanide Complexes

“…Lanthanide (Ln) based materials are central to various research fields such as MRI contrast agents, [1][2][3] anti-counterfeiting, [4][5] luminescent thermometers, [6][7][8][9] single molecule magnets (SMMs) [10][11][12][13][14] and quantum information processing [15][16][17][18][19] . The intense interest in Ln based complexes is due to the special properties of the 4f electrons in Ln III ions.…”
