Molecular Qubits in a Sentence

What is/are Molecular Qubits?

Molecular Qubits - Such complexes, in particular the case of [Yb(trensal)] complex, have been proposed as molecular qubits due to their spin dynamics properties. ^[1] Photogenerated entangled electron spin pairs provide a versatile source of molecular qubits. ^[2] The soft-donor, eight-coordinate ligand shell combined with the fully delocalised ground state provides a highly rigid and covalent environment that will nurture long spin relaxation times in vanadyl-based molecular qubits. ^[3] With the power of chemistry for inexpensive synthesis of tailored systems, molecular qubits are attractive candidates for quantum computing. ^[4] This finding offers guidance for the design of spectrally addressable molecular qubits. ^[5] However, a poor understanding of relaxation mechanisms limits the exploitation of nuclear-spin molecular qubits. ^[6] The scalability and stability of molecular qubits deposited on surfaces is a crucial step for incorporating them into upcoming electronic devices. ^[7] Then we study the dependence of spin dephasing over the magnetic dilution for a crystal of Vanadyl-based molecular qubits. ^[8] Spin-based molecular qubits are promising because they unify atomicscale spatial precision with structural customization for systems integration (4). ^[9] The lack of a microscopic understanding about the role of vibrations in spin relaxation strongly undermines the possibility of chemically designing better-performing molecular qubits. ^[10] This new hybrid architecture could be employed for local investigation of static and dynamic spin properties and as molecular qubits for spintronic applications. ^[11] This technique has been also applied to the archetypical single-molecule magnet Mn12 to unambiguously characterise its Spin Hamiltonian as well as to portray the entanglement between molecular qubits in (Cr7Ni)2. ^[12] Here, we present a comprehensive study of the spin dynamics of a crystal of Vanadyl-based molecular qubits by means of first-order perturbation theory and first-principles calculations. ^[13] Achieving strong interactions and entanglement between molecular qubits remains an outstanding challenge. ^[14]
