Molecular spins are promising building blocks of future quantum technologies thanks to the unparalleled flexibility provided by chemistry, which allows design complex structures targeted for specific applications. However, their weak interaction with external stimuli makes it difficult access state at single-molecule level, a fundamental tool use, example, in computing and sensing. Here, an innovative solution exploiting interplay between chirality magnetism using chirality-induced spin...
The recent discovery of single-ion magnets with magnetic hysteresis above liquid-nitrogen temperatures placed these compounds among the best candidates to realize high-density storage devices. Starting from a prototypical dysprosocenium molecule, showing up 60 K, we derive here general recipe design high-blocking-temperature rare-earth magnets. complex relaxation is unraveled by combining magnetization and nuclear resonance measurements inelastic neutron scattering experiments ab initio...
We show that molecular nanomagnets have a potential advantage in the crucial rush toward quantum computers. Indeed, sizable number of accessible low-energy states these systems can be exploited to define qubits with embedded error correction. derive scheme achieve this objective and corresponding sequence microwave/radiofrequency pulses needed for correction procedure. The effectiveness our approach is shown already minimal S = 3/2 unit an existing molecule, scaling larger spin...
We show that a [Er-Ce-Er] molecular trinuclear coordination compound is promising platform to implement the three-qubit quantum error correction code protecting against pure dephasing, most important in magnetic molecules. characterize it by preparing [Lu-Ce-Lu] and [Er-La-Er] analogues, which contain only one of two types qubit, combining magnetometry, low-temperature specific heat electron paramagnetic resonance measurements on both elementary constituents trimer. Using resulting...
We discuss a cost-effective approach to understand magnetic relaxation in the new generation of rare-earth single-molecule magnets. It combines ab initio calculations crystal field parameters, magneto-elastic coupling with local modes, and phonon density states fitting only three microscopic parameters. Although much less demanding than fully approach, method gives important physical insights into origin observed relaxation. By applying it high-anisotropy compounds very different relaxation,...
Thanks to the large number of levels which can be coherently manipulated, molecular spin systems constitute a very promising platform for quantum computing. Indeed, they embed error correction within single objects, thus greatly simplifying its actual realization in short term. We consider recent proposal, exploits qudit encode protected unit, and is tailored fight pure dephasing. Here we compare implementation this code on different molecules, provided by either an electronic or nuclear (S,...
It is well assessed that the charge transport through a chiral potential barrier can result in spin-polarized charges. The possibility of driving this process visible photons holds tremendous for several aspects quantum information science, e.g., optical control and readout qubits. In context, direct observation phenomenon via spin-sensitive spectroscopies utmost importance to establish future guidelines photo-driven spin selectivity structures. Here, we provide proof time-resolved electron...
A scalable architecture for quantum computing requires logical units supporting quantum-error correction. In this respect, magnetic molecules are particularly promising, since they allow one to define qubits with embedded correction by exploiting multiple energy levels of a single molecule. The single-object nature encoding is expected facilitate the implementation error procedures and operations. work, we make progress in direction showing how two-qubit gates between error-protected can be...
Noise affecting quantum processors still limits simulations to a small number of units and operations. This is especially true for the simulation open systems, which involve additional operations map environmental degrees freedom. Hence, finding efficient approaches systems an issue. In this work, we demonstrate how using with d > 2 levels (qudits) results in reduction up two orders magnitude (gates) required implement state-of-the-art algorithms. We explore conceptually distinct families...

Theoretically, while weakly...
Investigating the role of chiral-induced spin selectivity in generation correlated radical pairs a photoexcited donor-chiral bridge-acceptor system is fundamental to exploit it quantum technologies. This requires minimal master equation description both charge separation and recombination through chiral bridge. To achieve this without adding complexity entering microscopic origin phenomenon, we investigate implications spin-polarizing reaction operators equation. The explicit inclusion...
