Coherent properties of single rare-earth spin qubits.

All-Optical Preparation of Coherent Dark States of a Single Rare Earth Ion Spin in a Crystal.

All-optical addressing and coherent control of single solid-state based quantum bits is a key tool for fast and precise control of ground-state spin qubits. So far, all-optical addressing of qubits was demonstrated only in a very few systems, such as color centers and quantum dots. Here, we perform high-resolution spectroscopic of native and implanted single rare earth ions in solid, namely, a ...

SIMPRE1.2: Considering the hyperfine and quadrupolar couplings and the nuclear spin bath decoherence

SIMPRE is a fortran77 code which uses an effective electrostatic model of point charges to predict the magnetic behavior of rare-earth-based mononuclear complexes. In this article, we present SIMPRE1.2, which now takes into account two further phenomena. First, SIMPRE now considers the hyperfine and quadrupolar interactions within the rare-earth ion, resulting in a more complete and realistic s...

A Chemical Approach to Molecular Spin Qubits: Decoherence and Organisation of Rare Earth Single Ion Magnets DECRESIM

Interfacing superconducting qubits and telecom photons via a rare-earth-doped crystal.

We propose a scheme to couple short single photon pulses to superconducting qubits. An optical photon is first absorbed into an inhomogeneously broadened rare-earth doped crystal using controlled reversible inhomogeneous broadening. The optical excitation is then mapped into a spin state using a series of π pulses and subsequently transferred to a superconducting qubit via a microwave cavity. T...

Rare earth doped crystals for quantum information manipulation

Quantum information manipulation applied to computing is a promising way to dramatically improve some complex calculations and quantum systems simulation. To date, the physical systems able to perform quantum calculations are still very rare and limited to a few quantum bits, so called qubits. It has been proposed that rare earth ions in single crystals at liquid helium temperature could provid...
