We design and grow rare earth doped crystals in which we aim at controlling optical and spin non-classical states. These materials, produced in the form of bulk and nanostructured single crystals, show extremely long-lived quantum states at low temperature. This unique property in the solid state enables us to address a broad range of applications, from quantum information processing and communication, to spectral analysis and medical imaging. 
 
We belong to the Material for Photonics and Opto-Electronics team of the Institut de Recherche de Chimie Paris. The Institute is a joint unit between Chimie ParisTech graduate school and the Centre National de la Recherche Scientifique.
 

To meet the high demands of quantum technologies, systems with multiple quantum degrees of freedom that can be addressed by light and coupled to other quantum systems in hybrid architectures are strongly needed. We aim at building such devices from solid-state nanostructures that exploit the uniquely narrow optical transitions of rare earth ions. We expect these devices to have a strong impact on quantum communication, quantum sensing and quantum opto-electronics.

A key point of nanoscale quantum systems is to preserve long-lived quantum states despite the larger environmental noise present at surfaces and interfaces, or originating in additional defects.

We develop rare earth doped nanocrystals and thin films with high crystalline quality and purity by bottom-up approaches based on soft chemistry and other techniques. The combination of structural characterization and optical spectroscopy allows us to synthesize nanostructures with low perturbations to the optical quantum states. High performance materials can be used to build hybrid devices, where ions like europium or erbium can provide a quantum interface between light and other quantum systems.

 

Quantum memories are devices capable of faithfully storing photonic quantum states into matter. Their applications include long distance quantum cryptography and more generally quantum networks. Rare-earth ions are promising candidates for solid-state quantum memories, because of the long-lived superposition states of their optical and spin transitions. 

We investigate crystals with multiple degrees of freedom, in which quantum states can be transferred between optical, electron and nuclear spins. In this way, quantum interfaces can be achieved between propagating quantum bits (optical and microwave photons), and long-lived quantum bits (nuclear spins). We aim at increasing quantum states lifetimes by material design and control techniques based on external electromagnetic fields. We also study schemes for improved quantum memories in terms of storage times, efficiency or bandwidth.
High temperature crystal growth techniques are used to produce state of the art samples doped with rare earth ions like europium (optical memories) or neodymium (optical and microwave memories). Optical coherent and high resolution spectroscopy, spectral hole burning, as well as optically detected magnetic resonance allow us to determine all relevant parameters and investigate memory schemes.  

 

Single crystals for quantum memories

Nanostructures for hybrid quantum systems

Spectral analysis 

Long-lived quantum states translate into narrow linewidths. Thus, rare earth doped crystals can exhibit extremely narrow optical linewidths, in the range of a few kHz or even a few 100 Hz in some cases. This enables highly selective spectral filtering that has applications in acousto-optic medical imaging, laser frequency stabilization for metrology or wireless and radar signal analysis. 

We develop crystals in which a strong optical absorption line can be tailored to create narrow transmission windows. These features, called spectral holes, can then be used as a frequency reference or a filter. As an example, for deep tissue imaging in the infrared, we grow thulium doped crystals that can filter light that interacted with ultrasound waves. In this way, the optical signal provides images that carry additional information compared to ultrasound only diagnostic. We also investigate transparent ceramics as an alternative to single crystals. These materials can be produced in large volumes and complex shapes that can benefit to spectral analysis applications, while showing linewidths nearly as narrow as the best single crystals.

Abstract

New paper in Physical Review B on Pr:Y2O3 nanoparticles

October 09, 2019

We investigate the potential for optical quantum technologies of Pr3+:Y2O3 in the form of monodisperse spherical nanoparticles of 150-400 nm in size. We measured optical ioptical homogeneous linewidths of up to 108 kHz and spin T2 of up to 880µs. This value is even higher than that measured for bulk Pr3+-doped crytals. This indicates that this material system is a promising candidate for integration into quantum devices, in particular for realizing spin-photon interfaces emitting indistinguishable single photons.

Paper on naodiamonds in ACS applied Nanomaterials

September 30, 2019

We report on the synthesis of loose NDs by high-power plasma chemical vapor deposition (CVD) without the need of a seeded substrate for nucleation. The as-grown NDs, dispersed in solution, exhibit high crystalline quality and low impurity background. A tunable amount of nitrogen-vacancy (NV) centers is introduced thanks to moderate N2 additions during growth. We then thoroughly assess the optical properties of the produced nanodiamonds. Thanks to this synthesis approach, large-scale production of CVD NDs with a wide tunability of their chemical composition is achieved, paving the way to their use as a platform for exploring quantum sensing applications.

New paper in Physical Review Letters

June 18, 2019

Efficient and reversible optical to microwave transducers are required for entanglement transfer between superconducting qubits and light in quantum networks. To this end, we investigate spin coherence in an optically excited state of an Er3+: Y2SiO5 crystal at temperatures from 1.6 to 3.5 K and found spin coherence and population lifetimes of up to 1.6  μs and 1.2 ms by optically detected spin echo experiments. We eventually propose a quantum transducer scheme that exploits the advantages offered by spin states of the optically excited electronic energy levels.

New paper in Physical Review Applied

June 05, 2019

Using superconducting resonators patterned directly on Y2SiO5 we investigate the use of Y2SiO5 as an alternative to sapphire or silicon substrates for superconducting-hybrid-device fabrication. A NbN resonator with frequency 6.008 GHz and low-power quality factor Q≈400000 is fabricated on a Y2SiO5 substrate doped with isotopically enriched 145Nd. These results demonstrate that Y2SiO5 is an excellent substrate for low-loss, high-Q microwave resonators, especially in applications for coupling to optically accessible rare-earth spins.

New paper in Journal of Physical Chemistry C

May 14, 2019

In this new paper we studied the optical properties of thin Eu or Er doped Y2O3 films grown by Atomic Layer Deposition. We demonstrate that by optimizing the deposition conditions and using appropriate annealing post treatments narrow inhomogeneous lines can be obtained even for films as thin as 11 nm while 1.5ms lifetime is measured for Er ions. These results validate this materialfilms as a suitable platform for photonics applications and provides the first building blocks toward the development of more complex devices for quantum sensing or hybrid structures.

Paper in New Journal of Physics

February 24, 2019

We report on the coupling of the emission from a single europium-doped nanocrystal to a fiber-based microcavity under cryogenic conditions. In particular, we couple an isolated nanocrystal to an optical microcavity and perform cavity-enhanced spectroscopy by resonantly coupling a cavity mode to a selected transition. We detect the fluorescence from an ensemble of few ions in the regime of power broadening and observe an increased fluorescence rate consistent with Purcell enhancement. The results represent an important step towards the efficient readout of single rare earth ions with excellent optical and spin coherence properties.

Paper in RSC Advances

November 05, 2018

Rare earth doped nanoparticles with sub-wavelength size can be coupled to optical micro- or nano-cavities to enable efficient single ion readout and control, a key requirement for quantum processors and high- fidelity single-ion quantum memories. However, producing small nanoparticles with good dispersion and exploitable optical coherence properties, another key aspect for these applications, is highly challenging by most synthesis and nano-fabrication methods. We report here on the wet chemical etching of Eu3+:Y2O3 nanoparticles and demonstrate that a controlled size reduction down to 150 nm, well below the wavelength of interest, 580 nm, can be achieved.  Furthermore, this method allows maintaining long optical coherence lifetimes (T2): the 12.5 ms and 9.3 ms values obtained for 430 nm initial particles and 150 nm etched particles respectively, revealing a broadening of only 10 kHz after etching. These values are the longest T2 values reported for any nanoparticles.

Paper in Nature Materials

August 20, 2018

Solid-state electronic spins are extensively studied in quantum information science, as their large magnetic moments offer fast operations for computing and communication, and high sensitivity for sensing. However, electronic spins are more sensitive to magnetic noise, but engineering of their spectroscopic properties, for example, using clock transitions and isotopic engineering, can yield remarkable spin coherence times. Here we demonstrate simultaneously induced clock transitions for both microwave and optical domains in an isotopically purified171Yb3+:Y2SiO5 crystal, reaching coherence times of greater than 100 μs and 1 ms in the optical and microwave domains, respectively.

Paper in Nature Communications: All-optical control of long-lived nuclear spins in rare-earth doped nanoparticles

May 29, 2018

Nanoscale systems that coherently couple to light and possess spins offer key capabilities for quantum technologies. However, an outstanding challenge is to preserve properties, and especially optical and spin coherence lifetimes, at the nanoscale. We report optically controlled nuclear spins in rare-earth naoparticles with long coherence lifetimes of 2.9 ms at 5 K which is comparable to those obtained in bulk rare-earth crystals. These results open the way to providing quantum light-atom-spin interfaces with long storage time within hybrid architectures.
