Congratulations to Giulia Mancini for receiving the IUPAP Young Scientist Prize in Optics! In 2005 the International Union of Pure and Applied Physics (IUPAP) created the Young Scientist Prizes for its commissions. The international Commission of Optics (ICO), as an Affiliated Commission of IUPAP, decided in 2008 to adopt the IUPAP Young Scientist Prize in Optics. The IUPAP prize in optics will be awarded annually through ICO to a scientist who has made noteworthy contributions to applied optics and photonics during a maximum of 8 years of research experience after having earned a PhD degree. Career interruptions will not be counted as time of research experience.

In the past month, the group has put up two new preprints. 

- In the strontium experiment, we report the generation of entangled Bell states, prepared in optical clock qubits, whose phase coherence persists for more than 4 seconds. This uses a gate scheme proposed by M. Martin and I. Deutsch, based on Rydberg-mediated interactions. See the preprint here.

- On the Ytterbium experiment, we report our first results preparing, controlling, and detecting arrays of nuclear spin qubits of ¹⁷¹Yb. We observe high fidelity control with sub-microsecond pulse times. We also demonstrate low-entropy array preparation through deterministic loading techniques via the use of narrow-line transitions and Raman-sideband cooling to near the motional ground state.
