Many interesting discussions regarding some of our recent works

Thanks to all @ICSCRM2023 for this outstanding event!

Strong @QuanTELCO presence last week at @ICSCRM2023, including contributed talks and posters from @HeriotWattUni @cristian_bonato, @liu_universitet, @univgroningen, @bme_hu and an invited talk from @iqoqivienna @oeaw

With our @TelcoQuan partners, we show an ultra-narrow inhomogeneous distribution (~100 MHz!) for telecom vanadium centres in isotopically-enriched SiC. This is great, as quantum networks require indistinguishability of photons emitted by separate centres https://t.co/SkhUOWj6un

We developed a grayscale lithography to make 20,000 hemispherical solid immersion lenses in SiC in just a couple of days! (1/2)

@univienna have developed silicon microcavities with small mode volume and very high finesse which are tailor-made for O-band #quantum systems:

We will need to enhance the interaction of the spins with #telecom #photons. This goal requires optical #microcavities of the highest quality. We will test two approaches: photonic crystal resonators and #silicon open-access #microcavities.

@SouthamptonUNIV are continuing the path towards integration with #photoniccrystal #microcavities in #siliconcarbide, as shown in previous work:

Meanwhile, the material developments that @QuanTELCO will benefit from have led to detailed investigations of several other systems in #siliconcarbide. Several of these are of interest for #quantumtech:

The large nuclear spin (S=7/2) leads to a rich level structure and intricate spectra. A challenge towards #qubits, or an opportunity for a #qudit?

[QuanTELCO @TelcoQuan]

#Vanadium in #siliconcarbide looks promising for #quantumtech. Its optical emission is bright and sharp, but there are many mysteries regarding its spin structure. Our partners @UniKonstanz @univgroningen @QUANTUMunivie have begun to unravel them:

Only a few weeks left until #Christmas!
Time to start looking at what QuanTELCO has been up to this year.
Our goal is to identify and test promising spin centres in #crystals for #Quantumcomm, specifically in the O-band (1260 nm – 1360 nm).

[QuanTELCO @TelcoQuan]

This week’s highlight is an in-depth review in Nature Reviews Materials on spin centres and their applications in #quantum #technology, co-authored by QuanTELCO partner Prof. Adam Gali at @BME_hu:
