Wij onderzoeken mogelijkheden om de bouwstenen van dit quantum internet te verbeteren. De relatieve nieuwe van der Waals materialen die wij hiervoor gebruiken bieden ongekende mogelijkheden omdat ze laag-voor-laag kunnen worden ontworpen en gefabriceerd. En door deze ultradunne materialen tussen twee spiegels op te sluiten worden hun goede eigenschappen nog verder versterkt. De combinatie van nieuwe materialen met optische opsluiting biedt de mogelijkheid om de, tot nog toe bescheiden, communicatiesnelheid op het quantum internet met vele factoren 10 te vergroten.", "summary_en": "After the first impressive steps towards the construction of a national quantum network, many challenges lay ahead. This project tries to tackle some of these challenges. It will explore the use of quantum emitters in 2D van der Waals materials like hexagonal boron nitride (hBN), as alternative to the NV-centers in diamond that are currently used. And it will study and optimize the use of optical cavities to boost the performance of these emitters. The project is curiosity driven but could result in better components for the quantum internet, with prospects to increase the communication rates by orders of magnitude.", "award_amount": 655348, "grant_id": "https://doi.org/10.61686/TPLHZ83288", "summary_updates": [ { "submission_date": "2026-08-31T14:47:37", "update_en": "New mirrors and improvemens in the technical/mechanical design offer better control over the optical radiation trapped in our micro-cavities.
