Opening of NanoArt exhibition: Lens(less)ness
The NanoArt project of QuTech, initiated by Laurens Feije and Gerben Timmer from Taminiau Lab, had its first large-scale exhibition at the TU Delft Library. NanoArt brings the beauty of cleanroom work to the public. This exhibition featured art pieces not only from Laurens and Gerben, but also from QuTech colleagues David van Driel, Figen Yilmaz, Marta Pita Vidal, Nina Codreanu, Nick van Loo and Siddharth Singh.

Our realisation of a time crystal is published in Science
Researchers from the Taminiau lab at QuTech created a time crystal, a novel exotic quantum phase of matter, using a quantum computer based on diamond. Together with a simultaneous experiment by Google (preprint), the results shed new light on the physics of out-of-equilibrium quantum systems. The team reports their findings today in Science.

NWA grant
Our proposal “Quantum microscopy: A new tool for future technologies” has been accepted (NWO website). We will investigate scanning probe magnetic imaging based on defects in diamond with a multi-disciplinary team that includes Toeno van der Sar (Delft), Richard Norte (Delft), Tjerk Oosterkamp (Leiden), TNO, Applied Nanolayers BV and Leiden Spin Imaging BV.
NWA: Connecting science and society.
The Dutch government has recently increased its investment in research and innovation. Part of this extra funding is intended for the NWA research programme that NWO is realising on behalf of the Ministry of Education, Culture and Science. The overarching aim of this programme is to improve the connection between science and society. The need to structurally strengthen this connection is widely felt and supported. To achieve this aim, the NWA programme will encourage research relevant for society, facilitate knowledge sharing via interdisciplinary and knowledge-chain-wide collaboration, and proactively involve societal partners in the formulation, setting up and realisation of the research. The dialogue between science and society will be further fuelled by targeted communication and outreach activities and by the active involvement of citizens in science and research (e.g. through citizen science and co-creation). In addition, the programme will contribute to the sustainability and innovativeness of routes and networks.

Radio interview on NPO1 (Dutch)
Tim gives his take on a recent breakthrough paper on the Dutch radio. Click here for the radio interview. In the paper, published today in Science, the authors demonstrate that single NV centers can be read out through the electrical current they generate. This provides an alternative to the traditional optical readout, with the potential for better integration is small electronics devices. Fun fact: one of the authors is Takashi, who now joined our team at QuTech.

Quantum Zeno dynamics published
Our paper on protecting logical quantum states in subspaces formed through the quantum Zeno effect is published in Nature Communications. The work explores protecting multiple logical entangled qubits from environmental noise and provides an opportunity to study the interplay between frequent quantum measurement and correlated noise such as non-Markovian noise.
See the press release and these selected news articles (Tweakers, PhysOrg) for more.

Quantum Error Correction published in Nature Communications
Because quantum states are extremely fragile, large-scale quantum information processing is impossible without quantum error correction. In our latest publication in Nature Communications we realize active quantum error correction based on non-destructive measurements and real time feedback. This experiments marks the first time that quantum states are continuously protected by repeatedly detecting errors and actively corrected through classical logic and real time feedback, essential elements of fault-tolerant quantum computations.
The work was covered by several media, such as the volkskrant, tweakers.net and BNR radio, and even drew the attention of the Dutch royal family! See the videos and cartoon below for a basic explanation of quantum error correction.
Cartoon version of the experiment. (1) A logical quantum bit is encoded in three physical qubits (nuclear spins). (2) Errors are detected through non-destructive stabilizer measurements using an ancilla qubit (electron spin). (3) Errors are corrected through fast real-time feedback. Steps 2 and 3 are repeated in order to continuously protect the quantum state. Image by Wolfgang Pfaff, edited by Julia Cramer.

Top 10 scientific breakthrough!
Our loophole-free Bell test was picked as a top 10 scientific breakthrough of 2015 by the magazine Science. Ultimately we lost out on the number 1 spot to CRISPR, the powerful genome editing technique. In the internet voting by the public, the New Horizons missions images of Pluto took first place, with our Bell test coming in 5th!
Just a few days later Nature selected our experiment as one of the science events that shaped 2015!

The first loophole-free Bell test
Our loophole-free Bell test has now been published in Nature. In this experiment performed at the Hanson lab we entangled two nitrogen-vacancy (NV) centers in diamonds placed in laboratories on opposite sides of the TU Delft campus (1.3 kilometer). We then used this entanglement to demonstrate a violation of Bell’s inequality. Because the NV center spins were measured with high accuracy and because the complete measurement (choice of measurement basis, spin readout, storage of result in classical electronics) was performed in a time so short that no communication between the labs was possible, the experiment closes all loopholes that were present in previous experiments.
Our results reject the hypothesis that nature obeys the principle of local causality (or local realism), providing the strongest evidence yet that the world is fundamentally non local. The only remaining ways to save the local casual worldview is to invoke that the measurement choice was already determined at an earlier time or that the results stored were still altered after they were saved in the classical computers. Such theories can be further restricted in future experiments – most excitingly by using humans on earth and on the moon/in space to select the measurement settings and record the data – but can never be completely excluded.
The result made quite a splash in the media and was even featured on the cover of the New York Times. A good place to start is the coverage by the economist and two of the features by Nature (first, second).
This experiment was based in the Hanson lab at QuTech and is a collaboration with the groups of Stephanie Wehner (QuTech), Morgan Mitchell (ICFO), Valerio Pruneri (ICFO) and Matthew Markham and Daniel Twitchen (Element Six).
