Researchers at the Walther-Meißner-Institut (WMI) have just reported on first demonstration experiments using their prototype superconducting QuLAN device (arXiv:2308.12398). Specifically, they have successfully distributed entangled microwave states across a ~6m…
Theorists at TU Wien and the Walther-Meißner-Institut have proposed and analyzed a scheme for distributing multi-qubit entanglement in a robust and fully autonomous way. In their scheme, qubits arranged along…
The experimental team at ETH Zürich has implemented a loophole-free test of Bell’s inequality in a superconducting setup. To achieve this breakthrough, the researchers created pairs of entangled qubits across…
Together with a partner from Sun Yat-sen University in China, CSIC and TU WIEN have proposed a new control scheme for implementing arbitrary lineart transformations between multi-mode bosonic quantum registers. …
Apart from building quantum computers in the first place, another nontrivial challenge is to verify that these computers then operate as expected. The theory group at MPQ has now proposed…
Researchers at IST Austria have demonstrated for the first time the deterministic generation of entanglement between optical and microwave photons (arXiv:2301.03315). Together with their colleagues from TU Wien, they have…
Workshop & Summer School After two years of travel restrictions we are happy to announce that both our workshop on superconducting quantum networks as well as our summer school can…
In a collaboration with MPQ, J. Tura at aQa could show how a coherent link between two parties A and B can assist in finding the ground state or other…
TU Wien and IST have analyzed the distribution of entanglement over long distances by driving separated quantum nodes with the output of a two-mode squeezed parametric amplifier. This scheme is…
Deterministic quantum operations in microwave quantum links The theory teams in Madrid and Vienna have proposed and analyzed a set of deterministic quantum operations for implementing gates between remote qubits…
