… the significance of our new work lies in presenting a clear path to efficiently distribute arbitrary GME states in future quantum networks.

The 1st main challenge is overcome: GME states are precisely & reliably generated in a (trapped-ion) quantum processor & mapped onto traveling photons. 8/8

We confirm this by testing purpose-designed GME witnesses based on fidelities to 8 different GHZ-type states.

In the future, the photons can be mapped onto remote matter-based qubits, e.g., as in doi.org/10.1103/Phys.... Besides being the 1st experimental verification of theoretical ideas ... 7/8

Specifically, three ions are stimulated to each produce a photon (a), with which they are pairwise entangled (b). Then suitable quantum gates and measurements are applied to the ions (c) to remotely prepare GME states of the distributed photons (d). 6/8

In their lab, they demonstrated the core functionalities of a factory node based on trapped ions by producing and verifying GHZ-type GME between three photons generated from the ions and sent to the end nodes, the latter for now represented by photon detectors in our setup. 5/8

In our new paper arxiv.org/abs/2510.15693, EntaQCT www.quitphysics.info/entaqct team member Ida Mishra and myself on the side of @tuwien.at had the pleasure of collaborating with the team of Ben Lanyon at the @uniinnsbruck.bsky.social 4/8

A proposal for realizing a light-matter interface to generate GME is a central matter-based “factory node” that can be programmed to efficiently distribute arbitrary photonic GME states to surrounding clusters of network nodes. 3/8

GME is a non-classical correlation between multiple nodes that is required to make full use of the potential advantages of such a quantum network.

While the quantum systems at the end nodes will likely have to be matter based, light signals are the only viable option for the distribution. 2/8

Ich bin ja der Meinung, eine mit der Geschwindigkeit anwachsende "relativistische Masse" ist kein hilfreiches Modell, das ist nur nötig, wenn man darauf besteht, Impuls als eine scheinbare lineare Funktion "m" mal "v" der Geschwindigkeit und Masse anzuschreiben, was aber eben nur geht wenn m=m(v).

Wait till you hear about Quantum's embargo and pre-print policy!

Few will recognize this as a quote from Al Cappuccino in "And Coffee for All"

I'm a glass-half-full kinda guy

Not sure what I would do without LinkedIn, where would I get my daily dose of people obnoxiously bragging, companies making hyped fantasy claims about imaginary quantum breakthroughs, and people congratulating each other on how long they have already not-yet quit their jobs

So (oder so ähnlich) entstehen übrigens auch viele andere interessante Forschungsprojekte. Die besten Ideen kommen halt oft nicht am Schreibtisch... allerdings kommen zugegebenermaßen zu später Stunde bei der Weihnachtsfeier auch nicht NUR tolle Ideen

We understand why the effect occurs, the question we had was if we should and if so how we could take this effect into account via adapted masks

The actual story is unfortunately way less strange than what it initially sounds like: we were discussing measurement data that should ideally be arranged in a pattern of straight parallel lines, but the actual data came out banana-shaped, we were wondering if this could be amended by suitable masks

Do the four adjectives you used align with the four images? The first three suggest yes, but I dearly hope you did not taste the monkey

Mir ist genau dieser Gedanke auch immer wieder gekommen die letzten Jahre, aber was mir jetzt mehr auffällt: "Wie konnte es damals so weit kommen?" wurde viel thematisiert (zumindest in meiner Schulzeit), aber nicht: "Was hätte man (damals) dagegen tun können?"
