🚀 Oh, look! The University of Warsaw 🎓 just discovered a "hidden" terahertz world that apparently nobody thought to check before. Quantum antennas made of Rydberg atoms are now the latest craze to make your science paper sound sci-fi without actually explaining anything. 📡🔍

New quantum antenna reveals a hidden terahertz world

Researchers at the University of Warsaw have unveiled a breakthrough method for detecting and precisely calibrating terahertz frequency combs using a quantum antenna made from Rydberg atoms. By combining atomic electrometry with a powerful terahertz-to-light conversion technique, they achieved the first measurement of a single terahertz comb tooth—something previously impossible due to the limits of electronics and optical tools.

Physicists Found an Entirely New Way of Measuring Time

Determining the passage of time in our world of ticking clocks and oscillating pendulums is a simple case of counting the seconds between 'then' and 'now'.

New spin-squeezing techniques let atoms work together for better quantum measurements

Opening new possibilities for quantum sensors, atomic clocks and tests of fundamental physics, JILA researchers have developed new ways of "entangling" or interlinking the properties of large numbers of particles. In the process they have devised ways to measure large groups of atoms more accurately even in disruptive, noisy environments.

#qibo I'm a fan.

On Thursday I talked to Stefano Carazza who is pushing forward the vision to have a #FOSS full stack #quantumComputing package.

The package is called Qibo and it's freely available. As in free software.

We talked about about how at a certain stage adoption will become relevant, for now releasing #QiboCal and #QiboLab is the focus.

I say relevant, because it's not going to be an issue, a challange at most. Why, there's a ton of new setups emerging and experimentalists prefer to run everything from a single jupyter notebook and have control over what is happening in their lab rather than be restricted.

A researcher is not building abinitio a #quantumDevice to be limited by #IP or some nonsense that our societal system tends to generate.

Qualitatively new ideas are continuously surfacing and to seamlessly make academic progress we need #FOSS and integrate our efforts. Private interests should not limit what researchers are doing; vide our flawed publication system.

We need 2 things:
- theorists publishing their protocols with code integrated into Qibo as e.g. a calibration, optimization or circuit routine.
- experimentalists setting up Qibo drivers.
Qibo is a bridge between theory and experiments that is going to stand on the FOSS principle. A principle that will allow us to make more progress than without it.

#superconducting qubits, #RydbergAtoms, #trappedIons, #integratedPhotonics have similar requirements and Qibo is going to make them buzz 😊😄

If that sounds similar to what you think is already doing that then no. The FOSS feature needs to be present otherwise you're making a managerial design error that will show up down the line.
