One of our devices, where a #superconducting #qubit is coupled to a high-overtone bulk #acoustic #wave #resonator. Still amazed that #quantum #mechanics effects can be seen in such a macroscopic object!

Our work on making a mechanical qubit in @ScienceMagazine https://t.co/OXUmZICDb3

We wrote a small review on displacement and rotation sensing with continuous-variable systems https://t.co/gC68xPyg6f, hope you find it useful!
It collects a number of theory results, as well as some new observation...

Quantum entanglement in phase space

We propose entanglement criteria based on Wigner function measurements, applicable to both Gaussian and non-Gaussian states. Notably, we demonstrate cases where these criteria are both necessary and sufficient. https://t.co/nscyUI6rKq

Happy that our work is finally published!

We have realized a mechanical Kerr parametric oscillator, and use it to prepare nonclassical states of motion with high Fisher information!

Isn't this fun?
Can you guess what it is? ;)

@jusuf26774430 I don't like photons

[Matteo Fadel @thefad5]

@blattnerma Almost!

[Matteo Fadel @thefad5]

I love how people complain when they see a plot without error bars. On the contrary, when there are error bars no one checks if they were computed correctly.

[Matteo Fadel @thefad5]

Yes, a mechanical qubit: take a massive oscillator and make it so non-linear that the energy of having two excitations is much different than twice the energy of having one excitation. In this way you can address each energy transition independently, like in a qubit...

[Matteo Fadel @thefad5]

What would you do with a mechanical qubit?

[Matteo Fadel @thefad5]

Almost as fun as steering quantum states, I spent last weeks steering a boat around the North see.
Did you know that one can sail at even three times the speed of the incoming wind? To me it still sounds like crazy

[Matteo Fadel @thefad5]

@shoyip Yesss!!!

Why some of the best conferences are in Italy?
1) talks start at 10am, max 5 per day
2) great food and coffee
3) venues be like:

Classical mechanics is still full of fascinating phenomena

@Jayich_Lab Interesting! And why radium?

[Matteo Fadel @thefad5]

@AndreiVraji Yes, it's very silent. But even if it wasn't the case, the aesthetic is much better.
