Q-CTRL brand colours. No Shame at all 🤣

No. In Australia the public system provides a strong safety net for everyone and a private supplement lets you "skip the line" for immediate access to non-urgent surgeries.
Many imperfections, but infinitely better than the US private system.

There is a name for the use of violence and murder in the name of a political end.
If that's what youre into, please take it elsewhere.

You're proving my point sadly.
I hate the US health insurance system so much it was a core part of why I moved overseas. It needs dramatic change. Using that to justify murder is not the way

Ions are indeed awesome.
We published ppm a few years ago so it's great to see this crossing the 1ppm barrier!

The work combines deterministic error suppression (see link) with error detection based on flag qubits and stabilizer measurements in the "pre fault tolerance" era...a little bit of #QEC with *no encoding* helps a lot!

It can absolutely be leveraged in other protocols like QEC!
It's a runtime error detection mechanism that post selects out states with errors - but importantly it works without destructive msmt on the state - only on he flag qubits.
We just do those to validate fidelity.

To be clear the state creation is not probabilistic - it's unitary.
We add an error detection step just the way we would if we were using full QEC.

Thanks! Not quite heralded detection as the state creation is purely unitary. However we use stabiliser measurements on ancillae to detect errors (just like QEC).

Kind of you to say Patrick. Looking forward to trying to get back to the good old days of genuine engagement and debate on fun stuff...
