- Comment on Caltech team sets record with 6,100 qubit array 1 week ago:
The achievement in question is the preparation of the neutral atoms, which realize qubits, on this grid. Controlling the placement of such a large number of individual atoms with just light is a somewhat recent breakthrough that is now maturing.
Addressing the atoms and letting them interact is an entirely different beast, but the prerequisite of placement is just as important.

To the practicing statisticians out there: Is BLUE at all relevant in the field? Even if you can formulate your data/problem as a linear regression, wouldn’t maximum likelihood estimation still be the preferred method in most scenarios?

New Zealand also has penguins. But there is no (map) love for NZ.

People how know what an expectation value is are typically not so fond of gambling. Reminds me of the story when a physics conference took place in Las Vegas and resulted in a really low take for the casino.

Typical transition frequencies between two levels of an atom are 10^15Hz. The coupling between atoms and light is on the order of the decay rate at which photons are transmitted, which sits around 10^6Hz.

I describe the atoms using a so called Lindblad master equation. The atoms are kept in this description, but the light field is eliminated using two assumptions:
- The coupling between the two is very weak.
- Correlations between the two decay so fast that this can be considered instantaneous.
The later produces white noise.

I work on quantum systems coupled to noisy environments (noisy as in causing random fluctuations). Atoms coupled to a light field are my specialty. I just got invited by a predatory journal in the field of acoustics, vibrations and noise?!
