Where were we: Boaz Barak proposed a “law of nature” that if there is a physical device that can make a certain computation C, then there is a quantum circuit that computes C. 1/11

Aram remarked that Boaz's proposed law is a variant of the strong Church Turing thesis. Correct! 2/11
I proposed a refinement of the general law. There are cases where we can analyse classes of devices (or natural processes) and can conclude that for them there is even a classical circuit that computes what they compute. 3/11
I gave a few examples 1) Computations that take place in Boaz's laptop can be carried out by a classical circuit.
4/11
2) Computations carried out by Boaz's brain can be carried out by a classical circuit. 5/11
Here is another (plausible) example: 3) Protein folding for proteins occurring in nature can be described by classical circuits. 6/11
Boaz responded that “nature” does not have a notion of a “classical device” - nature is quantum.  7/11
This is a nice slogan but it is irrelevant to the fact that *we* can recognize physical devices or fragments of quantum physics that can likely be described by classical circuits. 8/11
In a 2014 paper Kindler and I considered noisy boson sampling. Based on some noise model that we described we concluded that such devices could be described by classical circuits. 9/11
One plausible conclusion that we offered was that it is unlikely that photonic boson sampling devices would exhibit huge quantum computational advantage (HQCA) just like it is unlikely that Boaz's brain or Boaz's laptop will exhibit HQCA. 10/11
My general argument regarding NISQ systems extends this interpretation of our 2014 results. Boson sampling is conceptually and technically simple.

One of the judges this story mentions is William Cassidy, who was promoted from an Atlanta IJ position to a BIA member position in 2019 by the Trump DOJ. Cassidy has an awful history that has been well-documented, but I'm still enraged reading this reporting.


The story notes that the EOIR Director served as an ICE attorney in Atlanta and practiced before Cassidy for years. And it points to FOIA records unearthed by Bryan Johnson showing they remain friendly.

A trove of complaints against Cassidy was published by AILA in 2019 after FOIA litigation. They generally show misconduct, substantiated in the record, followed by "written counseling" etc.

One way Cassidy could avoid discipline is by turning off the recording device during the hearing. If he made a lewd or offensive comment off the record, all the EOIR would do is listen to the recording. If it's not there, the complaint is "unsubstantiated" https://t.co/wUeBPEEbpV


In that case, Cassidy joked about a detained immigrant saying he missed his wife. The complaint was dismissed because the ACIJ found "no levity or joking" in the comment.
How to avoid (successful) accusations of defamation on Twitter. A few thoughts from someone who is NOT a libel lawyer, but does say very critical things about named individuals. 1/

1. Facts are different from opinions. But stating an opinion can imply a fact.

2. When I tweet I aim to be sure A. I show the *facts* I am basing my *opinion* on. B. I have good reason to believe the *facts* are true. C. My opinion is reasonable based on the facts.

Here I am calling Arron Banks a racist (opinion). Pointing out this is because he called for mosques to be demolished (fact). 4/


I can prove this fact - and others - about what Banks has said. And I can justify why in my opinion that shows he’s a racist. 5/
This is what he wants to do.

No matter how this trial plays out, the US will remain divided between those who choose truth, Democracy, and rule of law and the millions who reject these things.

The question is how to move forward.

My mantra is that there are no magic bullets and these people will always be with us.

Except for state legislatures, they have less power now than they have for a while.

The only real and lasting solutions are political ones. Get Democrats into local offices. Get people who want democracy to survive to the polls at every election, at every level.

It’s a constant battle.

Maybe I should tell you all about Thurgood Marshall’s life to illustrate how hard the task is and how there will be backlash after each step of progress.

4/

Precisely. That's why Thurgood Marshall's life came to mind.

We are still riding the backlash that started after the Supreme Court decision in Brown v. Board of Education.

That's why I keep saying there are no easy
