Immigration is good. Good for us, good for the immigrant. Allowing immigration is not a nice thing we do for immigrants. It is merely ceasing to do a bad thing to immigrants.

This doesn’t even scratch the surface though. I predict ICE will get tasked with “monitoring election integrity” for the midterms.

The track record with humanitarian institutions and NGOs is much better, admittedly. 8/7

The Peace Prize track record is uniquely terrible. The fundamental flaw is rewarding unstable, real-time geopolitics instead of lifetime achievement. Every time a winner’s legacy curdles, the prize's reputation diminishes, permanently. 7/7

The omissions of deserving people (most famously Gandhi), and the inability to revoke it in bad cases further reinforce the sense that the prize is political and inconsistent. 6/7

Some obvious examples: Obama (for what?), Kissinger/Le Duc Tho (how is this peace?), Rabin/Peres/Arafat (reward people involved in violence), Aung San Suu Kyi (Rohingya), Abiy Ahmed (Tigray). 5/7

Steve Flammia @sflammia.bsky.social · 16/01/2026
This sometimes rewards people involved in violence: many wars end through bargaining with such people. If you reward “peace talks,” you inevitably end up honoring figures many see as undeserving. 4/7

Steve Flammia @sflammia.bsky.social · 16/01/2026
Prizes age badly when a process collapses or the laureate later governs horribly. The committee is sometimes trying to encourage peace in real time, not certify moral sainthood after the fact. 3/7

Steve Flammia @sflammia.bsky.social · 16/01/2026
The Peace Prize is not given as a lifetime achievement award. It often rewards a process (negotiations, ceasefires, diplomacy, advocacy) rather than a settled outcome. That creates a failure mode of premature bets. 2/7

Steve Flammia @sflammia.bsky.social · 16/01/2026
Is there any major, ostensibly legitimate prize with a worse track record than the Nobel Peace Prize? I believe that the “bad picks” aren’t random; they’re structural. 1/7

Interesting bit of sociology: They are really studiously avoiding any mention of quantum computing. First and only mention came in the last few words of the presentation by Johansson.

This would be an important breakthrough if it holds, but I'm skeptical on first glance. Large parts of this were clearly written by a generative AI. Doesn't mean it's wrong, but I suspect it's a "vibe theorem", i.e., not a theorem. I'll wait for Vidick, Regev, etc. to weigh in.

Governments have been over-promised, but program managers aren’t naive. Forcing academics + ‘clueless’ industry partners (imperfectly) aligns theory with reality. It’s frustrating (for both sides!), but still positive-sum. IMO funding a mixture is strictly better than funding only fundamentals.

Bad Policy: Subjecting PhD students and postdocs to 4-year visa limits, subject to immigration officials' review. This bureaucratic overregulation will reduce US competitiveness and weaken US science. There needs to be more awareness and discussion of this terrible idea news.bgov.com/daily-labor-...

Both the House and Senate Committees on Appropriations have now passed funding for science agencies with moderate cuts and flat funding, respectively. Both bills are quite far from the president's budget request, which proposes massive cuts to science funding.

RIP Ray Laflamme, gone too soon. Ray was a stellar scientist, the founding director of ⁦‪the IQC‬⁩ and ⁦‪of CIFAR's‬⁩ Quantum Information program, but more importantly a warm & generous human who built community and helped many (particularly junior researchers). May his memory be a blessing.

Happy to see our book "Why Nobody Understands Quantum Physics" published in English www.panmacmillan.com/authors/fran.... Unlike other popular science books, we explain quantum and its applications in the way working physicists use and understand them, without shying away from the many-body problem.

This! I like to say, "Let p|A denote distribution p conditioned on event A. Imagine a world where the laws of probability are the same, except (p|A)|B need not equal (p|B)|A. Except you don't have to imagine, because it's literally our world! Now explore probabilistic algorithms in this world."

PS: You recover classical (possibly probabilistic) computation if your state stays diagonal in the standard basis at all times. PPS: psd = positive semidefinite, but I guess you knew that.

States 𝜌 are psd matrices with unit trace; measurements E_k are psd and ∑_k E_k = Id; probability of outcome k is Tr(E_k 𝜌); Dynamics are unitary matrices acting by conjugation. Computations start in some state, |0⟩⟨0|^⊗n, apply local unitaries and output is a measurement in the standard basis. QED

My favorite explanation of quantum *mechanics* is "noncommutative probability theory", and quantum computing is just the theory of computation in that universe.
