1. Thread on topological quantum computing (TQC). TQC is a radical approach to quantum computing where the individual topological qubits (Tqb) are intrinsically protected against decoherence by physics, making quantum error correction unnecessary. #quantum #QuantumComputing

The econ @NobelPrize has elicitaded this gem of a cliche from the committee: “we should not take progress for granted.... society must keep an eye on the factors that generate and sustain economic growth” Wow, really? Who could have guessed! https://t.co/fNk6KkheNX

2025 physics @NobelPrize to Clarke Devoret Martinis for their 1985 https://t.co/TCYTTZ1lMd showing macroscopic quantization in Josephson junction forming the basis of SC qubits pursued by Google/others. Amazingly this paper has only ~ 300 citations although the work is well known

From Google AI:"Periodic Labs utilizes an AI-driven, closed-loop system to discover novel materials, including room-temperature superconductors, by having AI design experiments, robots perform synthesis and measurements, and then using the results to refine the AI..." GOOD LUCK

Why are physics departments closing?Just supply/demand market dynamics Number of US degrees awarded annually 8000 (physics),150000 (CS),40000 (chemistry and math and English each ) We physicists think we are special,but are we if students do not want it!

Sami Mitra, @PhysRevLett Senior Editor, gave the CMTC JLDS Colloquium yesterday, and there was, of course, a fun dinner with wonderful bottles of Tempranillo and Barbera-- selfie taken by the Editor outside Bombay Club in DC (from L to R: Mitra, Das Sarma, Sau, Laubscher)

The pure-play QC stock prices are now in the the tulip-mania regime of the 1630s-- who are the fools buying these stocks at these absurd prices and why? It is dot com all over again, perhaps 25 years is long enough for painful memories to be erased. Also, hope springs eternal

It would be truly ironic if AI, which has no physics underlying it, beats QC, whose whole raison detre is solving quantum problems, in ‘solving’ the high-T_c problem just by using all the relevant existing literature blindly!

Can AI predict materials with amazing properties such as robust room temperature superconductivity? Appropriate training is a huge challenge but in principle not impossible. There is no theorem ruling it out @LiamFedus @ekindogus @periodiclabs https://t.co/srXwHwi9mY

Is this an utter lie, white lie, stupidity, or cynical clickbait or all of them? If QC gives you a breakthough in trading, well, Mr HSBC, you should just make loads of money and not brag about it. Sputnik moment!!! NO NO just crazy hype

This is an important development for the already existing huge @UofMaryland quantum eco system including @condensed_the @JQInews @JointQuICS particularly since the MSFT nanowire TQC plarform is based on the theoretical work done at CMTC in 2010 @President_Pines @Microsoft

Gov Moore announces @Microsoft Quantum Center @UofMaryland CMTC is not involved,we found out from the press release, the details are a little vague, but it is big news for quantum ar Maryland, and particularly for CMTC given our total commitment to TQC https://t.co/EphBKUinBf

It is unconscionable for @WSJ glorifying a couple of kooks cynically attacking theoretical physics which they do not understand in order to enrich themselves using the social media. What's next: @WSJ covering Roswell UFOs? Perhaps the flat earth! The Rise of ‘Conspiracy Physics’

Apparently both @PsiQuantum and @QuantinuumQC are now valued ~ $10B-- good for them, and both do interesting/difficult physics, but the Psi claim that QCs "could transform everything" is pure hype just as its claim of creating a QC within "two years" https://t.co/IjQgkpvZjb

Just before leaving Maryland with his PhD our student Nate Foulk hit a @PhysRevLett homerun out of the ballpark by proposing a radical new semiconductor spin qubit platform which has already attracted serious attention from several experimental groups https://t.co/RQHysZVAG1

The @Google antitrust verdict shows how technology has far surpassed the law, e.g., Google must share some of its user data with others, but how? Legally the users agree to share data only with Google,not with others! The extensive use of AI will bring up many more legal issues

In 2010, the success of Alphafold was unimaginable.Perhaps in 2040 we will have an Alphaquantum heuristically solving interacting quantum Hamiltonian with ease. We are not sure if quantum computing will reach that point in 20240 because of the huge problem of error correction

It will be hard because the necessary training data for the interacting quantum matter does not exist because of the exponential problem (and because physics today is not as huge a financial incentive as medical applocations are), but who knows?

This raises the issue of great interest to CMTC in particular and theoretical physics in general.Can some AI-generated pattern recognition method Alphaquantum be developed to give good solutions to diagonalizing the exponentially large Hilbert space of interacting quantum matter?

..practical utility,thus facilitating many aspects of medical research/development.There are surely unknown proteins where Alphafold will fail,but if so the algorithm will improve itself managing to incorporate them into its database.This is a trulparadigmshifting computer use ..

There is a popular misconception that AlphaFold https://t.co/JW0f32r7er SOLVED the protein folding problem, it did not because the problem is NP-hard. What it did is a transformative advance in solving protein folding problem using AI pattern recognition which is of great ......
