compares Microsoft's Majorana 2 result to "Finding an image of Jesus in toast by looking through an entire bakery's worth of loaves. If you're looking into something which is essentially just random physics, eventually you will find the Jesus in your toast."

I gave a lecture on quantum hype and quantum bullshit for our master's students this week. Afterwards they looked at Microsoft's Majorana 2 announcement and analyzed it from different sides: original press release, publication, media coverage and expert response, and then made their own conclusions.

Most journals (including Nature and Science) require declaring AI use. How come there is no mention of AI, LLMs, "agents" or "Microsoft Discovery" anywhere in the paper while the official press release talks more about agentic AI contributions than majorana qubits?

But it comes on the back of this. 🤷♂️ An alarming amount of investment—public and private—is probably based on the misunderstanding that quantum computers solve problems in parallel.

The day when AI can do quantum computing better than you will arrive sooner than you think! The best way to prepare for this is to start taking art classes already now so that when your salary is replaced by UBI you can easily switch to producing bad art full time.

It would be hugely disappointing if the device that was officially announced as "lending credence to the notion that quantum computation occurs in many parallel universes" and whose predecessor was used to "create a wormhole" would now be used by mere mortals to simulate some boring Hamiltonian.

Exponential quantum advantage in processing massive classical data
Broadly applicable quantum advantage, particularly in classical data processing and machine learning, has been a fundamental open problem. In this work, we prove that a small quantum computer of polylogarithmic size can perform large-scale classification and dimension reduction on massive classical data by processing samples on the fly, whereas any classical machine achieving the same prediction performance requires exponentially larger size. Furthermore, classical machines that are exponentially larger yet below the required size need superpolynomially more samples and time. We validate these quantum advantages in real-world applications, including single-cell RNA sequencing and movie review sentiment analysis, demonstrating four to six orders of magnitude reduction in size with fewer than 60 logical qubits. These quantum advantages are enabled by quantum oracle sketching, an algorithm for accessing the classical world in quantum superposition using only random classical data samples. Combined with classical shadows, our algorithm circumvents the data loading and readout bottleneck to construct succinct classical models from massive classical data, a task provably impossible for any classical machine that is not exponentially larger than the quantum machine. These quantum advantages persist even when classical machines are granted unlimited time or if BPP=BQP, and rely only on the correctness of quantum mechanics. Together, our results establish machine learning on classical data as a broad and natural domain of quantum advantage and a fundamental test of quantum mechanics at the complexity frontier.
