By deriving upper and lower bounds on the number of samples required to estimate the parameters of a quantum system, new research in PRX Quantum establishes a systematic framework for estimating sample complexity. 🔗 go.aps.org/4dFmbqT
Schematic of parameter estimation in two parts. Top: a compact statistical model for a quantum parameter estimation protocol. A probe state is independently transformed by the same effective parameter-dependent channel and measured over M repetitions. The resulting M measurement outcomes are then collectively processed to construct an estimator of the parameter. The bottom constructs the effective channel Eθ. The effective channel is realized by inserting multiple uses of the elementary parameter-dependent channel Nθ into the slots of a θ-independent strategy specified by the quantum operations Ci. The double dashed line denotes the ancillary system.

Sometimes a twist is all it takes to create a new field of research. Stacking 2D materials on top of each other and twisting them slightly results in unusual electronic properties. Eva Andrei @RutgersU recently won @KavliPrize for this discovery: energy.gov/science/articles/…
Illustration of two thin layers of graphene stacked on top of each other and then twisted. There is a light coming through the bottom of the stacks used to study the interactions.

Controversy around OpenAI’s claim to have solved the Navier–Stokes problem highlights how researchers could be inadvertently sharing — and absorbing— ideas through chatbots. go.nature.com/4xqxQAR

Who gets credit in the AI era? OpenAI maths bombshell sparks debate

AI-generated content is becoming indistinguishable from human writing. Soon, authenticity and human connection will be the ultimate premium. As you build automated systems, ask: how do we ensure our digital brand keeps its human soul? #AI #Authenticity #HumanConnection

In this blog, I brainstorm that there are six paths towards auto-research, and each path has a different bet underlying it. kindxiaoming.github.io/blog/…

OK, since @arXiv isn't interested, I have made Special Relativity Boot Camp available on Zenodo: doi.org/10.5281/zenodo.22306… There is also a web version: acsu.buffalo.edu/~whkinney/S… Boot camp is a two-to-three week intensive introduction to Special Relativity, suitable for advanced undergraduate students, beginning graduate students, or the sophisticated lay reader.

Special Relativity Boot Camp

These lecture notes form a two- to three-week intensive unit on Special Relativity. The notes present relativity as a fundamentally geometric theory, introducing Minkowski space as a metric space...

The unavoidable “gauge” ambiguity in learning a quantum computer’s noise does not hinder error mitigation, and this remaining degree of freedom can even be optimized to make mitigation dramatically more efficient. Learn more: go.aps.org/4zVUkMF
