Varför slutar ungdomar idrotta - med Andreas Ivarsson | Podcast
Idrottspsykologen Andreas Ivarsson gästar podden igen för att prata om sin forskning kring ungdomsidrott – vad som gör träningen rolig, varför vissa fortsätter

A paper recently published in a behavioral sciences journal describes a high school student’s hyperthymesia,
an extraordinary ability to retrieve autobiographical memories.

Teenager with hyperthymesia exhibits extraordinary mental time travel abilities
Scientists in France have documented the case of a teenager with extraordinary autobiographical memory. She can vividly reexperience past events and imagine future ones in detail, highlighting a rare form of mental time travel and emotional memory organization.

Efficient quantum state tomography with Chebyshev polynomials
Quantum computing shows promise for addressing computationally intensive problems but is constrained by the exponential resource requirements of general quantum state tomography (QST), which fully characterizes quantum states through parameter estimation. We introduce the QST with Chebyshev polynomials, an approximate tomography method for pure quantum states encoding complex-valued functions. This method reformulates tomography as the estimation of Chebyshev expansion coefficients, expressed a…

The ordering of hypertrees and unicyclic hypergraphs by the traces of $\mathcal{A}_α$-tensor
For a real number $α\in[0,1]$ and a $k$-uniform hypergraph $\mathcal{H}$, $\mathcal{A}_α(\mathcal{H})=α\mathcal{D}(\mathcal{H})+(1-α)\mathcal{A}(\mathcal{H})$ is called the $\mathcal{A}_α$-tensor of $\mathcal{H}$, where $\mathcal{D}(\mathcal{H})$ and $\mathcal{A}(\mathcal{H})$ are the degree tensor and adjacency tensor of $\mathcal{H}$, respectively. The sum of the $d$-th powers of all eigenvalues of $\mathcal{A}_α(\mathcal{H})$ is called the $d$-th order $\mathcal{A}_α$-spectral moment …

An analytic approach to the stress energy tensor in quantum field theory
We discuss a framework for quantum fields in curved spacetimes that possess a stress energy tensor as a connection one form on a suitable moduli space of metrics. In generic spacetimes the existence of such a tensor is thought to be a replacement for the existence of symmetries that the Minkowski theory relies on. It is shown that the local time-slice property and the implementability of local isometries is a consequence of the existence of a stress energy tensor that is a local field. We prove…

Three-qubit W state tomography via full and marginal state reconstructions on ibm_osaka
We present a three-qubit quantum state tomography scheme requiring a set of 17 measurements, significantly reducing the experimental overhead compared to the conventional 63 Pauli measurements. Using IBM's 127-qubit open-access quantum processor ibm osaka, we prepare the three-qubit W state and employ our tomography scheme to reconstruct it. Additionally, we implement a two-qubit tomography protocol, involving a set of 7 measurements, on ibm osaka to reconstruct two of the two-qubit marginals o…
