It's gone

Boston Cooler in a Bottle is apparently a new limited-run thing and every local Meijer is making sure you know it

Humankind has created many great works of art: David (Michelangelo), Girl with the Pearl Earring (Vermeer), the Parthenon. But I contend that none are greater than Jimmy Barnes appearance in the song "Big Enough". Truly an inspired performance.

Learning mixed quantum states in large-scale experiments
We present and test a protocol to learn the matrix-product operator (MPO) representation of an experimentally prepared quantum state. The protocol takes as an input classical shadows corresponding to local randomized measurements, and outputs the tensors of a MPO which maximizes a suitably-defined fidelity with the experimental state. The tensor optimization is carried out sequentially, similarly to the well-known density matrix renormalization group algorithm. Our approach is provably efficien…

Legacy of Avicenna in Astronomy
The paper reassesses the largely neglected contribution of Avicenna (Ibn Sina, 980-1037) to medieval Tajik-Persian astronomy. Drawing on published primary and secondary sources, it reconstructs the main directions of his scientific activity - the construction of an observatory at Isfahan, the design of a high-precision angular instrument that anticipates the modern vernier principle, the formulation of an original method for determining terrestrial longitude from lunar culmination, a systematic…

The evolution of CME sheath turbulence from L1 to Earth: Wind and MMS observations of the 2023-04-23 CME
An interplanetary shock driven by a coronal mass ejection (CME) containing an interval of sub-Alfvénic flow impacted Earth on April 23, 2024. In this article, we analyze the turbulence in the sheath region between the shock and CME to determine how it evolves from L1 (as observed by Wind) to Earth (as observed by MMS, upstream of the bow shock). Wind and MMS were separated by $55\,\mathrm{R_{E}}$ in the dawn-dusk direction, but the shock normals differ by only $2.8^{\circ}$ and the Pearson cor…

Simulated non-Markovian Noise Resilience of Silicon-Based Spin Qubits with Surface Code Error Correction
We investigate the resilience of silicon-based spin qubits against non-Markovian noise within the framework of quantum error correction. We consider a realistic non-Markovian noise model that affects both the Larmor frequency and exchange energy of qubits, allowing accurate simulations of noisy quantum circuits. We employ numerical emulation to assess the performance of the distance-3 rotated surface code and its XZZX variant, using a logical qubit coherence time metric based on Ramsey-like exp…
