A two-dimensional 10-qubit array in germanium with robust and localised qubit control

Kavli Affiliate: Menno Veldhorst | First 5 Authors: Valentin John, Cécile X. Yu, Barnaby van Straaten, Esteban A. Rodríguez-Mena, Mauricio Rodríguez | Summary: Quantum computers require the systematic operation of qubits with high fidelity. For holes in germanium, the spin-orbit interaction allows for textit{in situ} electric fast and high-fidelity qubit gates. However, the interaction also […]

Quantum particle in the wrong box (or: the perils of finite-dimensional approximations)

Kavli Affiliate: Felix Fischer | First 5 Authors: Felix Fischer, Daniel Burgarth, Davide Lonigro, , | Summary: When numerically simulating the unitary time evolution of an infinite-dimensional quantum system, one is usually led to treat the Hamiltonian $H$ as an ”infinite-dimensional matrix” by expressing it in some orthonormal basis of the Hilbert space, and then […]

Impact of reionization history on constraining primordial gravitational waves in future all-sky cosmic microwave background experiments

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Hanchun Jiang, Toshiya Namikawa, , , | Summary: We explore the impact of the reionization history on examining the shape of the power spectrum of the primordial gravitational waves (PGWs) with the cosmic microwave background (CMB) polarization. The large-scale CMB generated from the reionization epoch is important […]

Unveiling the Cosmic Chemistry II: “direct” $T_e$-based metallicity of galaxies at 3 $< z <$ 10 with JWST/NIRSpec

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Priyanka Chakraborty, Arnab Sarkar, Randall Smith, Gary J. Ferland, Michael McDonald | Summary: We report the detection of the [O III] auroral line in 42 galaxies within the redshift range of $3 < z < 10$. These galaxies were selected from publicly available JWST data releases, including […]

Transcribing and Translating, Fast and Slow: Joint Speech Translation and Recognition

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Niko Moritz, Ruiming Xie, Yashesh Gaur, Ke Li, Simone Merello | Summary: We propose the joint speech translation and recognition (JSTAR) model that leverages the fast-slow cascaded encoder architecture for simultaneous end-to-end automatic speech recognition (ASR) and speech translation (ST). The model is transducer-based and uses a […]

Observational Signatures of Disk Winds in Protoplanetary Disks: Differentiating Magnetized and Photoevaporative Outflows With Fully Coupled Thermochemistry

Kavli Affiliate: Lile Wang | First 5 Authors: Xiao Hu, Jaehan Bae, Zhaohuan Zhu, Lile Wang, | Summary: Magnetized winds and photoevaporative winds are critical in shaping protoplanetary disk evolution. Using 2D axisymmetric (magneto-)hydrodynamic simulations with Athena++ implementing fully coupled thermochemistry, we investigate the signatures of the two winds in CO and [C~I] ALMA observations, […]

Scattering theory of higher order topological phases

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: R. Johanna Zijderveld, Isidora Araya Day, Anton R. Akhmerov, , | Summary: The surface states of intrinsic higher order topological phases are protected by the spatial symmetries of a finite sample. This property makes the existing scattering theory of topological invariants inapplicable because the scattering geometry […]
