Kavli Affiliate: James J. Bock | First 5 Authors: Yun-Ting Cheng, James J. Bock, , , | Summary: Several fluctuation studies on the near-infrared extragalactic background light (EBL) find an excess power at tens of arcminute scales ($ellsim10^3$). Emission from the intra-halo light (IHL) has been proposed as a possible explanation for the excess signal. […]
Kavli Affiliate: Michael A. McDonald | First 5 Authors: Keunho J. Kim, Matthew B. Bayliss, Allison G. Noble, Gourav Khullar, Ethan Cronk | Summary: The environments where galaxies reside crucially shape their star formation histories. We investigate a large sample of 1626 cluster galaxies located within 105 galaxy clusters spanning a large range in redshift […]
Kavli Affiliate: Stephanie Wehner | First 5 Authors: Guus Avis, Francisco Ferreira da Silva, Tim Coopmans, Axel Dahlberg, Hana Jirovská | Summary: We numerically study the distribution of entanglement between the Dutch cities of Delft and Eindhoven realized with a processing-node quantum repeater and determine minimal hardware requirements for verifiable blind quantum computation using color […]
Kavli Affiliate: Eric Miller | First 5 Authors: Ryohei Matsumiya, Hiroaki Akatsuka, Chris P. Bidinosti, Charles A. Davis, Beatrice Franke | Summary: The TRIUMF Ultra-Cold Advanced Neutron (TUCAN) collaboration aims at a precision neutron electric dipole moment (nEDM) measurement with an uncertainty of $10^{-27},ecdotmathrm{cm}$, which is an order-of-magnitude better than the current nEDM upper limit […]
Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Akel Hashim, Stefan Seritan, Timothy Proctor, Kenneth Rudinger, Noah Goss | Summary: Contemporary methods for benchmarking noisy quantum processors typically measure average error rates or process infidelities. However, thresholds for fault-tolerant quantum error correction are given in terms of worst-case error rates — defined via the diamond […]
Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Jordan Hines, Marie Lu, Ravi K. Naik, Akel Hashim, Jean-Loup Ville | Summary: Randomized benchmarking (RB) protocols are the most widely used methods for assessing the performance of quantum gates. However, the existing RB methods either do not scale to many qubits or cannot benchmark a universal […]
Kavli Affiliate: Takeo Higuchi | First 5 Authors: Latika Aggarwal, Swagato Banerjee, Sunil Bansal, Florian Bernlochner, Michel Bertemes | Summary: Belle II is an experiment operating at the intensity frontier. Over the next decades, it will record the decay of billions of bottom mesons, charm hadrons, and tau leptons produced in 10 GeV electron-positron collisions […]
Kavli Affiliate: Sander Otte | First 5 Authors: Laëtitia Farinacci, Lukas M. Veldman, Philip Willke, Sander Otte, | Summary: Historically, electron spin resonance (ESR) has provided excellent insight into the electronic, magnetic, and chemical structure of samples hosting spin centers. In particular, the hyperfine interaction between the electron and the nuclear spins yields valuable structural […]
Kavli Affiliate: Huajia Wang | First 5 Authors: Liangyu Chen, Huajia Wang, , , | Summary: Mutual information serves as an important measure of correlation between subsystem components. In the framework of quantum field theories (QFTs) they have better regulated UV behavior than entanglement entropy, and thus provide more direct access to universal aspects of […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Roger de Belsunce, Steven Gratton, George Efstathiou, , | Summary: We present constraints on primordial B modes from large angular scale cosmic microwave background polarisation anisotropies measured with the Planck satellite. To remove Galactic polarised foregrounds, we use a Bayesian parametric component separation method, modelling synchrotron radiation […]
