Easier randomizing gates provide more accurate fidelity estimation

Kavli Affiliate: Irfan Siddiqi | Summary:Accurate benchmarking of quantum gates is crucial for understanding and enhancing the performance of quantum hardware. A standard method for this is interleaved benchmarking, a technique which estimates the error on an interleaved target gate by comparing cumulative error rates of randomized sequences implemented with the interleaved gate and without […]

Imaging nanoscale photocarrier traps in solar water-splitting catalysts

Kavli Affiliate: Scott K. Cushing | Summary:Defects trap photocarriers and hinder solar water splitting. The nanoscale photocarrier transport, trapping, and recombination mechanisms are usually inferred from ensemble-averaged measurements and remain elusive. Because an individual high-performing nanoparticle photocatalyst may outperform the ensemble average, design rules that would otherwise enhance catalytic efficiency remain unclear. Here, we introduce […]

Picture an Astronomer: Best Practices for Retaining Talent in Astrophysics

Kavli Affiliate: Andrey Kravtsov | Summary:Women are consistently underrepresented in astrophysics yet are simultaneously subject to disproportionate attrition at every career stage. This disparity between demonstrated efficacy in job performance and ultimate career outcome was the primary motivation for the Picture an Astronomer series, which included both targeted public outreach to increase representation of women […]

Generalized Level-Rank Duality, Holomorphic Conformal Field Theory, and Non-Invertible Anyon Condensation

Kavli Affiliate: Jeffrey Harvey | Summary:We study the interplay between holomorphic conformal field theory and dualities of 3D topological quantum field theories generalizing the paradigm of level-rank duality. A holomorphic conformal field theory with a Kac-Moody subalgebra implies a topological interface between Chern-Simons gauge theories. Upon condensing a suitable set of anyons, such an interface […]

Assembling a Bose-Hubbard superfluid from tweezer-controlled single atoms

Kavli Affiliate: Nelson Darkwah Oppong| Summary:Quantum simulation relies on the preparation and control of low-entropy many-body systems to reveal the behavior of classically intractable models. The development of new approaches for realizing such systems therefore represents a frontier in quantum science. Here we experimentally demonstrate a new protocol for generating ultracold, itinerant many-body states in […]

A Seyfert galaxy as a hidden counterpart to a neutrino-associated blazar

Kavli Affiliate: Claudio Ricci | Summary:The origin and production mechanisms of high-energy astrophysical neutrinos remain open questions in multimessenger astronomy. Previous studies have hinted at a possible linear correlation between the hard X-ray and high-energy neutrino emission in active galactic nuclei. New textitNuSTAR observations, first presented here, reveal that blazar PKS 1424+240, located within a […]

Entangled photon triplets using lithium niobate nanophotonics

Kavli Affiliate: Scott K. Cushing | Summary:Multiphoton states are needed for quantum communication and computation. Multiphoton states are significantly more difficult to generate than one- and two-photon states because two individual down-conversion processes must be cascaded. Only efficiencies of $<100$ Hz/mW have been reported to date. We integrate two down-converters on the same thin-film lithium […]

Stable envelopes for critical loci

Kavli Affiliate: Andrei Okounkov | Summary:This is the first in a sequence of papers devoted to stable envelopes in critical cohomology and critical $K$-theory for symmetric GIT quotients with potentials and related geometries, and their applications to geometric representation theory and enumerative geometry. In this paper, we construct critical stable envelopes and establish their general […]
