Abstract: One of the most remarkable discoveries in quantum physics is that long-range entangled qubits can give rise to emergent gauge fields and collective excitations exhibiting generalized ('anyonic') exchange statistics. Despite the importance of such 'topological' states for quantum information processing, they are extremely challenging to find in materials. In this talk, we explore how novel 'bottom-up' quantum devices---built atom by atom, qubit by qubit---challenge this status quo.

Abstract:

Abstract: QBism (pronounced like cubism) is a foundational program for quantum mechanics premised on the idea that quantum probabilities should be understood as Bayesian probabilities—that is, quantified degrees of belief or gambling attitudes.

Abstract: Recent advances in single-molecule imaging technologies have made it possible to study gene expression dynamics at unprecedented resolution. In this talk, I will describe two projects that use this technology to visualize, quantify, and model gene expression at different levels. The first project involves the study of RNAP2 phosphorylation at a single-copy gene. Here, I combined three-color fluorescent microscopy with antibody-based probes that bind the different phosphorylated forms of endogenous RNAP2.

Abstract: Large-scale quantum computers will require error correction in order to reliably perform computations. However, the hardware overhead for error correction remains dauntingly large, with each logical qubit potentially requiring thousands of physical qubits for reliable operation. One promising approach to reducing the overheads of error correction is to tailor quantum error correcting codes to the dominant noise in the qubit hardware.

Abstract:

Abstract: The solar wind is a turbulent plasma regime that supports current sheets of many spatial scales. The vast majority of current sheets are narrower than 400 km. We associate these kinetic-scale current sheets with solar wind turbulence at 1 AU. The largest current sheet is 64,000 km wide on average, or 150 times wider than the more prevalent and turbulent ones.

Abstract: In 1974, Stephen Hawking argued that black holes destroy information, counter to a fundamental principle in quantum mechanics, calling into question how general relativity and quantum mechanics could ever be unified. Ever since then physicists have wrestled with this question.

Abstract: A distinguishing feature of the cell envelope of Gram-negative bacteria is the presence of an outer membrane, which is highly impermeable to antibiotics. Transmembrane -barrel proteins embedded in the outer membrane are responsible for establishing this permeability barrier. Folding and integration of -barrels into the outer membrane are facilitated by the conserved protein complex -barrel assembly machine (BAM).
