Metalloenzymes catalyze complex reactions with unprecedented efficiency. These enzymes are promising candidates for various biotechnological applications, including producing alternative fuels and pharmaceuticals. Oftentimes, the innate complexity of these metalloenzymes prohibits a true appreciation of their full capability and a detailed understanding of their structure-function relationships. One approach to alleviating this issue is to design artificial metalloenzymes (ArMs) that still contain the metal of interest in a biomolecular environment, allowing the chemistry to be performed in aqueous media. The protein scaffold prevents unwanted side reactions. In addition, the protein environment allows one to alter outer sphere interactions to fine-tune their reorganization energies and reactivity. In this seminar, I will present two complementary approaches to designing Ni and Cu-containing ArMs – artificial hydrogenases and artificial C-H peroxidation catalysts utilizing protein reengineering and de novo protein design approaches.

"Dynamical Error Reshaping for Dual-Rail Erasure Qubits"
Presented by Ed Barnes, Virginia Tech

Hosted by: Kai-Mei Fu - C2QA Deputy Director, University of Washington
Erasure qubits—-qubits designed to have an error profile that is dominated by detectable leakage errors—-are a promising way to cut down the resources needed for quantum error correction. There have been several recent experiments demonstrating erasure qubits in superconducting quantum processors, most notably the dual-rail qubit defined by the one-photon subspace of two coupled cavities. An outstanding challenge is that the ancillary transmons needed to facilitate erasure checks and two-qubit gates introduce a substantial amount of noise, limiting the benefits of working with erasure-biased qubits. I will show how to suppress the adverse effects of transmon-induced noise while performing erasure checks or two-qubit gates. I will present control schemes for these operations that suppress erasure check errors by two orders of magnitude and reduce the logical two-qubit gate infidelities by up to three orders of magnitude. Starts at 12:00 p.m. ET/9:00 a.m. PT.
