Enriching the Quantum Toolbox of Ultracold Molecules with Rydberg Atoms

PRX Quantum, 2022
We describe a quantum information architecture consisting of a hybrid array of optically trapped molecules and atoms. This design leverages the large transition dipole moments of Rydberg atoms to mediate fast, high-fidelity gates between qubits encoded ...

A molecular mechanism for proton‐dependent gating in KcsA [PDF]

FEBS Letters, 2010
Activation gating in KcsA is elicited by changes in intracellular proton concentration. Thompson et al.[1] identified a charge cluster around the inner gate that plays a key role in defining proton activation in KcsA. Here, through functional and spectroscopic approaches, we confirmed the role of this charge cluster and now provide a mechanism of pH ...

Gated Nanosensor for Sulphate-Reducing Bacteria Detection

Nanomaterials
Desulfovibrio vulgaris is an anaerobic microorganism belonging to the group of sulphate-reducing bacteria (SRB). SRB form biofilms on metal surfaces in water supply networks, producing a microbiologically influenced corrosion (MIC). This process produces

Radiative Corrections and Quantum Gates in Molecular Systems [PDF]

Physical Review Letters, 2004
We propose a method for quantum information processing using molecules coupled to an external laser field. This utilizes molecular interactions, control of the external field and an effective energy shift of the doubly-excited state of two coupled molecules.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Calculation of Contraction Coefficient under Sluice Gates and Application to Discharge Measurement [PDF]

, 2009
The contraction coefficient under sluice gates on flat beds is studied for both free flow and submerged conditions based on the principle of momentum conservation, relying on an analytical determination of the pressure force exerted on the upstream face ...
