CHEMISTRY: Catch, Kill, and Release

Catch and Release of Photons

Information and communication technologies continue to revolutionize our modern societies. Further transformation may come from quantum technologies, which are still in their infancy but offer the possibility to process information more efficiently or to communicate more securely than any conceivable classical technology could. People are already dreaming of a quantum internet [1] that would co...

Scheduling Chemotherapy: Catch 22 between Cell Kill and Resistance Evolution

Dose response curves show that prolonged drug exposure at a low concentration may kill more cells than short exposures at higher drug concentrations, particularly for cell cycle phase specific drugs. Applying drugs at low concentrations for prolonged periods, however, allows cells with partial resistance to evolve higher levels of resistance through stepwise processes such as gene amplification...

Catch Me Before I Kill More: Seriality as Modern Monstrosity

Catch and release of microwave photon states.

We demonstrate a superconducting resonator with variable coupling to a measurement transmission line. The resonator coupling can be adjusted through zero to a photon emission rate 1000 times the intrinsic resonator decay rate. We demonstrate the catch and release of photons in the resonator, as well as control of nonclassical Fock states. We also demonstrate the dynamical control of the release...

Catch-disperse-release readout for superconducting qubits.

We analyze a single-shot readout for superconducting qubits via the controlled catch, dispersion, and release of a microwave field. A tunable coupler is used to decouple the microwave resonator from the transmission line during the dispersive qubit-resonator interaction, thus circumventing damping from the Purcell effect. We show that, if the qubit frequency tuning is sufficiently adiabatic, a ...
