The authors measure the splitting of single Cooper pairs by microwave photons, and their recombination, in a new type superconducting double quantum dot. They envisage single-photon detector based on physical principles involved.
We study the energetics of a superconducting double dot, by measuring both quantum capacitance device and response nearby charge sensor. observe different behaviour for odd even states describe this with model based on competition between charging energy gap. also find that, at finite temperatures, thermodynamic considerations have significant effect stability diagram.
The detection of single microwave photons remains a difficult challenge because their low energy. authors demonstrate that an aluminum superconducting double dot can be tuned to regime in which photon creating quasiparticle pair changes the quantum capacitance device. By using high-bandwidth reflectometry techniques, they observe absorption real time. They also exploit band structure device tune frequencies it is sensitive and use this carry out spectroscopy on ambient black-body radiation...
We report an improved synthesis of the NON-donor stabilized potassium gallyl dimer [K{Ga(NON)}]2 (NON = 4,5-bis(2,6-diisopropylanilido)-2,7-di-tert-butyl-9,9-dimethyl-xanthene) from (NON)GaI and naphthalenide that avoids issues associated with over-reduction metal centre. The use in Ga–E bonds has been explored through its reactions a range electrophiles. reaction to give {Ga(NON)}2 via Ga–Ga bond formation mirrors behaviour corresponding aluminyl compound, while Ga–C nucleophilic attack on...
We use an artificial neural network to analyze asymmetric noisy random telegraph signals, and extract underlying transition rates. demonstrate that a long short-term memory can outperform other methods, particularly for signals measurements with limited bandwidths. Our technique gives reliable results as the signal-to-noise ratio approaches one, over wide range of apply our method generated by quasiparticle poisoning in superconducting double dot, allowing us extend measurement dynamics new...
A metallic double dot is measured with radio frequency reflectometry. Changes in the total electron number of are determined via single tunnelling contributions to complex electrical impedance. Electron counting experiments performed by monitoring impedance, demonstrating operation a ammeter without need for external charge detection.

A measurement of the time‐resolved emission transient X‐ray laser pulses is described. An ultra‐fast X‐UV streak camera set at focal plane a flat field Spectrometer was used to obtain temporal evolution spectra Ni‐like Ag and Ne‐like Ni plasmas in small wavelength range covering lasing lines.
