If we could not find room for it, time to digest it, or a reason to run it during the past week, we have collected it here.  Not a recap for the week, but a cleanup of pieces we received and just could not get to. 

Because Quantum is Coming. Qubit.

Toshiba’s new algorithm seemingly leverages quantum computing while running on ordinary PCs | As any programmer will tell you, computational efficiency is the part and parcel of a good algorithm. And now, Toshiba, a renowned Japanese multinational conglomerate company, has claimed that it has created an algorithm that analyzes market data faster than even the most advanced supercomputers of today. The algorithm, dubbed “Simulated Bifurcation Algorithm”, leverages the principles of quantum computing⁠—despite running on traditional PCs⁠—to churn through market data to make certain calculations. Specifically, Toshiba has claimed that its new algorithm is capable of calculating arbitrage opportunities for currencies in a few microseconds only.  Source:  Neowin.  Ather Fawaz ,  Toshiba’s new algorithm seemingly leverages quantum computing while running on ordinary PCs …

Radio-frequency detected fast charge sensing in undoped silicon quantum dots. | Spin qubits in silicon quantum dots offer a promising platform for a quantum computer as they have a long coherence time and scalability. The charge sensing technique plays an essential role in reading out the spin qubit as well as tuning the device parameters and therefore its performance in terms of measurement bandwidth and sensitivity is an important factor in spin qubit experiments. Here we demonstrate fast and sensitive charge sensing by a radio-frequency reflectometry of an undoped, accumulation-mode Si/SiGe double quantum dot. We show that the large parasitic capacitance in typical accumulation-mode gate geometries impedes reflectometry measurements. We present a gate geometry that significantly reduces the parasitic capacitance and enables fast single-shot readout. The technique allows us to distinguish between the singly- and doubly-occupied two-electron states under the Pauli spin blockade condition in an integration time of 0.8 μs, the shortest value ever reported in silicon, by the signal-to-noise ratio of 6. These results provide a guideline for designing silicon spin qubit devices suitable for the fast and high-fidelity readout.  Source:  ACS Publications.  Akito Noiri, Kenta TakedaJun, YonedaTakashi, NakajimaTetsuo, KoderaSeigo Tarucha,  Radio-frequency detected fast charge sensing in undoped silicon quantum dots…
