The Heisenberg uncertainty principle, however, imposes a trade-off between speed and thermodynamic cost. The so-called quantum speed limits constrain the maximum performance of any quantum device by establishing an upper limit on the rate of state evolution within finite energy constraints17,18,19,...
the quantum sensor detects the phase of a backscattered RF signal through an RF interferometer. The concept is shown in Fig.1a. The signal from a RF generator is split into two individual paths, which are subsequently radiated into free
Solid-state display cells based on fluoride electrolytes have been fabricated. Finally, it has been shown that, in principle, electrochromic display cells can be intrinsically matrix-addressed. select article Electrochemical intercalation of sodium in NaxCoO2 bronzes Research articleAbstract only Electroche...
Measurement, or readout, allows information to be gained from a quantum system, but in accordance with the uncertainty principle, also disturbs it in proportion to the amount of information extracted.13 Unlike in classical physics, quantum mechanics prevents the state of a qubit from being ...
A waveform increasing approximately linearly as a function of time for a fixed interval, returning to its original state sharply, and repeating the process periodically. sawtooth current A current that has a sawtooth waveform. sawtooth generator An oscillator providing an alternating voltage with a saw...
Spanning a range of hardware platforms, the building-blocks of quantum processors are today sufficiently advanced to begin work on scaling-up these systems into complex quantum machines. A key subsystem of all quantum machinery is the interface between t
In this work, we report a quasi-solid-state anode-free cell with high energy and reliability enabled by applying Li-rich, oxygen-free Li2S cathode in a robust composite gel polymer electrolyte (CGPE) with fast ion transport, good thermal stability and fire retardance (Fig.1). The redox ac...
A coiled-up thermoelectric micro power generator is presented using metal films sputtered on a thin polyimide foil. The principle of coiling-up yields higher voltages at a smaller generator area. Design optimizations were made for maximum long-term power output using the human body as heat source...
The principle of the sensor is described and its pressure range [10−3 Pa – atmospheric pressure] is compared to the state of the art. The fabrication process is described as well as the sensor integration on a printed circuit board. The SAW device is a delay line with a frequency ...
