The Argonne team focused on using a single electron as a qubit. Heating a light bulb filament emits a stream of electrons, but qubits are very sensitive to disturbances from the surrounding environment. To get around this problem, the researchers trapped an electron on an ultrapure solid neon s...
Light Bulb Efficiency The efficiency of LEDs and other light sources is measured in lumens per Watt, and this can often be found on the packaging of LED light bulbs. On the packaging, it is usually on the back written something like this: ’88 lm/W). That’s 88 lumens of light per ...
