Electronic quantum gates
Trapped ion quantum computers generally use pairs of laser beams aligned to the position of individual ions to execute quantum gates. This requires alignment accuracy to a fraction of the width of a human hair. But imagine trying to align millions of laser beams with such incredible accuracy, while stabilising each one’s power, position and phase – where the slightest deviation stops the quantum computer from working.
We use a much simpler electronic gate technology where a combination of voltages is applied to our microchip.
The best part of this gate scheme is that it doesn’t matter if we have ten or ten million qubits, the number of microwave sources is fixed allowing for dramatically simplified scaling.
