Scaling of ions trap quantum computer is difficult. This is because as the number of trapped ions for computing is increased
Answers
Answer:
The two phases of a typical trapped ion experiment are performed with the following tools:
Qubit control (preparation and gate operations): The UHF Arbitrary Waveform Generator generates RF pulses at multiple phase-coherent frequencies and 32-channel TTL signals with precise timing. RF pulses drive acousto-optic modulators (AOMs) or trap electrodes, whereas TTL signals address RF switching and gain stages.
Qubit readout: The UHF-CNT Pulse Counter analyzes a photomultiplier tube output signal.
Both tools are fully integrated into the LabOne user interface and support easy integration into LabVIEW, Python, and Matlab. Internal cross-domain triggering simplifies the synchronization of preparation and measurement phase, and open the possibility to perform ultra-fast feed-forward protocols for deterministic qubit reset and quantum error correction.
Trapped Ion Setup
Ions are kept floating in vacuum by an electromagnetic trap. RF Pulses generated by the AWG are directed to AOMs which deflect and modulate laser beams. In the measurement phase, light scattered by the ions is collected by a lens and detected with photomultiplier tube.
