Ions confined by surface-electrode Paul traps represent a promising technology for quantum computing and quantum simulation. In our group, the qubits are encoded in two hyperfine levels of 9Be+ ions and controlled by trap-integrated microwave conductors, which allow us to manipulate both the internal and motional states of the ions.
We will implement a cryogenic linear ion-trap array for eight ions with all electrical supplies necessary to apply microwave currents, DC- and RF-voltages. The trap array allows linear transport of ions, features independent storage zones and a detection register.
In addition, we will report on the status of the ongoing future-proof upgrade to the ARTIQ control system. This enables nanosecond timing pulse generation, radio-frequency synthesis and data acquisition executed on a dedicated FPGA hardware and interfaced with a Python-based programming language.
