Towards a Scalable quantum computing platform with trapped electrons in Paul Traps

We are working towards realizing a scalable quantum computing platform using spins of electrons as qubits. Among the different physical implementations, trapped electrons offer high clock speeds in the GHz regime and are expected to offer coherence times on the minute scale, similar to qubits in trapped ions. Moreover, the electron's simple two-level structure avoids information leakage to other states. Our recent feasibility study of a quantum processor based on trapped electrons shows that error rates of less than 1e-4 in two-qubit gate operations are theoretically achievable.

Here we report on our progress to set up a 3d-printed miniaturized Paul trap for electrons in a cryogenic environment and discuss our path towards implementing non-destructive state readout and two-qubit gate operations.
