This research introduces a monolithic printed-circuit board design for linear Paul traps, aiming to simplify the fabrication of electron-spin qubits by eliminating complex assembly processes. The study demonstrates significant engineering progress with trapped electron lifetimes exceeding 2 ms and secular frequencies reaching up to 90 MHz on a single rigid substrate. This hardware advancement directly addresses scalability challenges in quantum information processing platforms that rely on trapped electrons rather than ions or superconducting circuits.
Monolithic printed-circuit board RF-trap for electrons
arXiv:2607.18401v1 Announce Type: new Abstract: Qubits encoded in the spin of trapped electrons have been proposed as a promising novel platform for quantum information processing. While trapping of electrons has been largely carried out in Penning traps for precision measurement purposes, it is desirable to use linear Paul traps instead, leaning on the successes of trapped ion quantum processors. Here we present a Paul trap for electrons made of a single printed circuit board. Our approach requires no assembly and the rigid design minimizes manufacturing intolerances. We characterize the trap performance and observe trapped electron lifetimes of 2.13 ms and secular frequencies of up to 90 MHz.
