Integrated photonics for trapped ion quantum information

Trapped-ion quantum information processors continue to scale towards greater I/O, size, and power requirements in the push to control more ions. These demands motivate the replacement of external optical infrastructure like detectors, beam splitters and modulators with integrated versions. Full integration with an ion trap allows for both greater numbers of qubits as well as better control of quantum operations. We present the latest results at Sandia National Laboratories involving monolithically-integrated photonics with surface traps[1,2].
