Abstract
We demonstrate a surface-electrode ion trap fabricated using techniques transferred from the manufacture of photonic-crystal fibres. This provides a relatively straightforward route for realizing traps with an electrode structure on the 100 micron scale with high optical access. We demonstrate the basic functionality of the trap by cooling a single ion to the quantum ground state, allowing us to measure a heating rate from the ground state of 787 ± 24 quanta/s. Variation of the fabrication procedure used here may provide access to traps in this geometry with trap scales between 100 μm and 10 μm.
Highlights
Trapped atomic ions are among the best experimental systems for quantum computation, quantum simulation, and atomic frequency standards.[1]

Summary
Trapped atomic ions are among the best experimental systems for quantum computation, quantum simulation, and atomic frequency standards.[1] Ion traps in use today span from those fabricated using precision machining to microfabricated structures formed using photo-lithographic techniques. The latter offers potential advantages in the context of minituarization due to high precision of manufacture and can potentially be used for more complex, larger scale systems following techniques transferred from the microelectronics industry.[2,3] Creating an interface between trapped ions and optical fields is a key component of proposals for scalable quantum computation and communication.[4,5,6] One approach has been to integrate optical fibres into a dedicated trap structure.[7,8,9,10,11,12] We take the opposite route and present an ion trap which takes advantages of the early steps in the production of photonic-crystal-fibres (PCFs) to realize a surface electrode trap This provides a simple fabrication process for traps at the 100 micron scale. Extensions of our technique may allow for traps with integrated PCFs or trap arrays suitable for quantum simulation of 2-dimensional lattices.[13,14]
