Hybrid quantum logic and a test of Bell's inequality using two different atomic isotopes

C. J. Ballance, V. M. Schaefer, J. P. Home +9

Entanglement is one of the most fundamental properties of quantum mechanics, and is the key resource for quantum information processing. Bipartite entangled states of identical par…

Experimental recovery of a qubit from partial collapse

J. A. Sherman, M. J. Curtis, D. J. Szwer +4

We describe and implement a method to restore the state of a single qubit, in principle perfectly, after it has partially collapsed. The method resembles the classical Hahn spin-ec…

Storage and control of optical photons using Rydberg polaritons

D. Maxwell, D. J. Szwer, D. P. Barato +6

We use a microwave field to control the quantum state of optical photons stored in a cold atomic cloud. The photons are stored in highly excited collective states (Rydberg polarito…

Background-free detection of trapped ions

N. M. Linke, D. T. C. Allcock, D. J. Szwer +6

We demonstrate a Doppler cooling and detection scheme for ions with low-lying D levels which almost entirely suppresses scattered laser light background, while retaining a high flu…

Implementation of a symmetric surface electrode ion trap with field compensation using a modulated Raman effect

D. T. C. Allcock, J. A. Sherman, D. N. Stacey +8

We describe the fabrication and characterization of a new surface-electrode Paul ion trap designed for experiments in scalable quantum information processing with Ca+. A notable fe…

Scalable simultaneous multi-qubit readout with 99.99% single-shot fidelity

A. H. Burrell, D. J. Szwer, S. C. Webster +1

We describe single-shot readout of a trapped-ion multi-qubit register using space and time-resolved camera detection. For a single qubit we measure 0.9(3)x10^{-4} readout error in…
