Direct comparisons of European primary and secondary frequency standards via satellite techniques
F. Riedel, A. Al-Masoudi, E. Benkler +46
We carried out a 26-day comparison of five simultaneously operated optical clocks and six atomic fountain clocks located at INRIM, LNE-SYRTE, NPL and PTB by using two satellite-bas…
Compact laser system for a laser-cooled ytterbium ion microwave frequency standard
S. Mulholland, H. A. Klein, G. P. Barwood +6
The development of a transportable microwave frequency standard based on the ground-state transition of at ~12.6 GHz requires a compact laser system for coo…
Multimode interferometry for entangling atoms in quantum networks
Thomas D. Barrett, Allison Rubenok, Dustin Stuart +10
We bring together a cavity-enhanced light-matter interface with a multimode interferometer (MMI) integrated onto a photonic chip and demonstrate the potential of such hybrid system…
Measurement of differential polarizabilities at a mid-infrared wavelength in
C F A Baynham, E A Curtis, R M Godun +10
An atom exposed to an electric field will experience Stark shifts of its internal energy levels, proportional to their polarizabilities. In optical frequency metrology, the Stark s…
Absolute frequency measurement of the SF optical clock transition in Yb with an uncertainty of using a frequency link to International Atomic Time
Charles F. A. Baynham, Rachel M. Godun, Jonathan M. Jones +8
The highly forbidden SF electric octupole transition in Yb is a potential candidate for a redefinition of the SI second. We present a…
A Single-Ion Trap with Minimized Ion-Environment Interactions
P. B. R. Nisbet-Jones, S. A. King, J. M. Jones +6
We present a new single-ion endcap trap for high precision spectroscopy that has been designed to minimize ion-environment interactions. We describe the design in detail and then c…
Photonic Quantum Logic with Narrowband Light from Single Atoms
Annemarie Holleczek, Oliver Barter, Allison Rubenok +9
Increasing control of single photons enables new applications of photonic quantum-enhanced technology and further experimental exploration of fundamental quantum phenomena. Here, w…
Frequency comparison of Yb ion optical clocks at PTB and NPL via GPS PPP
J. Leute, N. Huntemann, B. Lipphardt +11
We used Precise Point Positioning, a well-established GPS carrier-phase frequency transfer method to perform a direct remote comparison of two optical frequency standards based on…
Photonic qubits, qutrits and ququads accurately prepared and delivered on demand
Peter B. R. Nisbet-Jones, Jerome Dilley, Annemarie Holleczek +2
Reliable encoding of information in quantum systems is crucial to all approaches to quantum information processing or communication. This applies in particular to photons used in l…
Highly Efficient Source for Indistinguishable Photons of Controlled Shape
Peter Nisbet, Jerome Dilley, Axel Kuhn
We demonstrate a straightforward implementation of a push-button like single-photon source which is based on a strongly coupled atom-cavity system. The device operates intermittent…
Single-Photon Absorption in Coupled Atom-Cavity Systems
Jerome Dilley, Peter Nisbet-Jones, Bruce W. Shore +1
We show how to capture a single photon of arbitrary temporal shape with one atom coupled to an optical cavity. Our model applies to Raman transitions in three-level atoms with one…
