Microwave spectroscopy of radio-frequency dressed 87Rb (2019)
Journal Article
A. Sinuco-Leon, G., M. Garraway, B., Mas, H., Pandey, S., Vasilakis, G., Bolpasi, V., …Fernholz, T. (2019). Microwave spectroscopy of radio-frequency dressed 87Rb. Physical Review A, 100(5), https://doi.org/10.1103/PhysRevA.100.053416

We study the hyperfine spectrum of atoms of $^{87}$Rb dressed by a radio-frequency field, and present experimental results in three different situations: freely falling atoms, atoms trapped in an optical dipole trap and atoms in an adiabatic radio-fr...

Ring-shaped atom-trap lattices using multipole dressing fields (2019)
Journal Article
Gentile, F., Johnson, J., Poulios, K., & Fernholz, T. Ring-shaped atom-trap lattices using multipole dressing fields. Manuscript submitted for publication

We present a method for the creation of closed-loop lattices for ultra-cold atoms using dressed potentials. We analytically describe the generation of trap lattices that are state-dependent, with dynamically controlled lattice depths and positioning....

Matter-wave interferometers using TAAP rings (2016)
Journal Article
Navez, P., Pandey, S., Mas, H., Poulios, K., Fernholz, T., & von Klitzing, W. (in press). Matter-wave interferometers using TAAP rings. New Journal of Physics, 18, doi:10.1088/1367-2630/18/7/075014

We present two novel matter-wave Sagnac interferometers based on ring-shaped time-averaged adiabatic potentials (TAAP). For both the atoms are put into a superposition of two different spin states and manipulated independently using elliptically pola... Read More about Matter-wave interferometers using TAAP rings.

Quantum Logic with Cavity Photons from Single Atoms (2016)
Journal Article
Holleczek, A., Barter, O., Rubenok, A., Dilley, J., Nisbet-Jones, P. B., Langfahl-Klabes, G., …Matthews, J. C. (2016). Quantum Logic with Cavity Photons from Single Atoms. Physical Review Letters, 117(2), https://doi.org/10.1103/PhysRevLett.117.023602

© 2016 American Physical Society. We demonstrate quantum logic using narrow linewidth photons that are produced with an a priori nonprobabilistic scheme from a single Rb87 atom strongly coupled to a high-finesse cavity. We use a controlled-not gate i... Read More about Quantum Logic with Cavity Photons from Single Atoms.

Towards rotation sensing with a single atomic clock (2016)
Journal Article
Mas, H., Lesanovsky, I. V., Fernholz, T., Stevenson, R., Hush, M. R., Lesanovsky, I., …von Klitzing, W. (2016). Towards rotation sensing with a single atomic clock. Proceedings of SPIE, 9900(990007), https://doi.org/10.1117/12.2229878

We discuss a scheme to implement a gyroscopic atom sensor with magnetically trapped ultra-cold atoms. Unlike standard light or matter wave Sagnac interferometers no free wave propagation is used. Interferometer operation is controlled only with stati... Read More about Towards rotation sensing with a single atomic clock.

Quantum Walks of Correlated Photon Pairs in Two-Dimensional Waveguide Arrays (2014)
Journal Article
Poulios, K., Keil, R., Fry, D., D. A. Meinecke, J., C. F. Matthews, J., Politi, A., …L. O'Brien, J. (2014). Quantum Walks of Correlated Photon Pairs in Two-Dimensional Waveguide Arrays. Physical Review Letters, 112(14), https://doi.org/10.1103/PhysRevLett.112.143604

We demonstrate quantum walks of correlated photons in a 2D network of directly laser written waveguides coupled in a 'swiss cross' arrangement. The correlated detection events show high-visibility quantum interference and unique composite behaviour:...

Coherent time evolution and boundary conditions of two-photon quantum walks in waveguide arrays (2013)
Journal Article
D. A. Meinecke, J., Poulios, K., Politi, A., C. F. Matthews, J., Peruzzo, A., Ismail, N., …G. Thompson, M. (2013). Coherent time evolution and boundary conditions of two-photon quantum walks in waveguide arrays. Physical Review A, 88(1), https://doi.org/10.1103/PhysRevA.88.012308

Multi-photon quantum walks in integrated optics are an attractive controlled quantum system, that can mimic less readily accessible quantum systems and exhibit behavior that cannot in general be accurately replicated by classical light without an exp...

Observing fermionic statistics with photons in arbitrary processes (2013)
Journal Article
C. F. Matthews, J., Poulios, K., D. A. Meinecke, J., Politi, A., Peruzzo, A., Ismail, N., …L. O'Brien, J. (2013). Observing fermionic statistics with photons in arbitrary processes. Scientific Reports, 3, https://doi.org/10.1038/srep01539

In contrast to classical physics, quantum mechanics divides particles into two classes-bosons and fermions-whose exchange statistics dictate the dynamics of systems at a fundamental level. In two dimensions quasi-particles known as 'anyons' exhibit f... Read More about Observing fermionic statistics with photons in arbitrary processes.
