High-efficiency cold-atom transport into a waveguide trap
Ashby P. Hilton, Christopher Perrella, Fetah Benabid +3
We have developed and characterized an atom-guiding technique that loads cold rubidium atoms into hollow-core optical fibre, an order-of-magnitude larger than previou…
Dual-rail optical gradient echo memory
Daniel B. Higginbottom, Jiao Geng, Geoff T. Campbell +7
We introduce a scheme for the parallel storage of frequency separated signals in an optical memory and demonstrate that this dual-rail storage is a suitable memory for high fidelit…
Single-Shot Electron Diffraction using a Cold Atom Electron Source
Rory W. Speirs, Corey T. Putkunz, Andrew J. McCulloch +3
Cold atom electron sources are a promising alternative to traditional photocathode sources for use in ultrafast electron diffraction due to greatly reduced electron temperature at…
Unconditional Room Temperature Quantum Memory
M. Hosseini, G. Campbell, B. M. Sparkes +2
Just as classical information systems require buffers and memory, the same is true for quantum information systems. The potential that optical quantum information processing holds…
Electromagnetically induced transparency and four-wave mixing in a cold atomic ensemble with large optical depth
J. Geng, G. T. Campbell, J. Bernu +7
We report on the delay of optical pulses using electromagnetically induced transparency in an ensemble of cold atoms with an optical depth exceeding 500. To identify the regimes in…
Gradient echo memory in an ultra-high optical depth cold atomic ensemble
B. M. Sparkes, J. Bernu, M. Hosseini +6
Quantum memories are an integral component of quantum repeaters - devices that will allow the extension of quantum key distribution to communication ranges beyond that permissible…
Experimental Investigation of the Transition between Autler-Townes Splitting and Electromagnetically-Induced Transparency
L. Giner, L. Veissier, B. Sparkes +10
Two phenomena can affect the transmission of a weak signal field through an absorbing medium in the presence of a strong additional field: electromagnetically induced transparency…
Storage and Manipulation of Light Using a Raman Gradient Echo Process
M. Hosseini, B. M. Sparkes, G. T. Campbell +2
The Gradient Echo Memory (GEM) scheme has potential to be a suitable protocol for storage and retrieval of optical quantum information. In this paper, we review the properties of t…
Memory-Enhanced Noiseless Cross Phase Modulation
M. Hosseini, S. Rebic, B. M. Sparkes +3
Using a gradient echo memory, we experimentally demonstrate cross phase modulation (XPM) between two optical pulses; one stored and one freely propagating through the memory medium…
High efficiency coherent optical memory with warm rubidium vapour
M. Hosseini, B. M. Sparkes, G. Campbell +2
By harnessing aspects of quantum mechanics, communication and information processing could be radically transformed. Promising forms of quantum information technology include optic…
Photon echoes generated by reversing magnetic field gradients in a rubidium vapour
G. Hétet, M. Hosseini, B. M. Sparkes +3
We propose a photon echo quantum memory scheme using detuned Raman coupling to long lived ground states. In contrast to previous 3-level schemes based on controlled reversible inho…
