On-Demand Coherent Mapping of Telecom Optical States onto Erbium Hyperfine Spins
Zongfeng Li, Mahdi Hosseini
Optical quantum memories operating directly at telecom wavelengths are a key enabling technology for long-distance quantum networks, yet on-demand storage onto long-lived ground-st…
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…
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…
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…
Precision spectral manipulation: a demonstration using a coherent optical memory
B. M. Sparkes, C. Cairns, M. Hosseini +4
The ability to coherently spectrally manipulate quantum information has the potential to improve qubit rates across quantum channels and find applications in optical quantum comput…
Time- and frequency-domain polariton interference
G. T. Campbell, M. Hosseini, B. M. Sparkes +2
We present experimental observations of interference between an atomic spin coherence and an optical field in a Λ-type gradient echo memory. The interference is mediated by a stron…
An AC Stark Gradient Echo Memory in Cold Atoms
B. M. Sparkes, M. Hosseini, G. Hétet +2
The burgeoning fields of quantum computing and quantum key distribution have created a demand for a quantum memory. The gradient echo memory scheme is a quantum memory candidate fo…
Precision spectral manipulation of optical pulses using a coherent photon echo memory
B. C. Buchler, M. Hosseini, G. Hétet +2
Photon echo schemes are excellent candidates for high efficiency coherent optical memory. They are capable of high-bandwidth multi-pulse storage, pulse resequencing and have been s…
