Ultra-high bandwidth quantum secured data transmission

James F. Dynes, Winci W-S. Tam, Alan Plews +8

Quantum key distribution (QKD) provides an attractive means for securing communications in optical fibre networks. However, deployment of the technology has been hampered by the fr…

Near perfect mode overlap between independently seeded, gain-switched lasers

L. C. Comandar, M. Lucamarini, B. Fröhlich +3

We drastically improve the mode overlap between independently seeded, gain-switched laser diodes operating at gigahertz repetition rates by implementing a pulsed light seeding tech…

Quantum key distribution over multicore fiber

J. F. Dynes, S. J. Kindness, S. W. -B. Tam +7

We present the first quantum key distribution (QKD) experiment over multicore fiber. With space division multiplexing, we demonstrate that weak QKD signals can coexist with classic…

Quantum secured gigabit optical access networks

Bernd Fröhlich, James F. Dynes, Marco Lucamarini +4

Optical access networks connect multiple endpoints to a common network node via shared fibre infrastructure. They will play a vital role to scale up the number of users in quantum…

Efficient decoy-state quantum key distribution with quantified security

M. Lucamarini, K. A. Patel, J. F. Dynes +6

We analyse the finite-size security of the efficient Bennett-Brassard 1984 protocol implemented with decoy states and apply the results to a gigahertz-clocked quantum key distribut…

A quantum access network

Bernd Fröhlich, James F. Dynes, Marco Lucamarini +3

The theoretically proven security of quantum key distribution (QKD) could revolutionise how information exchange is protected in the future. Several field tests of QKD have proven…

A two-dimensional Fermi liquid with attractive interactions

B. Fröhlich, M. Feld, E. Vogt +4

We realize and study an attractively interacting two-dimensional Fermi liquid. Using momentum resolved photoemission spectroscopy, we measure the self-energy, determine the contact…

Radio frequency spectra of Feshbach molecules in quasi-two dimensional geometries

Stefan K. Baur, Bernd Fröhlich, Michael Feld +4

The line shape of radio frequency spectra of tightly bound Feshbach molecules in strong transverse confinement can be described by a simple analytic formula that includes final sta…

Attractive and repulsive Fermi polarons in two dimensions

Marco Koschorreck, Daniel Pertot, Enrico Vogt +3

The dynamics of a single impurity in an environment is a fundamental problem in many-body physics. In the solid state, a well-known case is an impurity coupled to a bosonic bath, f…

Observation of a pairing pseudogap in a two-dimensional Fermi gas

Michael Feld, Bernd Fröhlich, Enrico Vogt +2

Pairing of fermions is ubiquitous in nature and it is responsible for a large variety of fascinating phenomena like superconductivity, superfluidity of He, the anomalous rotati…

Scale invariance and viscosity of a two-dimensional Fermi gas

Enrico Vogt, Michael Feld, Bernd Fröhlich +3

We investigate the collective excitations of a harmonically trapped two-dimensional Fermi gas from the collisionless (zero sound) to the hydrodynamic (first sound) regime. The brea…

A purely dipolar quantum gas

T. Lahaye, J. Metz, T. Koch +3

We report on experiments exploring the physics of dipolar quantum gases using a Chromium Bose-Einstein condensate (BEC). By means of a Feshbach resonance, it is possible to reduce…
