Characterization of high-dimensional entangled systems via mutually unbiased measurements
D. Giovannini, J. Romero, J. Leach +3
Mutually unbiased bases (MUBs) play a key role in many protocols in quantum science, such as quantum key distribution. However, defining MUBs for arbitrary high-dimensional systems…
Non-linear optics using cold Rydberg atoms
J. D. Pritchard, K. J. Weatherill, C. S. Adams
The implementation of electromagnetically induced transparency (EIT) in a cold Rydberg gas provides an attractive route towards strong photon--photon interactions and fully determi…
Increasing the dimension in high-dimensional two-photon orbital angular momentum entanglement
J. Romero, D. Giovannini, S. Franke-Anold +2
Any practical experiment utilising the innate D-dimensional entanglement of the orbital angular momentum (OAM) state space of photons is subject to the modal capacity of the detect…
Determining the dimensionality of bipartite orbital-angular-momentum entanglement using multi-sector phase masks
D. Giovannini, F. M. Miatto, J. Romero +3
The Shannon dimensionality of orbital angular momentum (OAM) entanglement produced in spontaneous parametric down-conversion can be probed by using multi-sector phase analysers. We…
Grassmann Variables and the Jaynes-Cummings Model
Bryan J. Dalton, Barry M. Garraway, John Jeffers +1
This paper shows that phase space methods using a positive P type distribution function involving both c-number variables (for the cavity mode) and Grassmann variables (for the two…
Information communicated by entangled photon pairs
Thomas Brougham, Stephen M. Barnett
A key goal of quantum communication is to determine the maximum number of bits shared between two quantum systems. An important example of this is in entanglement based quantum key…
Securing a Quantum Key Distribution Network Using Secret Sharing
Stephen M. Barnett, Simon J. D. Phoenix
We present a simple new technique to secure quantum key distribution relay networks using secret sharing. Previous techniques have relied on creating distinct physical paths in ord…
Extending the Reach of QKD Using Relays
Stephen M. Barnett, Simon J. D. Phoenix
One of the obstacles to deployment of QKD solutions has been the distance limitation. Solutions using relays have been proposed but these rely on link-by-link key establishment. We…
Quantum system characterization with limited resources
Daniel Oi, Sophie Schirmer
The construction and operation of large scale quantum information devices presents a grand challenge. A major issue is the effective control of coherent evolution, which requires a…
Schmidt modes generated in parametric downconversion
Filippo M. Miatto, Henrique Di Lorenzo Pires, Stephen M. Barnett +1
This paper presents the general Schmidt decomposition of two-photon fields generated in spontaneous parametric down-conversion (SPDC). It discusses in particular the separation of…
