Continuous-variable entanglement distillation and non-commutative central limit theorems
Earl T. Campbell, Marco G. Genoni, Jens Eisert
Entanglement distillation transforms weakly entangled noisy states into highly entangled states, a primitive to be used in quantum repeater schemes and other protocols designed for…
Recursive quantum detector tomography
L. Zhang, A. Datta, H. B. Coldenstrodt-Ronge +4
Conventional tomographic techniques are becoming increasingly infeasible for reconstructing the operators of quantum devices of growing sophistication. We describe a novel tomograp…
Quantum Tomography via Compressed Sensing: Error Bounds, Sample Complexity, and Efficient Estimators
Steven T. Flammia, David Gross, Yi-Kai Liu +1
Intuitively, if a density operator has small rank, then it should be easier to estimate from experimental data, since in this case only a few eigenvectors need to be learned. We pr…
Single ion heat engine with maximum efficiency at maximum power
Obinna Abah, Johannes Rossnagel, Georg Jacob +4
We propose an experimental scheme to realize a nano heat engine with a single ion. An Otto cycle may be implemented by confining the ion in a linear Paul trap with tapered geometry…
Null Values and Quantum State Discrimination
Oded Zilberberg, Alessandro Romito, David J. Starling +4
We present a measurement protocol for discriminating between two different quantum states of a qubit with high fidelity. The protocol, called null value, is comprised of a projecti…
Magic state distillation in all prime dimensions using quantum Reed-Muller codes
Earl T. Campbell, Hussain Anwar, Dan E. Browne
We propose families of protocols for magic state distillation -- important components of fault tolerance schemes --- for systems of odd prime dimension. Our protocols utilize quant…
