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…
Practicality of spin chain 'wiring' in diamond quantum technologies
Yuting Ping, Brendon W. Lovett, Simon C. Benjamin +1
Coupled spin chains are promising candidates for 'wiring up' qubits in solid-state quantum computing (QC). In particular, two nitrogen-vacancy centers in diamond can be connected b…
How general are time-local master equations?
Daniel Maldonado-Mundo, Patrik Ohberg, Brendon W. Lovett +1
Time-local master equations are more generally applicable than is often recognised, but at first sight it would seem that they can only safely be used in time intervals where the t…
Entanglement control via reservoir engineering in ultracold atomic gases
Suzanne McEndoo, Pinja Haikka, Gabriele de Chiara +2
We study the entanglement of two impurity qubits immersed in a Bose-Einstein condensate (BEC) reservoir. This open quantum system is particularly interesting because the reservoir…
Non-Markovian waiting time distribution
Kimmo Luoma, Kari Härkönen, Sabrina Maniscalco +2
Simulation methods based on stochastic realizations of state vector evolutions are commonly used tools to solve open quantum system dynamics, both in the Markovian and non-Markovia…
Entanglement trapping in a non-stationary structured reservoir
C. Lazarou, K. Luoma, S. Maniscalco +2
We study a single two-level atom interacting with a reservoir of modes defined by a reservoir structure function with a frequency gap. Using the pseudomodes technique, we derive th…
