Two-way Gaussian quantum cryptography against coherent attacks in direct reconciliation
Carlo Ottaviani, Stefano Mancini, Stefano Pirandola
We consider the two-way quantum cryptographic protocol with coherent states assuming direct reconciliation. A detailed security analysis is performed considering a two-mode coheren…
Measurement uncertainty relations: characterising optimal error bounds for qubits
Tom Bullock, Paul Busch
In standard formulations of the uncertainty principle, two fundamental features are typically cast as impossibility statements: two noncommuting observables cannot in general both…
Quantum communications and quantum metrology in the spacetime of a rotating planet
Jan Kohlrus, David Edward Bruschi, Jorma Louko +1
We study how quantum systems that propagate in the spacetime of a rotating planet are affected by the curved background. Spacetime curvature affects wavepackets of photons propagat…
Ultimate precision: Gaussian parameter estimation in flat and curved spacetime
Dominik Šafránek, Jan Kohlrus, David Edward Bruschi +2
Relativistic quantum metrology provides an optimal strategy for the estimation of parameters encoded in quantum fields in flat and curved spacetime. These parameters usually corres…
Fundamental Limits of Repeaterless Quantum Communications
Stefano Pirandola, Riccardo Laurenza, Carlo Ottaviani +1
Quantum communications promises reliable transmission of quantum information, efficient distribution of entanglement and generation of completely secure keys. For all these tasks,…
Mutually Unbiased Product Bases for Multiple Qudits
Daniel McNulty, Bogdan Pammer, Stefan Weigert
We investigate the interplay between mutual unbiasedness and product bases for multiple qudits of possibly different dimensions. A product state of such a system is shown to be mut…
