Quantum Key Distribution over 100 km underwater optical fiber assisted by a Fast-Gated Single-Photon Detector
Domenico Ribezzo, Mujtaba Zahidy, Gianmarco Lemmi +10
Nowadays Quantum Key Distribution represents the most mature quantum technology, and multiple countries as well as private institutions are building their quantum network. However,…
DQC1 as an Open Quantum System
Jake Xuereb, Steve Campbell, John Goold +1
The DQC1 complexity class, or power of one qubit model, is examined as an open quantum system. We study the dynamics of a register of qubits carrying out a DQC1 algorithm and show…
Optomechanics for quantum technologies
Shabir Barzanjeh, André Xuereb, Simon Gröblacher +3
The ability to control the motion of mechanical systems through its interaction with light has opened the door to a plethora of applications in fundamental and applied physics. Wit…
Estimation of disorders in the rest positions of two membranes in optomechanical systems
Claudio Sanavio, József Zsolt Bernád, André Xuereb
The formalism of quantum estimation theory is applied to estimate the disorders in the positions of two membranes positioned in a driven cavity. We consider the coupled-cavities an…
Quantum Physics in Space
Alessio Belenchia, Matteo Carlesso, Ömer Bayraktar +17
Advances in quantum technologies are giving rise to a revolution in the way fundamental physics questions are explored at the empirical level. At the same time, they are the seeds…
Fisher-information-based estimation of optomechanical coupling strengths
Claudio Sanavio, József Zsolt Bernád, André Xuereb
The formalism of quantum estimation theory, focusing on the quantum and classical Fisher information, is applied to the estimation of the coupling strength in an optomechanical sys…
