Quantum fingerprinting using two-photon interference
Michał Jachura, Michał Lipka, Marcin Jarzyna +1
We present a quantum fingerprinting protocol relying on two-photon interference which does not require a shared phase reference between the parties preparing optical signals carryi…
Visibility-based hypothesis testing using higher-order optical interference
Michał Jachura, Marcin Jarzyna, Michał Lipka +2
Many quantum information protocols rely on optical interference to compare datasets with efficiency or security unattainable by classical means. Standard implementations exploit fi…
On superresolution imaging as a multiparameter estimation problem
Andrzej Chrostowski, Rafal Demkowicz-Dobrzanski, Marcin Jarzyna +1
We consider the problem of characterising the spatial extent of a composite light source using the superresolution imaging technique when the centroid of the source is not known pr…
Efficiency of Optimized Pulse Position Modulation with Noisy Direct Detection
Marcin Jarzyna, Konrad Banaszek
We analyze theoretically the impact of background counts on the efficiency of optical communication in the photon-starved regime using the pulse position modulation (PPM) format wi…
Optimal lossy quantum interferometry in phase space
Andrei B. Klimov, Marcin Zwierz, Sascha Wallentowitz +2
We analyse the phase space representation of the optimal measurement of a phase shift in an interferometer with equal photon loss in both its arms. In the local phase estimation sc…
Classical capacity per unit cost for quantum channels
Marcin Jarzyna
In most communication scenarios, sending a symbol encoded in a quantum state requires spending resources such as energy, which can be quantified by a cost of communication. A stand…
