Structured Optical Receivers for Efficient Deep-Space Communication
Konrad Banaszek, Michał Jachura
We discuss conceptual designs for structured optical receivers that can alleviate the requirement for high peak-to-average power ratio in photon-starved optical communication. The…
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…
Measurement of radio-frequency temporal phase modulation using spectral interferometry
Michał Jachura, Jan Szczepanek, Wojciech Wasilewski +1
We present an optical method to measure radio-frequency electro-optic phase modulation profiles by employing spectrum-to-time mapping realized by highly chirped optical pulses. We…
Generation and characterization of discrete spatial entanglement in multimode nonlinear waveguides
Michał Jachura, Michał Karpiński, Konrad Banaszek +3
We analyze theoretically spontaneous parametric down-conversion in a multimode nonlinear waveguide as a source of entangled pairs of spatial qubits, realized as superpositions of a…
