Expressivity of Quantum Reservoir Computers
Nils-Erik Schütte, Niclas Götting, Hauke Müntinga +3
Using Hamiltonian encoding to inject an input into parameterized quantum circuits (PQCs), the output of the PQC can be written as truncated Fourier series. In recent years, the exp…
Memory-Nonlinearity Trade-off across Quantum Reservoir Computing Frameworks
Saud Äindrak, Lara Giebeler, Niclas Götting +2
Quantum reservoir computing (QRC) harnesses driven quantum dynamics for time-series processing, yet the mechanisms behind the differing performance levels across its many implement…
Timing quantum emission: coherence, superradiance, and entanglement in order
Nur Fadhillah Binti Rahimi, Norman Koo Tze Wei, Daniel Schumayer +3
We investigate the short-term temporal dynamics of superradiance in closely spaced quantum emitters. Building on Dicke's 1954 framework, we analyze the sequential emergence of cohe…
Tunable WS Micro-Dome Open Cavity Single Photon Source
Jens-Christian Drawer, Salvatore Cianci, Vita Solovyeva +13
Versatile, tunable, and potentially scalable single-photon sources are a key asset in emergent photonic quantum technologies. In this work, a single-photon source based on WS m…
Connection between memory performance and optical absorption in quantum reservoir computing
Niclas Götting, Steffen Wilksen, Alexander Steinhoff +2
The fading memory property is a key requirement for reservoir computers -- a specific type of recurrent neural network with fixed internal weights. While mostly undesired in gate-b…
Harnessing Photon Indistinguishability in Quantum Extreme Learning Machines
Malo Joly, Adrian Makowski, Baptiste Courme +6
Recent advancements in machine learning have led to an exponential increase in computational demands, driving the need for innovative computing platforms. Quantum computing, with i…
