Bosonic quantum communication beyond the thermal threshold
Francesco Anna Mele, Giuseppe Catalano, Marco Fanizza +2
The paper proves that non‑Gaussian input states can achieve a positive quantum capacity for bosonic thermal attenuator channels in regimes where Gaussian inputs give zero coherent…
A resource-efficient quantum-walker Quantum RAM
Giuseppe De Riso, Giuseppe Catalano, Seth Lloyd +2
Efficient and coherent data retrieval and storage are essential for harnessing quantum algorithms' speedup. Such a fundamental task is addressed by a quantum Random Access Memory (…
Controlling Sloppiness in Two-Phase Estimation with a Tunable Weak Measurement
Gabriele Bizzarri, Miranda Parisi, Mylenne Manrique +6
The description of complex systems requires a progressively larger number of parameters. However, in practice, it often happens that a small subset of parameters suffices to descri…
Statistical Characterization of Entanglement Degradation Under Markovian Noise in Composite Quantum Systems
Nunzia Cerrato, Sauro Succi, Giacomo De Palma +1
Understanding how noise degrades entanglement is crucial for the development of reliable quantum technologies. While the Markovian approximation simplifies the analysis of noise, i…
A quantum algorithm for estimating the determinant
Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone
We present a quantum algorithm for estimating the matrix determinant based on quantum spectral sampling. The algorithm estimates the logarithm of the determinant of an …
Extracting energy via bosonic Gaussian operations
Frank Ernesto Quintela Rodriguez, Francesco Anna Mele, Salvatore Francesco Emanuele Oliviero +3
Quantum thermodynamics is often formulated as a theory with constrained access to operations and resources. In this manuscript, we find a closed formula for the Gaussian ergotropy,…
