Quantum energetics of a non-commuting measurement
Xiayu Linpeng, Nicolò Piccione, Maria Maffei +5
When a measurement observable does not commute with a quantum system's Hamiltonian, the energy of the measured system is typically not conserved during the measurement. Instead, en…
Probing non-classical light fields with energetic witnesses in Waveguide Quantum Electro-Dynamics
Maria Maffei, Patrice A. Camati, Alexia Auffèves
We analyze energy exchanges between a qubit and a resonant field propagating in a waveguide. The joint dynamics is analytically solved within a repeated interaction model. The work…
Two-dimensional topological quantum walks in the momentum space of structured light
Alessio D'Errico, Filippo Cardano, Maria Maffei +7
Quantum walks are powerful tools for quantum applications and for designing topological systems. Although they are simulated in a variety of platforms, genuine two-dimensional real…
