Energetics of non-Gaussianity in single mode cavities
Sahil Sardar Jafar, Kian Hwee Lim, Kiarn T. Laverick +3
Non-Gaussian states play a central role in quantum technologies, making the ability to quantify non-Gaussianity essential. We introduce an energetic framework to characterize non-G…
Optimizing Wigner Negativity in Scattering Processes Using Energetic Cost Functions
Kian Hwee Lim, Kiarn T. Laverick, Sahil Sardar Jafar +3
Wigner negativities (WNs) are key signatures of non-Gaussian bosonic states and essential resources for quantum technologies. We study their generation in the scattering of coheren…
An Energetic Constraint for Qubit-Qubit Entanglement
Kiarn T. Laverick, Samyak P. Prasad, Pascale Senellart +2
We analyze qubit-qubit entanglement from an energetic perspective and reveal an energetic trade-off between quantum coherence and entanglement. We decompose each qubit internal ene…
Thermodynamics of autonomous optical Bloch equations
Samyak Pratyush Prasad, Maria Maffei, Patrice A. Camati +2
Optical Bloch Equations (OBEs) are canonical equations describing the dynamics of a classically driven atom coupled to a thermal bath. Their thermodynamics is highly relevant to es…
