Lossy Micromaser Battery: Almost Pure States in the Jaynes-Cummings Regime
Vahid Shaghaghi, Varinder Singh, Matteo Carrega +2
We consider a micromaser model of a quantum battery, where the battery is a single mode of the electromagnetic field in a cavity, charged via repeated interactions with a stream of…
Distributions of the Wigner reaction matrix for microwave networks with symplectic symmetry in the presence of absorption
Michal Lawniczak, Afshin Akhshani, Omer Farooq +4
We report on experimental studies of the distribution of the reflection coefficients, and the imaginary and real parts of Wigner's reaction (K) matrix employing open microwave netw…
Entanglement dynamics and classical complexity
Jiaozi Wang, Barbara Dietz, Dario Rosa +1
We study the dynamical generation of entanglement for a two-body interacting system, starting from a separable coherent state. We show analytically that in the quasiclassical regim…
Recursive QAOA outperforms the original QAOA for the MAX-CUT problem on complete graphs
Eunok Bae, Soojoon Lee
Quantum approximate optimization algorithms are hybrid quantum-classical variational algorithms designed to approximately solve combinatorial optimization problems such as the MAX-…
Quantum advantage through the magic pentagram problem
Haesol Han, Jeonghyeon Shin, Minjin Choi +2
Through the two specific problems, the 2D hidden linear function problem and the 1D magic square problem, Bravyi et al. have recently shown that there exists a separation between $…
Work extraction from unknown quantum sources
Dominik Šafránek, Dario Rosa, Felix Binder
Energy extraction is a central task in thermodynamics. In quantum physics, ergotropy measures the amount of work extractable under cyclic Hamiltonian control. As its full extractio…
