The geometry of absolute separability and other convex matrix properties from spectrum
Jennifer Ahiable, Naga Bhavya Teja Kothakonda, Andreas Winter
We investigate the geometric structure of the set of spectra of bipartite absolute separable states () and absolute positive partial transpose states ($\mathrm…
Threshold entanglement sharing: quantum states with absolutely separable marginals
Albert Rico, Jofre Abellanet-Vidal, Naga Bhavya Teja Kothakonda +2
Motivated to understand how entanglement resources can be distributed in quantum networks, we introduce threshold entanglement (TE) states. These are multipartite quantum states wh…
Cloning Quantum Channels
Pavel Sekatski, Yelena Guryanova, Naga Bhavya Teja Kothakonda +1
We consider the problem of deterministically cloning quantum channels with respect to the best attainable rate and the highest quality, so-called optimal cloning. We demonstrate th…
Complexity-constrained quantum thermodynamics
Anthony Munson, Naga Bhavya Teja Kothakonda, Jonas Haferkamp +3
Quantum complexity measures the difficulty of realizing a quantum process, such as preparing a state or implementing a unitary. We present an approach to quantifying the thermodyna…
