Criticality of environmental information obtainable by dynamically controlled quantum probes
Analia Zwick, Gonzalo A. Alvarez, Gershon Kurizki
A universal approach to decoherence control combined with quantum estimation theory reveals a critical behavior, akin to a phase transition, of the information obtainable by a qubi…
Thermal Baths as Quantum Resources: More Friends than Foes?
Gershon Kurizki, Ephraim Shahmoon, Analia Zwick
In this article we argue that thermal reservoirs (baths) are potentially useful resources in processes involving atoms interacting with quantized electromagnetic fields and their a…
Maximizing information on the environment by dynamically controlled qubit probes
Analia Zwick, Gonzalo A. Alvarez, Gershon Kurizki
We explore the ability of a qubit probe to characterize unknown parameters of its environment. By resorting to quantum estimation theory, we analytically find the ultimate bound on…
Robustness of spin-chain state-transfer schemes
Joachim Stolze, Gonzalo A. Alvarez, Omar Osenda +1
This is a shortened and slightly edited version of a chapter in the collection "Quantum State Transfer and Network Engineering", edited by G.M. Nikolopoulos and I. Jex, where we re…
Optimized dynamical control of state transfer through noisy spin chains
Analia Zwick, Gonzalo A. Alvarez, Guy Bensky +1
We propose a method of optimally controlling the tradeoff of speed and fidelity of state transfer through a noisy quantum channel (spin-chain). This process is treated as qubit sta…
