Comment on "How to observe and quantify quantum-discord states via correlations"
Parveen Kumar, Kyrylo Snizhko
The protocol proposed in the commented-upon article can certify zero discord; however, it fails to quantify non-zero discord for some states. Further, the protocol is less efficien…
Quantum Zeno effect with partial measurement and noisy dynamics
Parveen Kumar, Alessandro Romito, Kyrylo Snizhko
We study the Quantum Zeno Effect (QZE) induced by continuous partial measurement in the presence of short-correlated noise in the system Hamiltonian. We study the survival probabil…
Engineering two-qubit mixed states with weak measurements
Parveen Kumar, Kyrylo Snizhko, Yuval Gefen
It is known that protocols based on weak measurements can be used to steer quantum systems into pre-designated pure states. Here we show that weak-measurement-based steering protoc…
Quantum Zeno effect appears in stages
Kyrylo Snizhko, Parveen Kumar, Alessandro Romito
In the quantum Zeno effect, quantum measurements can block the coherent oscillation of a two level system by freezing its state to one of the measurement eigenstates. The effect is…
Topological transition in measurement-induced geometric phases
Valentin Gebhart, Kyrylo Snizhko, Thomas Wellens +3
The state of a quantum system, adiabatically driven in a cycle, may acquire a measurable phase depending only on the closed trajectory in parameter space. Such geometric phases are…
Bounds on nonlocal correlations in the presence of signaling and their application to topological zero modes
Avishy Carmi, Yaroslav Herasymenko, Eliahu Cohen +1
Bell's theorem renders quantum correlations distinct from those of any local-realistic model. Although being stronger than classical correlations, quantum correlations are limited…
