Quantized time in quantum walks under weak rank-K measurements
Klaus Ziegler
Measurements can be used to monitor the evolution of quantum systems and may lead to a universally quantized time statistics. It is known that the mean return time is quantized for…
Optical Transmission of 2D Material with Quantum Anomalous Hall Effect
Nathan Pravda, Oleg L. Berman, Klaus Ziegler
We study the optical properties of gapped two-dimensional materials which are subject to the quantum anomalous Hall effect. At sufficiently low temperatures the transmission, refle…
Monitoring photon entanglement in coupled cavities
Moises Acero, Jeremiah Harrington, Oleg L. Berman +1
We study the dynamics of photons in a Fock state, initially located inside one cavity, and coupled by an optical fiber to a second cavity. The entanglement of the photons is mo…
Monitoring of quantum walks with weak measurements
Klaus Ziegler, Tim Heine, Sabine Tornow
Measurements can be used to monitor the evolution of quantum systems and can give rise to quantized return statistics. It is known that the mean return time is quantized for strong…
Localized states in monitored quantum walks
Klaus Ziegler
In this paper we study localized states in a monitored evolution on a finite graph and how they are distinguished from the delocalized states in terms of the transition probabiliti…
Repeated measurements and random scattering in quantum walks
Klaus Ziegler
We study the effect of random scattering in quantum walks on a finite graph and compare it with the effect of repeated measurements. To this end, a constructive approach is employe…
An invariant measure of chiral quantum transport
Klaus Ziegler
We study the invariant measure of the transport correlator for a chiral Hamiltonian and analyze its properties. The Jacobian of the invariant measure is a function of random phases…
