Compressed quantum metrology for the Ising Hamiltonian
W. L. Boyajian, M. Skotiniotis, W. Dür +1
We show how quantum metrology protocols that seek to estimate the parameters of a Hamiltonian that exhibits a quantum phase transition can be efficiently simulated on an exponentia…

Compressed simulation of thermal and excited states of the 1-D XY-model
Walter León Boyajian, Barbara Kraus
Since several years the preparation and manipulation of a small number of quantum systems in a controlled and coherent way is feasible in many experiments. In fact, these experimen…

Compressed Simulation of evolutions of the XY-model
Walter L. Boyajian, Valentin Murg, Barbara Kraus
We extend the notion of compressed quantum simulation to the XY-model. We derive a quantum circuit processing log(n) qubits which simulates the 1D XY-model describing n qubits. In…
