Quantum Kibble-Zurek physics in long-range transverse-field Ising models
Ricardo Puebla, Oliver Marty, Martin B. Plenio
We analyze the quantum phase transitions taking place in a one-dimensional transverse field Ising model with long-range couplings that decay algebraically with distance. We are int…
Dissipation-assisted matrix product factorization
Alejandro D. Somoza, Oliver Marty, James Lim +2
Charge and energy transfer in biological and synthetic organic materials are strongly influenced by the coupling of electronic states to high-frequency underdamped vibrations under…
Observation of Entangled States of a Fully Controlled 20-Qubit System
Nicolai Friis, Oliver Marty, Christine Maier +8
We generate and characterise entangled states of a register of 20 individually controlled qubits, where each qubit is encoded into the electronic state of a trapped atomic ion. Ent…
Multiparticle entanglement criteria for nonsymmetric collective variances
Oliver Marty, Marcus Cramer, Giuseppe Vitagliano +2
We introduce a general scheme to detect various multiparticle entanglement structures from global non-permutationally invariant observables. In particular, we derive bounds on the…
Practical Entanglement Estimation for Spin-System Quantum Simulators
O. Marty, M. Cramer, M. B. Plenio
We present practical methods to measure entanglement for quantum simulators that can be realized with trapped ions, cold atoms, and superconducting qubits. Focussing on long- and s…
Quantifying entanglement with scattering experiments
O. Marty, M. Epping, H. Kampermann +3
We show how the entanglement contained in states of spins arranged on a lattice may be quantified with observables arising in scattering experiments. We focus on the partial differ…
