Lower Bounding Ground-State Energies of Local Hamiltonians Through the Renormalization Group
Ilya Kull, Norbert Schuch, Ben Dive +1
Given a renormalization scheme, we show how to formulate a tractable convex relaxation of the set of feasible local density matrices of a many-body quantum system. The relaxation i…
Entanglement Detection Beyond Measuring Fidelities
Mirjam Weilenmann, Benjamin Dive, David Trillo +2
One of the most widespread methods to determine if a quantum state is entangled, or to quantify its entanglement dimensionality, is by measuring its fidelity with respect to a pure…
Translating Uncontrolled Systems in Time
David Trillo, Benjamin Dive, Miguel Navascues
We show that there exist non-relativistic scattering experiments which, if successful, freeze out, speed up or even reverse the free dynamics of any ensemble of quantum systems pre…
Characterisation of multi-level quantum coherence without ideal measurements
Benjamin Dive, Nikolaos Koukoulekidis, Stefanos Mousafeiris +1
Coherent superpositions are one of the hallmarks of quantum mechanics and are vital for any quantum mechanical device to outperform the classically achievable. Generically, superpo…
Accelerating adiabatic protocols for entangling two qubits in circuit QED
Francesco Petiziol, Benjamin Dive, Stefano Carretta +3
We introduce a method to speed up adiabatic protocols for creating entanglement between two qubits dispersively coupled to a transmission line, while keeping fidelities high and ma…
Fast adiabatic evolution by oscillating initial Hamiltonians
Francesco Petiziol, Benjamin Dive, Florian Mintert +1
We propose a method to produce fast transitionless dynamics for finite-dimensional quantum systems without requiring additional Hamiltonian components not included in the initial c…
