Simulating long-distance entanglement in quantum spin chains by superconducting flux qubits
Stefano Zippilli, Miroslav Grajcar, Evgeni Il'ichev +1
We investigate the performance of superconducting flux qubits for the adiabatic quantum simulation of long distance entanglement (LDE), namely a finite ground-state entanglement be…
Perturbative gadgets without strong interactions
Yudong Cao, Daniel Nagaj
Perturbative gadgets are used to construct a quantum Hamiltonian whose low-energy subspace approximates a given quantum -body Hamiltonian up to an absolute error . Typically,…
Optimal single shot strategies for discrimination of quantum measurements
Michal Sedlak, Mario Ziman
We study discrimination of m quantum measurements in the scenario when the unknown measurement with n outcomes can be used only once. We show that ancilla-assisted discrimination p…
Two Notes on Grover's Search: Programming and Discriminating
Daniel Reitzner, Mario Ziman
In this work we address two questions concerning Grover's algorithm. In the first we give an answer to the question how to employ Grover's algorithm for actual search over database…
Entanglement sensitivity to signal attenuation and amplification
Sergey N. Filippov, Mario Ziman
We analyze general laws of continuous-variable entanglement dynamics during the deterministic attenuation and amplification of the physical signal carrying the entanglement. These…
An adaptive attack on Wiesner's quantum money
Aharon Brodutch, Daniel Nagaj, Or Sattath +1
Unlike classical money, which is hard to forge for practical reasons (e.g. producing paper with a certain property), quantum money is attractive because its security might be based…
