Entanglement-assisted Hamiltonian dynamics learning

Ayaka Usui, Guillermo Abad-López, Hari krishnan SV +2

Approximating the dynamics given by a complex many-body Hamiltonian with a simpler effective model lies at the interface of quantum Hamiltonian learning and quantum simulation. In…

Emergent Bell Phase in an Electro-Nanomechanical Quantum Simulator

David Ullrich, Marta Cagetti, Stefan Forstner +2

Suspended carbon nanotubes hosting electrostatically defined quantum dots allow for exceptionally strong and tunable electromechanical coupling as well as mechanical modes that can…

Women for Quantum -- Manifesto of Values

Almut Beige, Ana Predojević, Anja Metelmann +30

Data show that the presence of women in quantum science is affected by a number of detriments and their percentage decreases even further for higher positions. Beyond data, from ou…

Simplifying the simulation of local Hamiltonian dynamics

Ayaka Usui, Anna Sanpera, María García Díaz

Local Hamiltonians, , describe non-trivial -body interactions in quantum many-body systems. Here, we address the dynamical simulatability of a -local Hamiltonian by a si…

Quantum privacy amplification and the security of quantum cryptography over noisy channels

D. Deutsch, A. Ekert, R. Jozsa +3

Existing quantum cryptographic schemes are not, as they stand, operable in the presence of noise on the quantum communication channel. Although they become operable if they are sup…
