Counterdiabatic driving in spin squeezing and Dicke state preparation
Tomáš Opatrný, Hamed Saberi, Etienne Brion +1
A method is presented to transfer a system of two-level atoms from a spin coherent state to a maximally spin squeezed Dicke state, relevant for quantum metrology and quantum inform…
Entanglement classification with matrix product states
M. Sanz, I. L. Egusquiza, R. Di Candia +3
Entanglement is widely considered the cornerstone of quantum information and an essential resource for relevant quantum effects, such as quantum teleportation, quantum cryptography…
Adiabatic tracking of quantum many-body dynamics
Hamed Saberi, Tomáš Opatrný, Klaus Mølmer +1
The nonadiabatic dynamics of a many-body system driven through a quantum critical point can be controlled using counterdiabatic driving, where the formation of excitations is suppr…
Uncontrolled disorder effects in fabricating photonic quantum simulators on a kagome geometry: A projected-entangled pair state versus exact digonalization analysis
Amin Hosseinkhani, Bahareh Ghannad Dezfouli, Fatemeh Ghasemipour +2
We propose a flexible numerical framework for extracting the energy spectra and photon transfer dynamics of a unit kagome cell with disordered cavity-cavity couplings under realist…
Genuine fidelity gaps associated with a sequential decomposition of genuinely entangling isometry and unitary operations
Hamed Saberi
We draw attention to the existence of "genuine" fidelity gaps in an ancilla-assisted sequential decomposition of genuinely entangling isometry and unitary operations of quantum com…
Efficient classical simulation of the Gisin-Massar quantum cloning machine
Hamed Saberi, Yousof Mardoukhi
We provide here the technical details of the recently proposed tensor-network protocol for classical simulation of the Gisin-Massar quantum cloner by the authors [Phys. Rev. A, 85,…
Sequential quantum cloning under real-life conditions
Hamed Saberi, Yousof Mardoukhi
We consider a sequential implementation of the optimal quantum cloning machine of Gisin and Massar and propose optimization protocols for experimental realization of such a quantum…
Ancilla-assisted sequential approximation of nonlocal unitary operations
Hamed Saberi
We consider the recently proposed "no-go" theorem of Lamata et al [Phys. Rev. Lett. 101, 180506 (2008)] on the impossibility of sequential implementation of global unitary operatio…
Constrained optimization of sequentially generated entangled multiqubit states
Hamed Saberi, Andreas Weichselbaum, Lucas Lamata +3
We demonstrate how the matrix-product state formalism provides a flexible structure to solve the constrained optimization problem associated with the sequential generation of entan…
