Generating "squeezed" superpositions of coherent states using photon addition and subtraction
P. Marek, H. Jeong, M. S. Kim
We study how photon addition and subtraction can be used to generate squeezed superpositions of coherent states in free-traveling fields (SSCSs) with high fidelities and large ampl…
Hamiltonian tomography in an access-limited setting without state initialization
C. Di Franco, M. Paternostro, M. S. Kim
We propose a scheme for the determination of the coupling parameters in a chain of interacting spins. This requires only time-resolved measurements over a single particle, simple d…
Positive phase space transformation incompatible with classical physics
Wonmin Son, Johannes Kofler, M. S. Kim +2
Bell conjectured that a positive Wigner function does not allow violation of the inequalities imposed by local hidden variable theories. A requirement for this conjecture is "when…
A deeper insight into quantum state transfer from an information flux viewpoint
C. Di Franco, M. Paternostro, G. M. Palma
We use the recently introduced concept of information flux in a many-body register in order to give an alternative viewpoint on quantum state transfer in linear chains of many spin…
Control-limited perfect state transfer, quantum stochastic resonance and many-body entangling gate in imperfect qubit registers
C. Di Franco, M. Paternostro, D. I. Tsomokos +1
We propose a protocol for perfect quantum state transfer that is resilient to a broad class of realistic experimental imperfections, including noise sources that could be modelled…
