Experimental Quantum Fast Hitting on Hexagonal Graphs
Hao Tang, Carlo Di Franco, Zi-Yu Shi +9
Quantum walks are powerful kernels in quantum computing protocols that possess strong capabilities in speeding up various simulation and optimisation tasks. One striking example is…
Bypassing state initialization in Hamiltonian tomography on spin-chains
C. Di Franco, M. Paternostro, M. S. Kim
We provide an extensive discussion on a scheme for Hamiltonian tomography of a spin-chain model that does not require state initialization [Phys. Rev. Lett. 102, 187203 (2009)]. Th…
Mimicking the probability distribution of a two-dimensional Grover walk with a single-qubit coin
C. Di Franco, M. McGettrick, Th. Busch
Multi-dimensional quantum walks usually require large coin spaces. Here we show that the non-localized case of the spatial density probability of the two-dimensional Grover walk ca…
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…
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…
