Berry Phase Estimation in Gate-Based Adiabatic Quantum Simulation
Bruno Murta, G. Catarina, J. Fernandez-Rossier
Gate-based quantum computers can in principle simulate the adiabatic dynamics of a large class of Hamiltonians. Here we consider the cyclic adiabatic evolution of a parameter in th…
Optimizing quantum phase estimation for the simulation of Hamiltonian eigenstates
P. M. Q. Cruz, G. Catarina, R. Gautier +1
We revisit quantum phase estimation algorithms for the purpose of obtaining the energy levels of many-body Hamiltonians and pay particular attention to the statistical analysis of…
Experimental quantification of genuine four-photon indistinguishability
Taira Giordani, Daniel J. Brod, Chiara Esposito +7
Photon indistinguishability plays a fundamental role in information processing, with applications such as linear-optical quantum computation and metrology. It is then necessary to…
Continuous-variable nonlocality and contextuality
Rui Soares Barbosa, Tom Douce, Pierre-Emmanuel Emeriau +2
Contextuality is a non-classical behaviour that can be exhibited by quantum systems. It is increasingly studied for its relationship to quantum-over-classical advantages in informa…
Quantum and classical bounds for two-state overlaps
Ernesto F. Galvão, Daniel J. Brod
Suppose we have quantum systems in unknown states , but know the value of some pairwise overlaps . What can…
