Faster ground state preparation and high-precision ground energy estimation with fewer qubits
Yimin Ge, Jordi Tura, J. Ignacio Cirac
We propose a general-purpose quantum algorithm for preparing ground states of quantum Hamiltonians from a given trial state. The algorithm is based on techniques recently developed…

Bounding the set of classical correlations of a many-body system
Matteo Fadel, Jordi Tura
We present a method to certify the presence of Bell correlations in experimentally observed statistics, and to obtain new Bell inequalities. Our approach is based on relaxing the c…

Separability of diagonal symmetric states: a quadratic conic optimization problem
Jordi Tura, Albert Aloy, Ruben Quesada +2
We study the separability problem in mixtures of Dicke states i.e., the separability of the so-called Diagonal Symmetric (DS) states. First, we show that separability in the case o…
