A universal fault-tolerant quantum computer that can efficiently solve problems such as
integer factorization and unstructured database search requires millions of qubits with low …

We present Qibo, a new open-source software for fast evaluation of quantum circuits and
adiabatic evolution which takes full advantage of hardware accelerators. The growing …

We present a variational quantum circuit that produces the singular value decomposition of
a bipartite pure state. The proposed circuit, which we name quantum singular value …

We study quantum circuits composed of a sequence of CNOT gates between distant qubits
of an-qubit system. We present some results concerning two important topics related to …

Quantum computing is currently hindered by hardware noise. We present a freestyle
superconducting pulse optimization method, incorporating two-qubit channels, that …

The absolute values of polynomial SLOCC invariants (which always vanish on separable
states) can be seen as entanglement measures. We study the case of real 3-qutrit systems …

Among the various quantum phenomena that contribute to the efficiency of quantum
computation compared to classical computation, entanglement plays a pivotal role. To …

We study entanglement and nonlocality of connected four-qubit hypergraph states. One
obtains the Stochastic Local Operations and Classical Communication (SLOCC) …

Characterizing large noisy multiparty quantum states using genuine multipartite
entanglement is a challenging task. In this paper, we calculate lower bounds of genuine …

In this work, we explore how resources are distributed among the states generated by
quantum random circuits (QRC). We focus on multipartite non-locality, but we also analyze …
