Quantum 8, 1248 (2024). https://doi.org/10.22331/q-2024-02-12-1248 In the absence of a complete theory of quantum gravity, phenomenological models built upon minimal assumptions have been explored for the analysis of possible quantum effects in gravitational systems. Implications […]
Quantum 8, 1247 (2024). https://doi.org/10.22331/q-2024-02-12-1247 We present $texttt{Qibolab}$, an open-source software library for quantum hardware control integrated with the $texttt{Qibo}$ quantum computing middleware framework. $texttt{Qibolab}$ provides the software layer required to automatically execute circuit-based algorithms […]
Quantum 8, 1246 (2024). https://doi.org/10.22331/q-2024-02-12-1246 Quantum instruments describe outcome probability as well as state change induced by measurement of a quantum system. Incompatibility of two instruments, i. e. the impossibility to realize them simultaneously on […]
Quantum 8, 1245 (2024). https://doi.org/10.22331/q-2024-02-08-1245 We present a generalized framework to adapt universal quantum state approximators, enabling them to satisfy rigorous normalization and autoregressive properties. We also introduce filters as analogues to convolutional layers in […]
Quantum 8, 1244 (2024). https://doi.org/10.22331/q-2024-02-08-1244 We present an analytical method to estimate pure quantum states using a minimum of three measurement bases in any finite-dimensional Hilbert space. This is optimal as two bases are insufficient […]
Quantum 8, 1243 (2024). https://doi.org/10.22331/q-2024-02-06-1243 We provide new examples of pure entangled systems related to cluster state quantum computation that can be efficiently simulated classically. In cluster state quantum computation input qubits are initialised in […]
Quantum 8, 1242 (2024). https://doi.org/10.22331/q-2024-02-05-1242 Classical non-perturbative simulations of open quantum systems’ dynamics face several scalability problems, namely, exponential scaling of the computational effort as a function of either the time length of the simulation […]
Quantum 8, 1241 (2024). https://doi.org/10.22331/q-2024-02-05-1241 Quantum processes with indefinite causal structure emerge when we wonder which are the most general evolutions, allowed by quantum theory, of a set of local systems which are not assumed […]
Quantum 8, 1240 (2024). https://doi.org/10.22331/q-2024-02-05-1240 We analyse nonclassical resources in interference phenomena using generalized noncontextuality inequalities and basis-independent coherence witnesses. We use recently proposed inequalities that witness both resources within the same framework. We also […]
Quantum 8, 1239 (2024). https://doi.org/10.22331/q-2024-02-01-1239 Variational quantum algorithms, which combine highly expressive parameterized quantum circuits (PQCs) and optimization techniques in machine learning, are one of the most promising applications of a near-term quantum computer. Despite […]
