Quantum 6, 628 (2022). https://doi.org/10.22331/q-2022-01-24-628 We explore a method for automatically recompiling a quantum circuit $mathcal{A}$ into a target circuit $mathcal{B}$, with the goal that both circuits have the same action on a specific input […]
Quantum 6, 627 (2022). https://doi.org/10.22331/q-2022-01-20-627 A promising application of neural-network quantum states is to describe the time dynamics of many-body quantum systems. To realize this idea, we employ neural-network quantum states to approximate the implicit […]
Quantum 6, 626 (2022). https://doi.org/10.22331/q-2022-01-20-626 The characterization of mixtures of non-interacting, spectroscopically similar quantum components has important applications in chemistry, biology, and materials science. We introduce an approach based on quantum tracking control that allows […]
Quantum 6, 625 (2022). https://doi.org/10.22331/q-2022-01-20-625 We give a quantum speedup for solving the canonical semidefinite programming relaxation for binary quadratic optimization. This class of relaxations for combinatorial optimization has so far eluded quantum speedups. Our […]
This year Quantum will celebrate 5 years since the first publications! From that first batch of papers, the journal grew to over 600 published articles. This growth was made possible by our incredible team of editors, […]
Quantum 6, 624 (2022). https://doi.org/10.22331/q-2022-01-18-624 Quenching and annealing are extreme opposites in the time evolution of a quantum system: Annealing explores equilibrium phases of a Hamiltonian with slowly changing parameters and can be exploited as […]
Quantum 6, 623 (2022). https://doi.org/10.22331/q-2022-01-18-623 We investigate temporal correlations in the simplest measurement scenario, i.e., that of a physical system on which the same measurement is performed at different times, producing a sequence of dichotomic […]
Quantum 6, 622 (2022). https://doi.org/10.22331/q-2022-01-18-622 In recent years simulations of chemistry and condensed materials has emerged as one of the preeminent applications of quantum computing, offering an exponential speedup for the solution of the electronic […]
Quantum 6, 621 (2022). https://doi.org/10.22331/q-2022-01-11-621 The study of causal relations has recently been applied to the quantum realm, leading to the discovery that not all physical processes have a definite causal structure. While indefinite causal […]
Quantum 6, 620 (2022). https://doi.org/10.22331/q-2022-01-05-620 We introduce new methods and tools to study and characterise classical and quantum correlations emerging from prepare-and-measure experiments with informationally restricted communication. We consider the most general kind of informationally […]
