Quantum 8, 1428 (2024). https://doi.org/10.22331/q-2024-07-30-1428 We analyze the efficiency of protocols for adiabatic quantum state transfer assisted by an engineered reservoir. The target dynamics is a quantum trajectory in the Hilbert space and is a […]
Quantum 8, 1427 (2024). https://doi.org/10.22331/q-2024-07-30-1427 Quantum systems of infinite dimension, such as bosonic oscillators, provide vast resources for quantum sensing. Yet, a general theory on how to manipulate such bosonic modes for sensing beyond parameter […]
Quantum 8, 1426 (2024). https://doi.org/10.22331/q-2024-07-30-1426 We present a general denoising algorithm for performing $textit{simultaneous tomography}$ of quantum states and measurement noise. This algorithm allows us to fully characterize state preparation and measurement (SPAM) errors present […]
Quantum 8, 1425 (2024). https://doi.org/10.22331/q-2024-07-25-1425 Tensor networks, widely used for providing efficient representations of low-energy states of local quantum many-body systems, have been recently proposed as machine learning architectures which could present advantages with respect […]
Quantum 8, 1424 (2024). https://doi.org/10.22331/q-2024-07-25-1424 The Trotter product formula and the quantum Zeno effect are both indispensable tools for constructing time-evolutions using experimentally feasible building blocks. In this work, we discuss assumptions under which quantitative […]
Quantum 8, 1423 (2024). https://doi.org/10.22331/q-2024-07-24-1423 We introduce an adaptable and modular hybrid architecture designed for fault-tolerant quantum computing. It combines quantum emitters and linear-optical entangling gates to leverage the strength of both matter-based and photonic-based […]
Quantum 8, 1422 (2024). https://doi.org/10.22331/q-2024-07-23-1422 We introduce a quantum information theory-inspired method to improve the characterization of many-body Hamiltonians on near-term quantum devices. We design a new class of similarity transformations that, when applied as […]
Quantum 8, 1421 (2024). https://doi.org/10.22331/q-2024-07-22-1421 Identifying phases of matter presents considerable challenges, particularly within the domain of quantum theory, where the complexity of ground states appears to increase exponentially with system size. Quantum many-body systems […]
Quantum 8, 1420 (2024). https://doi.org/10.22331/q-2024-07-22-1420 Several notions of code products are known in quantum error correction, such as hypergraph products, homological products, lifted products, balanced products, to name a few. In this paper we introduce […]
Quantum 8, 1419 (2024). https://doi.org/10.22331/q-2024-07-19-1419 Quantum networks with multiple sources allow the observation of quantum nonlocality without inputs. Consequently, the incompatibility of measurements is not a necessity for observing quantum nonlocality when one has access […]
