Quantum 8, 1491 (2024). https://doi.org/10.22331/q-2024-10-04-1491 ZX-calculus has proved to be a useful tool for quantum technology with a wide range of successful applications. Most of these applications are of an algebraic nature. However, other tasks […]
Quantum 8, 1490 (2024). https://doi.org/10.22331/q-2024-10-03-1490 The Born rule describes the probability of obtaining an outcome when measuring an observable of a quantum system. As it can only be tested by measuring many copies of the […]
Quantum 8, 1489 (2024). https://doi.org/10.22331/q-2024-10-02-1489 Investigations of the boundary of the quantum correlation set have gained increased attention in recent years. This is done through the derivation of quantum Bell inequalities, which are related to […]
Quantum 8, 1488 (2024). https://doi.org/10.22331/q-2024-10-02-1488 We establish the concept of topological pumping in one-dimensional systems with long-range couplings and apply it to the transport of a photon in quantum optical systems. In our theoretical investigation, […]
Quantum 8, 1487 (2024). https://doi.org/10.22331/q-2024-10-02-1487 Quantum phase estimation is one of the most powerful quantum primitives. This work proposes a new approach for the problem of multiple eigenvalue estimation: Quantum Multiple Eigenvalue Gaussian filtered Search […]
Humans are increasingly engaging with wearable technology as it becomes more adaptable and interactive. One of the most intimate ways gaining acceptance is through augmented reality glasses. Last week, Meta debuted a prototype of the […]
Quantum 8, 1486 (2024). https://doi.org/10.22331/q-2024-09-26-1486 Microscopic thermal machines promise to play an important role in future quantum technologies. Making such devices widely applicable will require effective strategies to channel their output into easily accessible storage […]
Quantum 8, 1485 (2024). https://doi.org/10.22331/q-2024-09-26-1485 Nonclassical causal modeling was developed in order to explain violations of Bell inequalities while adhering to relativistic causal structure and $faithfulness$—that is, avoiding fine-tuned causal explanations. Recently, a no-go theorem […]
Quantum 8, 1484 (2024). https://doi.org/10.22331/q-2024-09-25-1484 The training of a parameterized model largely depends on the landscape of the underlying loss function. In particular, vanishing gradients are a central bottleneck in the scalability of variational quantum […]
Quantum 8, 1483 (2024). https://doi.org/10.22331/q-2024-09-25-1483 Understanding the ultimate rate at which information propagates is a pivotal issue in nonequilibrium physics. Nevertheless, the task of elucidating the propagation speed inherent in quantum bosonic systems presents challenges […]
