Observations of the cosmos suggest that unseen sources of gravity — dark matter — tug at the stars in galaxies, while another mysterious force — dark energy — drives the universe to expand at an […]
Quantum 8, 1457 (2024). https://doi.org/10.22331/q-2024-08-29-1457 This work provides a nonasymptotic error analysis of quantum Krylov algorithms based on real-time evolutions, subject to generic errors in the outputs of the quantum circuits. We prove upper and […]
Quantum 8, 1456 (2024). https://doi.org/10.22331/q-2024-08-29-1456 Quantum state designs, by enabling an efficient sampling of random quantum states, play a quintessential role in devising and benchmarking various quantum protocols with broad applications ranging from circuit designs […]
Quantum 8, 1455 (2024). https://doi.org/10.22331/q-2024-08-29-1455 Classical shadows (CS) offer a resource-efficient means to estimate quantum observables, circumventing the need for exhaustive state tomography. Here, we clarify and explore the connection between CS techniques and least […]
Quantum 8, 1454 (2024). https://doi.org/10.22331/q-2024-08-29-1454 Most quantum theorists are familiar with different ways of describing the effective quantum dynamics of a system coupled to external degrees of freedom, such as the Born-Markov master equation or […]
