Quantum 9, 1585 (2025). https://doi.org/10.22331/q-2025-01-08-1585 Optical lattices serve as fundamental building blocks for atomic quantum technology. However, the scale and resolution of these lattices are diffraction-limited to the light wavelength. In conventional lattices, achieving tight […]
Quantum 9, 1584 (2025). https://doi.org/10.22331/q-2025-01-08-1584 We present $texttt{Cryptomite}$, a Python library of randomness extractor implementations. The library offers a range of two-source, seeded and deterministic randomness extractors, together with parameter calculation modules, making it easy […]
Quantum 9, 1583 (2025). https://doi.org/10.22331/q-2025-01-08-1583 Linear constraint systems (LCS) have proven to be a surprisingly prolific tool in the study of non-classical correlations and various related issues in quantum foundations. Many results are known for […]
Quantum 9, 1582 (2025). https://doi.org/10.22331/q-2025-01-08-1582 Uncloneable encryption, first introduced by Broadbent and Lord (TQC 2020) is a quantum encryption scheme in which a quantum ciphertext cannot be distributed between two non-communicating parties such that, given […]
Quantum 9, 1581 (2025). https://doi.org/10.22331/q-2025-01-08-1581 A core challenge for superconducting quantum computers is to scale up the number of qubits in each processor without increasing noise or cross-talk. Distributed quantum computing across small qubit arrays, […]
Quantum 8, 1580 (2024). https://doi.org/10.22331/q-2024-12-27-1580 Tensor network contractions are widely used in statistical physics, quantum computing, and computer science. We introduce a method to efficiently approximate tensor network contractions using low-rank approximations, where each intermediate […]
Quantum 8, 1579 (2024). https://doi.org/10.22331/q-2024-12-27-1579 As a signal recovery algorithm, compressed sensing is particularly effective when the data has low complexity and samples are scarce, which aligns natually with the task of quantum phase estimation […]
Quantum 8, 1578 (2024). https://doi.org/10.22331/q-2024-12-27-1578 The rotation of trapped molecules offers a promising platform for quantum technologies and quantum information processing. In parallel, quantum error correction codes that can protect quantum information encoded in rotational […]
Quantum 8, 1577 (2024). https://doi.org/10.22331/q-2024-12-27-1577 As current experiments already realize small quantum circuits on error corrected qubits, it is important to fully understand the effect of physical errors on the logical error channels of these […]
Quantum 8, 1576 (2024). https://doi.org/10.22331/q-2024-12-23-1576 Understanding the influence of measurements on the properties of many-body systems is a fundamental problem in quantum mechanics and for quantum technologies. This paper explores how a finite density of […]
