Quantum 9, 1586 (2025). https://doi.org/10.22331/q-2025-01-08-1586 The stabiliser formalism plays a central role in quantum computing, error correction, and fault tolerance. Conversions between and verifications of different specifications of stabiliser states and Clifford gates are important […]
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, […]
Amid the many mysteries of quantum physics, subatomic particles don’t always follow the rules of the physical world. They can exist in two places at once, pass through solid barriers and even communicate across vast […]
Insider Brief: Elmos Semiconductor and ID Quantique have partnered to develop the world’s smallest monolithic quantum random number generator chip. The QRNG chip uses quantum in-chip photoemission to produce high-quality randomness, and support cryptographic security […]
