The future of computing lies in the surprising world of quantum physics, where the rules are much different from the ones that power today’s devices. Quantum computers promise to tackle problems too complex for even […]
Quantum 9, 1871 (2025). https://doi.org/10.22331/q-2025-10-01-1871 We extend the concept of operator charge in the context of an abelian $U(1)$ symmetry and apply this framework to symmetry-preserving matrix product operators (MPOs), enabling the description of operators […]
Quantum 9, 1870 (2025). https://doi.org/10.22331/q-2025-10-01-1870 Genuine multipartite entanglement of a given multipartite pure quantum state can be quantified through its geometric measure of entanglement, which, up to logarithms, is simply the maximum overlap of the […]
If there’s one law of physics that seems easy to grasp, it’s the second law of thermodynamics: Heat flows spontaneously from hotter bodies to colder ones. But now, gently and almost casually, Alexssandre de Oliveira […]

Qilimanjaro Quantum Tech, a Barcelona-based quantum computing company, has announced that it is now an integration partner of IMPAQT UA, a Delft-based cooperative consortium of quantum technology companies. This partnership strengthens European collaboration in building […]
Optical clocks are highly precise timekeeping devices that measure time by tracking the oscillations of light, as opposed to microwaves, like conventional atomic clocks. The accuracy of these clocks heavily depends on the ability to […]
Quantum Brilliance, CyberSeQ, and LuxProvide have announced a letter of intent to collaborate on quantum-secure encryption methods aligned with Post-Quantum Cryptography (PQC). The partnership will focus on algorithms that use certified true random numbers to […]
Quantum 9, 1869 (2025). https://doi.org/10.22331/q-2025-10-01-1869 Twin-Field Quantum Key Distribution (QKD) is a QKD protocol that uses single-photon interference to perform QKD over long distances. QKD protocols that encode information using high-dimensional quantum states can benefit […]
