Quantum 10, 1983 (2026). https://doi.org/10.22331/q-2026-01-22-1983 We study the properties of photons in a cryogenic cavity, made by cryo-cooled mirrors surrounded by a room temperature environment. We model such a system as a multimode cavity coupled […]
Quantum 10, 1982 (2026). https://doi.org/10.22331/q-2026-01-22-1982 Interplay between quantum interference and classical randomness can enhance performance of various quantum information tasks. In the present paper we analyze recurrence phenomena in the discrete-time quantum stochastic walk on […]
Quantum 10, 1981 (2026). https://doi.org/10.22331/q-2026-01-22-1981 Sampling from Gibbs states – states corresponding to system in thermal equilibrium – has recently been shown to be a task for which quantum computers are expected to achieve super-polynomial […]
Quantum 10, 1980 (2026). https://doi.org/10.22331/q-2026-01-22-1980 Signing quantum messages has long been considered impossible even under computational assumptions. In this work, we challenge this notion and provide three innovative approaches to sign quantum messages that are […]
Scientists are learning how to temporarily reshape materials by nudging their internal quantum rhythms instead of blasting them with extreme lasers. By harnessing excitons, short-lived energy pairs that naturally form inside semiconductors, researchers can alter […]
When quantum spins interact, they can produce collective behaviors that defy long-standing expectations. Researchers have now shown that the Kondo effect behaves very differently depending on spin size. In systems with small spins, it suppresses […]
Photonics for Quantum (P4Q), a major European pilot line, has been launched with a €50 million ($58.4 million USD) budget to transition quantum photonic technologies from laboratory research to industrial manufacturing. Coordinated by the University […]
King Abdullah University of Science and Technology (KAUST) has launched the KAUST Quantum Foundry, a specialized program dedicated to the fabrication of reproducible and commercial-grade quantum hardware. Located in Saudi Arabia, the Foundry provides structured […]
Research in the lab of UC Santa Barbara materials professor Stephen Wilson is focused on understanding the fundamental physics behind unusual states of matter and developing materials that can host the kinds of properties needed […]
For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years’ time, they could change the […]
