When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, hides one of the oldest puzzles in physics: what really happens to the momentum of […]
Quantum 9, 1863 (2025). https://doi.org/10.22331/q-2025-09-24-1863 Memory or time-non-local effects in open quantum dynamics pose theoretical as well as practical challenges in the understanding and control of noisy quantum systems. While there has been a comprehensive […]
Quantum 9, 1862 (2025). https://doi.org/10.22331/q-2025-09-24-1862 We introduce an explicit construction for a key distribution protocol in the Quantum Computational Timelock (QCT) security model, where one assumes that computationally secure encryption may only be broken after […]
Insider Brief Researchers from Lawrence Livermore National Laboratory and University of California campuses have demonstrated the first miniaturized quadrupole ion traps created with ultrahigh-resolution 3D printing, a potential step toward scalable quantum computing. The printed […]
IonQ (NYSE: IONQ), with research support from the Air Force Research Lab (AFRL), has successfully demonstrated the frequency conversion of photons from visible to telecom wavelengths on a prototype system. This advancement is a step […]

Insider Brief Venture capitalist Alexa von Tobel is betting on quantum computing through her firm Inspired Capital, despite acknowledging the technology may take decades to mature and carries a high risk of failure. Inspired Capital, […]
In a study published in Reports on Progress in Physics, researchers have achieved device-independent characterization of genuinely entangled subspaces (GESs) in both optical and superconducting quantum systems, completing the self-checking of the five-qubit error correction […]
Dear Quantiki users, During the next few days (or weeks) our system will be upgraded. This might result in some unexpected behaviour and temporary site unavailability. Contact us if you need some help. We are […]
The quantum many body problem has been at the heart of much of theoretical and experimental physics over the past few decades. Even though we have understood the fundamental laws that govern the behavior of […]
