Quantum Zeitgeist

Singapore & Luxembourg will deepen cooperation in areas like artificial intelligence, and quantum technology, plus space tech.

An SMU professor, Paul Griffin, warns Singapore must proactively develop quantum tech skills now, as quantum computers pose a cryptographic threat AI can’t address.

Fujitsu today announced the development of the world’s first working prototype of a diamond-spin quantum computer incorporating tin-vacancy (SnV) centers into photonic integrated circuits. The prototype, which can be operated at -271.6°C, has been demonstrated in a test environment via the Fujitsu Hybrid Quantum Computing Platform.

NVIDIA explores how to build security into AI agents, citing recent reports of “frontier agents” exceeding boundaries—like those from OpenAI and Anthropic.

SEMIFIVE announced today the mass production of a data center AI inference accelerator for HyperAccel, marking its first large-scale project utilizing Samsung Foundry’s 4nm process node. Following an initial production contract, mass production volumes are projected to expand with follow-on purchase orders aligned with HyperAccel’s rollout.

Researchers from the University of Surrey have introduced a conceptual design for a new type of qubit, using superfluid helium-3, that could be much less vulnerable to errors. The team’s calculations predict error rates around 100 times lower than conventional superconducting qubits.

The development offers a potential route to more affordable three-dimensional imaging; current optical coherence tomography systems often rely on expensive single-photon detectors to capture faint light signals. However, the researchers explicitly state their findings are limited “under the conditions considered”, raising concerns about how well this seeded approach will perform when faced with r…

Can image restoration algorithms truly benefit from techniques borrowed from quantum physics without sacrificing performance stability? TT-Net demonstrates they can, exceeding the denoising capabilities of existing methods like SVD-Net, EigenGAN and Pix2pix on images corrupted by Gaussian blur, motion artefacts or salt-and-pepper noise. This improvement stems from a novel decomposition that allow…

Explore quantum computing at Moth Hack 2026 in London, with free, walk-in access to try the Moth’s Atlas platform and engage with the team, Saturday & Sunday.

QOLLAB and IONQ host a global build weekend this October, SESSION 2026.10.09—registration is currently closed for this quantum computing event.

Two-qubit controlled gates, such as the controlled-Y gate, are essential building blocks for universal quantum computation. Researchers propose and numerically demonstrate an optical quantum controlled-Y gate based on a single-layer Pancharatnam–Berry gradient metasurface operating at 1550 nm.

Previously, maintaining stable quantum information within silicon required shielding qubits or pausing computation to avoid disruptive noise. Now, a new protocol decouples this noise not only when idle but also *during* active processing, safeguarding against both signal degradation and driving errors. Extending established continuous driving techniques to these challenging ‘hole’ spins opens ave…

A new model-based framework automatically quantifies sources of degradation in generated quantum states, crucial for applications like quantum computing.

Researchers boosted the accuracy of simulating nuclear motion with a new method for fault-tolerant quantum computers, utilizing a Walsh–Hadamard transform and discrete variable representation for high-fidelity results.

Lanthanide-based upconversion nanoparticles, or UCNPs, act as frequency mixers, generating beat frequencies from modulated excitation.

Can complex systems exhibiting glass-like behaviour be probed one trajectory at a time using today’s quantum computers? Measurements on a superconducting processor now demonstrate that detailed observation *is* possible, revealing how inactivity spreads through the system via analysis of space-time regions. This establishes present day processors as platforms capable of studying these dynamics be…

The INFN and CERN have begun the fifth Art&Science masterclass, welcoming 30 Italian students—winners of a national competition—to Geneva for a week of physics, art, and workshops.

Tuomo Hartonen joins FIMM-EMBL as a Group Leader, focusing AI research on population health and large-scale data.

Detector choice isn’t simple—consider tradeoffs between detection efficiency, timing jitter, and operating wavelength.
