How far are quantum computers from practical applications? And what challenges must be overcome for them to reach their full potential? Nobel laureate John M. Martinis discusses these topics in an interview during his visit to this year’s PGI Day at Forschungszentrum Jülich From the interview:“[…] It’s important to be ready for all that. The… Read more »

Pre-print paper whose results might affect lattice-based PQC From the paper:“We present a polynomial-time quantum algorithm for the Dihedral Coset Problem (DCP). The algorithm is based on Regev’s polynomial-time reduction of the Dihedral Subgroup Problem (DSP) to the modular subset sum problem, but uses a different technique to erase sample bits without use of a… Read more »

A report by Brian Couzens (SITG Consulting) From the guidelines:“This report assesses publicly verifiable national preparation for the migration to post-quantum cryptography (PQC) across all 27 Member States of the European Union, as at 3 August 2026. The assessment was conducted because the discussion of post-quantum readiness has become dominated by declarations of intent. Standards… Read more »

From the post:“The Bundesbank is collaborating with satellite operator SES to explore potential applications of quantum key distribution via satellite. Both partners have agreed to this in a memorandum of understanding. […] ‘This partnership is a key step toward protecting our data communications in the long term—for example, against attacks by future quantum computers’, emphasizes… Read more »
