China’s Micius Military Quantum Satellite Reports Important Progress
Quantum encryption uses the principle of “quantum entanglement” to foster communication that’s totally safe against eavesdropping and decryption by others.
The satellite’s true military nature is being disguised under the civilian name, Quantum Experiments at Space Scale, or QUESS. Publicly, QUESS is being billed as an international research project in the field of quantum physics.
Micius or Mozi is operated by the Chinese Academy of Sciences (CAS) while the University of Vienna and the Austrian Academy of Sciences run the satellite’s European receiving stations. The quantum satellite was launched last Aug. 16 from the Jiuquan Satellite Launch Center in the Gobi Desert.
Breakthrough Quantum Cat Experiment Captured on Camera
The paradox of Schrödinger’s cat—in which a quantum cat is both alive and dead at the same time until we check to see which state it’s in—is arguably the most famous example of the bizarre counter-intuitive nature of the quantum world. Now, Stanford physicists have exploited this feature weirdness to make highly detailed movies of the inner machinery of simple iodine molecules.
Quantum computers will cripple encryption methods within decade, CSE head warns
Definitely less than a decade and even less than 7 especially with China Quantum Satellite, Google’s plan release next year of a Quantum device, etc. I hope folks don’t still believe that we’re immune from a QC attack after 2025.
In a rare public speech, Greta Bossenmaier, chief of the Communications Security Establishment, said cryptologists at the CSE and around the world are racing to find new cryptographic standards before Y2Q — years to quantum — predicted for 2026.
She is the third senior CSE official this week to warn publicly of the threat quantum computing poses to widely used public key cryptography (PKC), protecting sensitive data transmissions from hackers, hacktivists, foreign state spies and other malicious actors.

Diamond microdisk “with huge potential” for quantum computing
The diamond microdisk made by Paul Barclay and his team of physicists could lead to huge advances in computing, telecommunications, and other fields.
Barclay and his research group — part of the University of Calgary’s Institute for Quantum Science and Technology and the National Institute of Nanotechnology — have made the first-ever nano-sized optical resonator (or optical cavity) from a single crystal of diamond that is also a mechanical resonator.
The team also measured — in the coupling of light and mechanical motion in the device — the high-frequency, long-lasting mechanical vibrations caused by the energy of light trapped and bouncing inside the diamond microdisk optical cavity.
Calgary researchers teleport light particle 6.2 kilometres, raising hopes for ‘quantum internet’
The team’s article in Nature Photonics says the demonstration ‘constitutes a milestone towards a global quantum internet,’ as it is one of the longest distances over which quantum teleportation has been achieved using a fibre-optic network in this way.
In a “major step” toward practical quantum networking, researchers at the University of Calgary have successfully demonstrated the teleportation of a light particle’s properties between their lab and the city’s downtown area, six kilometres away.
“What is remarkable about this is that this information transfer happens in what we call a disembodied manner,” said physics professor Wolfgang Tittel, whose team’s work was published this week in the journal Nature Photonics.
“Our transfer happens without any need for an object to move between these two particles.”
How quantum computing could unpick encryption to reveal decades of online secrets
QC will need to be on any IT, Security, and/ or tech connected product future state roadmap that spans a 5 + year period because the planning, funding, change management (retooling of resources), etc. will take time to plan & prepare not to mention all those internal & external dependencies and their own efforts around QC in the future because it truly would stink to see an AT&T, or HomeDepot, etc. that invested in their own QC compliant infrastructure suddenly attacked because an external source that they pull from is not QC.
The encryption we take for granted as being uncrackable would have a limited shelf-life in the quantum age, says a security expert.
