Microsoft on Wednesday unveiled a new chip that it said showed quantum computing is "years, not decades" away, predicting that a fundamental change in computing technology is much closer than recently believed. https://www.japantimes.co.jp/business/2025/02/20/tech/microsoft-new-quantum-computer-chip/?utm_medium=Social&utm_source=mastodon #business #tech #microsoft #quantumcomputers #chipmakers
Tuta email, located in Germany, Europe, now uses quantum computers to encrypt their emails.
(Technically, they are using algorithms determined to be safe against attacks from quantum computers. And they don't actually have a quantum computer running 24/7, but that is good enough for me.)

Gearing up for the future of cryptography!

Slightly older post, but I just became aware of it today.
Signal is taking steps to address the emergence of quantum computing, and how that will affect encryption. This involves upgrading the Signal protocol with newer standards. More detail is available in the article, and is written to try and break down some of the concepts of Quantum computing and encryption to the lay-person
University of Maryland researches created a superconducting qbit that was able to retain information for 10 times longer than anything before it. This may not seem like much, but it's a huge step forward for quantum computing

Chinese Researchers Claim To Find Way To Break #Encryption Using #QuantumComputers - http://www.slashdot.org/story/409172
@briankrebs aso, gotcha. Agreed! I presume the goal is to maintain #anonymity of the C2 IOCs as they relate to the threat actors. If someone figures out how to use the processing power of the blockchain for purposeful intentions (good or bad), we're all in trouble. When will #quantumcomputers be commercially viable again? 
Might be our only hope for the future. #AIonQuantum
An entire class of security vulnerabilities of quantum computers! Foundational work. Too soon to complain? Anyway, best to consider the risks as soon as possible and include them in the architectural design sooner than later. Did we see it already decades ago? :) An issue is identified but it is not widely discussed (unclear if it’s being ignored) as here the cross-talk risk. Anyway, demonstrated on IBM Q. #cybersecurity #quantumcomputers https://dl.acm.org/doi/pdf/10.1145/3370748.3406570
Do we need anti-virus for quantum computers? Interesting theoretical issue. Sounds way ahead of the current times. On the other hand, with the advent of multi-tenacy cloud-available quantum devices, some security issues may come sooner than later “possible to perform a fault injection attack using crosstalk on quantum computers when a victim and attacker circuits are instantiated as co-tenants on the same quantum computer”. #cybersecurity #quantumcomputers https://arxiv.org/pdf/2203.02649.pdf
Another potential security design vulnerability of #QuantumComputers “readout error probability of a qubit is correlated with states of other qubits in the system … an adversary can exploit this correlation and infer the victim’s state by reading a qubit. The victim can be running algorithms with sensitive outputs and one of the several objectives of an adversary is to steal such sensitive data for financial gain”. Demonstrated on IBM Q. #cybersecurity https://arxiv.org/pdf/2104.05899.pdf
In Episode 1 we talked to Dr Yihui Quek about what #information means.
How do we understand the process of #learning, and what does it have to do with #QuantumComputers? Take a listen to find out!
How can #quantumcomputers be combined with conventional #supercomputing facilities to create the #quantumcomputing ecosystem of the future? 
In Episode 11 of #insideQuantum, we talk to Dr Alba Cervera-Lierta of the Barcelona Supercomputing Center, and co-ordinator of Quantum Spain, to find out!
La UE posa en marxa la primera tecnologia quàntica en sis centres d’arreu d’Europa.
