#Ordinateur #quantique : l'exploit des #physiciens qui ont réussi à "dompter" une onde qui s'évapore en un éclair

Les #magnons vont pouvoir agir comme un véritable « #bus #quantique », une autoroute de l’information capable de connecter des centaines de #qubits simultanément le long d’un chemin partagé.

#Quantencomputer wird realistisch: Nachdem das BSI warnte, klassische asymmetrische Verschlüsselungsverfahren bis Ende 2031 nicht mehr zu verwenden, haben Sicherheitsforscher ein Paper publiziert, in dem gezeigt wird, dass Shors Algorithmus, mit dem sich gängige Public-Key-Kryptografie wie ECC-256 und RSA-2048 brechen lässt – mit deutlich weniger physischen #Qubits ausführbar ist als bislang angenommen - nämlich anstelle von Millionen nur 30.000. Das wäre eine Revolution:

Weekend reading with TechAptitude!

Quantum networks hold the potential to enable fundamentally new capabilities, including ultra-secure communication with unbreakable encryption, distributed quantum computing, and hold out the promise of creating a “Quantum Internet”. Check it out!

https://journals.aps.org/prl/abstract/10.1103/y4y1-1ll6 Well… that’s not something I expected to read today.

A new Physical Review Letters paper claims a way to effectively clone qubits.

The trick: the copies are quantum-encrypted. You can make many of them, but the decryption key only works once — so at any moment only one usable quantum state exists, keeping the no-cloning theorem intact.

Interesting idea for quantum backups and distributed quantum data.

Probably worth investigating more deeply…
adding it to the already far too long TODO list. #QuantumPhysics #QuantumInformation #Qubits #QuantumComputing #Physics #AcademicMastodon

The latest TechAptitude post explores the highly complex and critical space of Quantum Memory. Quantum Memory performs the delicate balance of storing the quantum state of a photon or other entangled particle without destroying the quantum information of that particle.
