President Trump Signs Two Executive Orders on Quantum Technology

President Donald J. Trump has signed two Executive Orders to cement American leadership in the quantum era. The first order, "Securing the Nation Against Advanced Cryptographic Attacks," aims to protect the nation from cryptographic attacks by transitioning federal agencies to Post-Quantum Cryptography. The second order, "Ushering in the Next Frontier of Quantum Innovation," focuses on commercialization and scientific discovery. Key provisions include a nationwide PQC migration, a quantum computer initiative, and workforce development strategies. Federal agencies must designate PQC migration leads and transition to PQC by 2030 and 2031.

💡 By establishing a strict timeline for PQC migration, the US government can stay ahead of potential cryptographic threats from foreign adversaries. The orders' focus on quantum innovation also positions the US to lead in the development of groundbreaking technologies.

Fraunhofer IPMS Unveils Quantum Random Number Generator to Deliver True Randomness

Fraunhofer IPMS has unveiled Q-Dice, a quantum random number generator that produces true random numbers at rates above 4 Gbit/s for security-critical applications. The system has been evaluated under BSI AIS 20/31 and NIST SP 800-22 testing frameworks and is classified at EAL 3 and PTG 3. Q-Dice is available as a 19-inch rack-mounted hardware appliance or through an online Entropy-as-a-Service platform for cloud-based access to quantum-generated randomness.

💡 The emergence of Q-Dice highlights the growing importance of quantum-level security in modern cryptographic systems, where weak or predictable random number generators can introduce vulnerabilities in encryption and authentication. By leveraging quantum vacuum fluctuations, Q-Dice provides a robust solution for generating true randomness, which is essential for secure communication, data encryption, and authentication.
