US Must Pair Quantum Research With Industrial Strategy, UCLA Physicist Argues

The post-quantum EO is an important milestone. Now it’s time to get to work

Sắc lệnh hành pháp 14409 của Mỹ yêu cầu các cơ quan liên bang và nhà thầu phải chuyển sang mã hóa hậu lượng tử (PQC) vào năm 2030 và xác thực hậu lượng tử vào năm 2031, nhằm ngăn chặn các cuộc tấn công "thu thập giờ đây giải mã sau". Cloudflare khuyến nghị cần làm rõ tiêu chuẩn "chuyển đổi", ưu tiên khả năng thích ứng mật mã (crypto agility) và thúc đẩy sự thống nhất toàn cầu về thuật toán NIST để tránh phân mảnh.

Lập trình viên nên đọc bài này để hiểu cách chuyển đổi sang các giải pháp mã hóa chống lượng tử (post-quantum) không chỉ là một yêu cầu pháp lý mà là một chiến lược bảo mật cấp hệ thống, giúp bảo vệ ứng dụng của bạn trước các mối đe dọa tương lai từ máy tính lượng tử trong thời gian ngắn nhất.

JIC Venture Growth Investments And Toyota Invention Partners Join Yaqumo Seed Extension Round

Japanese neutral-atom quantum computing startup Yaqumo has closed a seed extension round with new investors JIC Venture Growth Investments (a government-backed Japanese VC with ~JPY 320 billion across two funds) and Toyota Invention Partners (Toyota's strategic investment arm with a JPY 100 billion pool). Both investments are firsts in quantum computing hardware for their respective firms. Yaqumo previously raised from Quantonation and Alumni Ventures. The new backing is intended to deepen ties with Japanese government institutions, explore manufacturing and mobility applications with Toyota, and accelerate commercialization of neutral-atom quantum computers originating from Japan.

Verifier-initiated quantum message-authentication via quantum zero-knowledge proofs

On-demand authentication is critical for scalable quantum systems, yet many existing quantum signature and message-authentication schemes are signer-initiated, requiring advance distribution of authentication material even when no verification occurs. We introduce verifier-initiated quantum digital signatures (VIQDS), in which the verifier requests authentication only when needed and the signer responds once; after issuance, verification proceeds without further interaction. Practically, shifting authentication to a verifier-driven, on-demand workflow reduces avoidable communication and storage overhead and aligns with deployments where verification is sporadic, such as distributed services and audit-oriented infrastructures. Our approach leverages quantum zero-knowledge techniques so that verification reveals nothing about the signer’s secret key beyond the fact that the signature is valid. We present a general conversion principle from suitable quantum proof protocols to VIQDS, together with a concrete realization based on elementary qubit platforms. Here, we show information-theoretic security against forgery and privacy against curious verifiers without computational hardness assumptions. The authors introduce a verifier-initiated quantum message-authentication method, in which authentication is requested only when needed. Their approach uses quantum zero knowledge techniques to protect information about the signer’s secret key while providing information-theoretic security against forgery
