ABSTRACT: The author has recently presented the Single-Iteration Quantum Search Algorithm, which achieves amplitude-amplification with exactly one oracle call and one π/4 rotation [1]. For N = 2n ...

A lot has been made about a post-quantum computer future in which traditional encryption methods have suddenly been rendered obsolete. With this terrifying idea in mind, it’s reassuring to see some ...

With growing focus on the existential threat quantum computing poses to some of the most crucial and widely used forms of encryption, cryptography engineer Filippo Valsorda wants to make one thing ...

Bitcoin transactions could be resistant to quantum attacks without changing the network’s core rules, a new proposal contends. A new research proposal claims it can make Bitcoin transactions resistant ...

Quantum computers pose a genuine long-term risk to bitcoin, but current fears often conflate wallet vulnerabilities with largely impractical threats to mining. New research finds that a quantum 51% ...

First proof-of-concept To put their approach to the test, the researchers implemented Grover's quantum search algorithm fault-tolerantly on three logical qubits encoded across eight physical qubits of ...

ABSTRACT: Grover’s algorithm is widely celebrated as providing quadratic quantum speedup for unsorted database search, forming the theoretical foundation for numerous claimed quantum advantages in ...

Understanding quantum computing, from qubits science and tech breakthroughs to future quantum applications, and discovering how close we are to real-world use cases Pixabay, geralt Quantum computing ...

On classical computers, brute-force attacks on symmetric encryptions require O(N) op erations. However, [1] Grover’s algorithm provides a quadratic speedup on quantum com puters, requiring only O(√N).

Teleportation is a reality in 2025 — well, at least for quantum computers. In February 2025, Oxford University demonstrated the teleportation of quantum data from one independent quantum processor to ...
