Abstract: On the premise of solving the problem in a specific situation, this paper aims at the laser marking machine to design and optimize the outline extraction of the two-dimensional composite ...

If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle the easiest pieces first. But this kind of sorting has a cost.

The original version of this story appeared in Quanta Magazine. One July afternoon in 2024, Ryan Williams set out to prove himself wrong. Two months had passed since he’d hit upon a startling ...

Quantum computers could crack a common data encryption technique once they have a million qubits, or quantum bits. While this is still well beyond the capabilities of existing quantum computers, this ...

What is the Q-Day prize? The Q-Day Prize is a challenge to make the Bitcoin network quantum resistant. On April 16, 2025, quantum computing-focused company Project 11 announced the “Q-Day Prize,” a ...

Researchers at FIU’s College of Engineering and Computing have developed an encryption algorithm to defend videos from attackers with access to the world's most powerful computers. The encryption ...

Quantum computing is still in the early stages of development, but it has proven to be an extremely powerful tool for various applications. While most demonstrations of their efficiency are limited to ...
