How quantum computers actually work, in plain language To understand why quantum machines are so dangerous to encryption, I start with how different they are from the laptops on our desks. Classical ...

Digital secrets are protected by encryption, which converts meaningful data into an unintelligible form. If quantum computers ...

Quantum computing advances raise concerns over 10,000 qubits breaking P‑256 encryption using Shor’s algorithm, driving ...

Online data is generally pretty secure. Assuming everyone is careful with passwords and other protections, you can think of it as being locked in a vault so strong that even all the world’s ...

The day when a quantum computer can crack commonly used forms of encryption is drawing closer. The world isn’t prepared, ...

Quantum computers powerful enough to break widely used public-key encryption aren’t here yet, but migration won’t be as simple as swapping in a new tool.

Quantum computing encryption is reshaping how we think about digital security in a world built on encrypted communication. Today's systems rely on mathematical complexity, but emerging quantum ...

About eight years ago, toward the end of a panel I was moderating on cybersecurity, I turned to the panelists and asked them to tell me what to expect when quantum computing would come online. I got ...

Quantum power is calculated in qubits. Every 10 qubits supports 1,024 computations, giving hackers 1,024 times the power to break encryption in one swoop, Steward illustrated. There are now machines ...

Quantum computing could lead to revolutions in cryptography, materials design and telecommunications. But fulfilling those promises could be many years away ...

Quantum computers should be powerful enough to crack Bitcoin’s security features—by instantly solving the mining mechanism or guessing wallet passwords by brute force—a few years after 2030, according ...

This research might also help pave the way for the quantum internet and other quantum systems in 40-50 years. Computer scientists with Toshiba Europe recently distributed quantum encryption keys ...
