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 ...

Traditional encryption methods have long been vulnerable to quantum computers, but two new analyses suggest a capable enough machine may be built much sooner than previously thought ...

If you’re picturing quantum computing as a giant red button that suddenly shuts off the internet, the reality is a little less theatrical and a lot more technical than that. The main danger isn't that ...

Project Eleven, a quantum security research company, awarded a prize to researcher Giancarlo Lelli for using a quantum computer to break a 15-bit elliptic-curve key — a small-scale version of the same ...

Google LLC today published a paper that indicates a quantum computer with 500,000 qubits could be used to steal cryptocurrency. The cybersecurity risks posed by quantum computers were already ...

With around 26,000 qubits, the encryption could be broken in a day, the researchers report in a paper submitted March 30 to ...

The 50-page paper concludes that while today’s blockchains remain secure, a future “fault-tolerant quantum computer” capable ...

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 ...

Cardano founder Charles Hoskinson has raised concerns about the pace of quantum computing development and its possible ...

The day when a quantum computer manages to break common encryption, or Q-Day, is fast approaching, and the world is not close ...

Google published a paper on March 31 that states that Bitcoin's cryptography could be impacted by quantum computing sooner than previously stated.
