With around 26,000 qubits, the encryption could be broken in a day, the researchers report in a paper submitted March 30 to arXiv.org. Another prevalent form of encryption, RSA–2048, would require 100 ...

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 ...

Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require nearly the resources anticipated just a year or two ago, two independently ...

Banks, governments and tech providers urged to upgrade security because current systems will soon be obsolete ...

Someday, somebody, somewhere will likely have a quantum computer capable of cracking the fragile codes that underpin every piece of data we exchange over the internet. We don’t know when. It could be ...

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 ...

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 ...

Google's new whitepaper says it could take only minutes for a quantum system to crack Bitcoin.

Bitcoin (CRYPTO: BTC) has a security problem that isn't going away, and it just got harder to dismiss. On March 31, Google's Quantum AI research team published a white paper showing that future ...

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 ...

Alphabet (Google) (NASDAQ:GOOG) has sounded a fresh alarm about the accelerating risks posed by quantum computers to the foundational security of Bitcoin and similar digital currencies. In a detailed ...

Chinese researchers say they have become the first people to use a quantum computer to compromise the type of password-based security system widely employed in critical industries such as defense.
