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

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

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 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 resource estimates suggest encryption barriers may fall faster than expected Reduced qubit requirements bring theoretical attacks closer to practical reality Bitcoin’s cryptographic ...

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

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

The amount of quantum computing power needed to crack a common data encryption technique has been reduced tenfold. This makes the encryption method even more vulnerable to quantum computers, which may ...

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 ...

A quantum attack on Bitcoin would crash its price before any theft settles, moving the real risk to confidential data.
