IBM scientists entangled 120 qubits in a single coherent “cat state,” a record-breaking feat in quantum computing.

Quantum computing may prove to be an existential threat to Bitcoin, but human panic and slow preparation are bigger ...

Breakthroughs from Google, Caltech, and IBM have reignited debate over “Q-Day,” when quantum computers could break Bitcoin’s cryptography.

Bitcoin relies on several algorithms to secure the coin from theft. Prominent among these is the Elliptic Curve Digital Signature Algorithm (ECDSA). An ECDSA employs asymmetric encryption to generate ...

Here’s why Quantum experts are warning that Bitcoin’s encryption could be broken by 2028 as quantum computing accelerates.

According to the model, approximately 1,673 logical qubits would be sufficient to derive Bitcoin private keys from exposed public keys.

Google Quantum AI revealed that its Willow processor achieved a milestone in quantum computing with the Quantum Echoes algorithm.

According to one of the world’s leading cryptographers, Bitcoin’s elliptic curve could have a secret backdoor, invalidating all underlying security. A Bitcoin public key is created by applying ...

The recent Project Eleven bounty for quantum computers cracking cryptographic keys is a joke. It provides no serious incentive at all. Recently, Project Eleven (a quantum computing research group) ...

As far as open-source protocols go, one area in which Bitcoin is unique is the sheer difficulty of making any changes to the protocol. Unlike most other protocols, where features can be added, ...
