Russia Unveils Prototype of 50-Qubit Quantum Computer

Scientists from Moscow University and the Russian Quantum Center have developed the country’s first prototype of a 50-qubit quantum computer. It was tested on December 19, according to the MSU website. The prototype is based on single neutral rubidium atoms, which are captured by optical tweezers—focused laser beams. A qubit is encoded in the internal […]

Adam Back: Quantum Computing Will Strengthen Bitcoin

Advancements in quantum computing are more likely to bolster Bitcoin than to undermine it, according to renowned cypherpunk and cryptographer Adam Back. in all likelihood the hash-based PQ scheme will never be used. because PQ is likely still several decades out at least. and and PQ signature research will eventually produce conservative well reviewed more […]

Quantum Computers Could Crack Bitcoin in Five Years, Scientist Warns

Commercial quantum computers may be able to crack the elliptic curve keys securing Bitcoin wallets in about five years. This perspective was shared by Pierre-Luc Dallaire-Demers, a scientist from the University of Calgary, in a conversation with DLNews. The expert refers to ECDSA 256 encryption, which protects addresses and signs transactions using pairs of public […]

Add the cat: why Bitcoin’s potential OP_CAT upgrade matters

Upgrades to the bitcoin network are infrequent—the last soft fork, Taproot, was activated in November 2021. By comparison, since then Ethereum has shipped Shapella, Dencun and The Merge, with the Pectra upgrade already slated for the first quarter of 2025. Meanwhile, the community is only debating the possible implementation of an improvement proposal dubbed OP_CAT […]

Quantum computers: who will bask in the glow of the analogue–digital chandelier?

Quantum computers have long inspired both hope and anxiety. Optimists expect them to propel computing into a new era, tackling problems beyond the reach of today’s most powerful machines. Pessimists counter that, for ordinary users, all those qubits dangling in “chandeliers” will bring little besides new challenges for cryptography and data protection. For ForkLog readers, […]
