On December 9, Google launched Willow, its quantum chip with an influence of 105 qubits.

Other analysts, in settlement with Adam Back, perceive that this threat can be distant.
The debate over advances in quantum computing and its potential impression on cryptography continues to generate reflections.
Recently, CriptoNoticias reported that analysts have dismissed the theoretical threat that Google’s Willow quantum chip would characterize for the safety of Bitcoin (BTC) and different cryptographic methods, stating that present expertise is much from reaching the capability essential to compromise them.
However, on December 14, 2024, Chamath Palihapitiya, an engineer and enterprise capitalist, expressed the potential future impression of Willow on the algorithm of hashing Bitcoin’s SHA-256, which is the idea of the safety of this community.
According to his assertion, it might take roughly 8,000 Willow-like chips of Google to compromise SHA-256.
He argued that “we are in a window of 2 to 5 years” for cryptocurrency networks to should undertake algorithms. hash proof against quantum computing.
The response to Chamath Palihapitiya was instant
Hours later, Adam Back, co-founder of Blockstreams, attacked once more concerning the present lack of a threat for BTC on account of Google’s new quantum chip.
On this event, and in response to Palihapitiya’s statements, Back maintained in a publication in 1 and even 2 a long time away.
“No, you’ll be able to’t improve entangled qubits by connecting many 105-qubit chips. “We’re not even remotely close to having 1 million qubit computers this decade or probably the next either.”
Adam Back, co-founder of Blockstreams, a expertise firm linked to Bitcoin.
Back’s response refutes the thought of combining the facility of a number of quantum computing chips to create a system with entangled qubits (in English, entangled qubits), that’s, primary models of knowledge related in a large-scale quantum manner.
Furthermore, he emphasizes that attaining a quantum machine with 1 million absolutely purposeful and entangled qubits is very removed from present expertise, in all probability greater than 20 years away.
Following Adam Back’s response, one other X person requested the Blockstreams co-founder “how many qubits do you think would pose a threat to Bitcoin private keys?”
To reply that query, Adam turned to what, based on him, specialists on this subject say.
«Millions of utterly entangled bodily qubits, is what quantum computing specialists say. So we’re 5 orders of magnitude away. And on the fee of progress of the final 25 years, about 50 years away.”
Adam Back, co-founder of Blockstreams, a expertise firm linked to Bitcoin.
The declare that “we are 5 orders of magnitude away from reaching that capacity” signifies that the facility being measured at Willow is way lower than what’s required to place the safety of Bitcoin in danger.
In mathematical phrases, an “order of magnitude” refers to an element of 10. So when it’s stated that we’re 5 orders of magnitude under, we’re speaking a couple of distinction of 10 to the facility of 5 (10⁵), which is the same as 100,000.
In this case, based on Adam, the Willow chip would have a capability of 100,000 occasions under the extent required to interrupt the BTC encryption.
However, Back left room for the potential of disruptive technological advances that speed up that progress.
“Now, if something changes, like a technological advancement, that would be interesting. So this is just for context.”
Adam Back, co-founder of Blockstreams, a expertise firm linked to Bitcoin.
More opinions that doubt the present efficiency of Willow
Another analyst, below the pseudonym De Facto Monk in removed from compromising Bitcoin safety.
As he defined, making a quantum pc able to breaking the SHA-256 algorithm or Bitcoin’s non-public keys would require investing billions of {dollars} in a pc containing hundreds of thousands of utterly entangled qubits.
In the analyst’s opinion, the character of quantum calculations and present technical limitations make Willow unlikelyor every other comparable quantum expertise, represents a sensible menace to the Bitcoin community within the quick or medium time period.
Additionally, the one that expressed a place just like these of Adam and De Facto Monk, however slightly extra cautious concerning the longer term, was the bitcoiner analyst David Battaglia.
“In the long term, this (quantum computing) could become a threat, which is why it is crucial that Bitcoin evolves into a post-quantum scheme before such technology becomes available.”
David Battaglia, Bitcoin analyst.
In conclusion, as beforehand reported by CriptoNoticias, Adam’s new responses and opinions of specialists, the chance that Willow and quantum computing endanger Bitcoin cryptography would stay theoretical.
