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 ...

While post-quantum security standards and technical solutions are rapidly advancing, Quantus’ Chris Smith argues that Bitcoin ...

However, Quantum Day (Q-Day) is different. Q-Day is the moment a quantum computer becomes powerful enough to break the ...

The very prospect of the quantum apocalypse has driven various stakeholders to consider what that could be like and how to prepare. For instance, in 2015, the U.S. Natio ...

In December 2024, a team at Google published a result in Nature that physicists had been chasing for nearly three decades: a surface-code quantum error correction experiment that crossed below the ...

Somewhere on a blockchain right now, a Bitcoin address that last moved coins in 2015 is sitting with its public key fully exposed, waiting for its owner to return. That owner may have years to act, or ...

A new quantum-inspired algorithm has cracked a problem so massive that conventional supercomputers struggle to even approach ...

The day when a quantum computer can crack commonly used forms of encryption is drawing closer. The world isn’t prepared, ...

Researchers from the group of theoretical physicist Hans Briegel have collaborated with NVIDIA to develop an AI method that ...

Michael Shaulov argued that changing to a post-quantum cryptographic signature scheme is “not a technical challenge” for ...

Quantum information science is now a fast-growing field, but when 2025 ACM A.M. Turing Award recipients Charles H. Bennett ...
