However, it is not necessary to use fancy quantum cryptography technology such as entanglement to avoid the looming quantum ...

Starware’s CPO has proposed a solution that would make Bitcoin users make quantum-safe transactions today without protocol changes, though high costs make it impractical for everyday use.

One paper finds that attacking the bitcoin blockchain through quantum mining would demand the energy output of a star.

Abstract: Shor's algorithm is one of the most prominent quantum algorithms, yet finding efficient implementations remains an active research challenge. While many approaches focus on low-level modular ...

Why it matters: One of the greatest risks of quantum computing is its potential to break many of the cryptographic protocols that keeps the internet safe today. Thankfully, quantum is still fairly ...

Google on Friday unveiled its plan for its Chrome browser to secure HTTPS certificates against quantum computer attacks without breaking the Internet. The objective is a tall order. The ...

John Martinis is a hardware guy. He prefers the nitty-gritty of doing physics in the lab over the idealised world of textbooks. But you couldn’t write the quantum computing history books without him: ...

We now have our own terminal tournament featuring a competition for data scientists, analysts, and engineers. Iran's president issues open letter to the American public Dietitians say you shouldn't ...

The original version of this story appeared in Quanta Magazine. Imagine a town with two widget merchants. Customers prefer cheaper widgets, so the merchants must compete to set the lowest price.

Quantum computing’s accelerating breakthroughs are forcing the crypto sector to confront a long-anticipated question. How long before quantum machines can break Bitcoin security? Blockchain analytics ...
