You may not have realized it yet, but the United Nations has declared 2025 the International Year of Quantum Science and ...

The promise of so-called “quantum advantage” is simple. By harnessing the counterintuitive rules of quantum mechanics, ...

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre ...

Physicists are a step closer to using quantum computers for simulations that are beyond the ability of any ordinary computers ...

Google says they have reached 'quantum supremacy' with their quantum computer 'Sycamore'. Nature reporter Elizabeth Gibney explains what this means, why IBM disagree, and the significance for ...

Google has been challenged by an algorithm that could solve a problem faster than its Sycamore quantum computer, which it used in 2019 to claim the first example of “quantum supremacy” – the ...

Together, this group used Google's Sycamore quantum computing hardware to program 20 "spins" using the quantum version of a classical computer's bits of information, known as qubits.

Google's Sycamore quantum computer was the first to demonstrate quantum supremacy – solving calculations that would be unfeasible on a classical computer – but now ordinary machines have ...

This work presents an energy-efficient classical simulation algorithm using GPUs that outperforms Google's Sycamore processor in speed and energy consumption, challenging the claim of quantum ...

For comparison, Google’s Sycamore quantum processor uses 70 qubits ... the coldest temperature possible in nature. “To implement a larger number of components, thermal heat is a very difficult problem ...

The research, published in the academic journal Nature, represents an essential step in quantum computing and demonstrates its potential by directly simulating fundamental interactions with Google ...
