This three-body interaction among the qudits (unrelated to the three-body problem of classical physics) drives the ...

As quantum computing develops, scientists are working to identify tasks for which quantum computers have a clear advantage over classical computers. So far, researchers have only pinpointed a ...

A team of researchers has published a comprehensive review in National Science Review, offering a systematic overview of the ...

In parallel, investigations into the design of reversible ternary full-adder/full-subtractor circuits have reported promising reductions in quantum cost and energy dissipation, emphasising the ...

Quantum computing is expected to leave classical computing in the dust when it comes to solving some of the world’s most fiendishly difficult problems. The best quantum machines today have one ...

This advance could lead to quantum computers that make fewer errors – if it can be replicated at a larger scale. Read more. Google's claim of quantum supremacy has been completely smashed.

Its quantum processor of that time, Sycamore, performed a task called random circuit sampling—generating quantum states on 53 qubits, corresponding to a computational state space of 2^{53 ...

Google was the first to declare quantum supremacy in 2019, describing its quantum computer's accomplishment as a "benchmark." The task it performed is called random circuit sampling, which is ...

Just as transistors replaced vacuum tubes in modern computing, Microsoft has created the “transistor for the quantum age” with its latest advances, said Chetan Nayak, a Microsoft technical ...
