Running quantum software on a classical computer Date: August 3, 2021 Source: Ecole Polytechnique Fédérale de Lausanne Summary: Physicists have introduced an approach for simulating the quantum ...

These problems, the authors show, can be solved on a quantum computer in what's called polynomial time, where the number of qubits is raised to a constant power (denoted n k).

Earlier this year, researchers at the Flatiron Institute's Center for Computational Quantum Physics (CCQ) announced that they had successfully used a classical computer and sophisticated ...

For the first time, a quantum computer made from photons—particles of light—has outperformed even the fastest classical supercomputers. Physicists led by Chao-Yang Lu and Jian-Wei Pan, both at ...

Over time, the increased entanglement of the system makes it hard for a classical computer to simulate. However, in a closed system, there’s only so much energy to go around.

A close-up look at D-Wave’s Advantage2 annealing quantum computer prototype. Since February 2024, D- Wave customers have run nearly 9.5 million problems on the Advantage2 annealing quantum ...

It’s time-consuming to convert classical computer data from places like social networks, the stock market, or internal company systems into the quantum state for processing.

Toward a quantum computer that calculates molecular energy Date: March 16, 2022 Source: Columbia University Summary: Researchers have developed an algorithm that uses the most quantum bits to date ...
