Caltech professor of chemistry Sandeep Sharma and colleagues from IBM and the RIKEN Center for Computational Science in Japan ...

A research team has achieved the holy grail of quantum computing: an exponential speedup that’s unconditional. By using ...

The classical computer typically handles tasks like optimization and data preparation, while the quantum computer performs the computationally expensive calculations that involve quantum states.

A quantum computer works in a totally different way from a classical computer. Quantum bits or 'qubits' can exist in a superposition state of both zero and one simultaneously. This means that a ...

He calls the back and forth between the quantum- and classical-computing communities a “symbiotic relationship,” in which the two sides challenge each other by developing ever-more sophisticated ...

As scientists work to figure out where quantum computers might have an edge, they’re coming up with complex problems that test the limits of classical and quantum computers.

These functions involve calculations that are too complex for even a quantum computer to crack, but with a “trapdoor” that allows a classical machine with the correct key to solve them easily. The ...

Evidence that a quantum computer can solve a problem faster than a classical computer – quantum advantage – is therefore a key measure of success. The first claim of quantum advantage came in 2019, ...

In 2002, Jozsa helped work out a simple process for using a classical computer to simulate a quantum “circuit,” which is a specific series of operations performed on qubits. If you gave the classical ...

“This work is an important step toward sharpening that understanding, with clear evidence of where our quantum computer was able to outperform classical methods.

Microsoft is showing off some of the work it has been ... Researchers will soon be able to use Quantinuum hardware available in Azure to test this and then have the classical computer react ...

To somewhat work around these limitations, IBM has now pitched the idea of a hybrid quantum-classical computer (marketed as ‘quantum-centric supercomputing’), which as the name suggests ...
