In search of the theory of gravity

As new and powerful telescopes gather new data about the universe, they reveal the limits of older theories. Credit: Shutterstock Einstein’s theory of gravity—general relativity—has been very successful for more…

Can cloud-based quantum computing really offer a quantum advantage?

The input to the service is a user-designed quantum circuit. The service begins with qubit allocation, which relates physical qubits to a designed circuit. An implementation of the circuit is…
