New approach for testing quantum supremacy
To test the ability of quantum computing devices to solve problems that classical computers practically cannot, researchers have looked into the idea of Gaussian boson sampling. This works by creating an environment where photons are introduced into a device and allowed to interact with each other for a given period of time. Prior research suggested that this is an intractable problem for todays’ computers as simulating photon location distribution over multiple samples would take a very long time. The EU-funded FrEQuMP project will conduct boson sampling by considering the frequency information encoded in photonic quantum states. They can then generate the desired coherent quantum state and demonstrate boson sampling with many photons, avoiding problems arising from photons leaking from the system.
