Sample-Efficient Device-Independent Quantum State Verification and Certification

The Dakic-group have published a new paper in PRX QUANTUM!

Correct and reliable operation of quantum devices is one of the most important milestones to be achieved for practical applications of quantum technologies. At the current state of the art, this is a difficult task due to various practical shortcomings such as noise and decoherence, and the lack of perfect control and manipulation. A reliable verification theory that fully captures these effects is still under development.

In the new work published in PRX QUANTUM, our team has developed a new verification and certification technique that achieves optimal efficiency in a device-independent regime without the usual assumptions about trusted devices and measurements. The popular summary of the results can be found on the journal’s website:
