Quantum differential ghost microscopy

Understand

Quantum correlations become formidable tools for beating classical capacities of measurement.

• Preserving these advantages in practical systems, where experimental imperfections are unavoidable, is a challenge of the utmost importance.
• Here we propose and realize a quantum ghost imaging protocol able to compensate for the detrimental effect of detection noise and losses.
• This represents an important improvement as quantum correlations allow low brightness imaging, desirable for reducing the absorption dose.
