Quantum Communications and Quantum Imaging XVI, 2018
We study the problem of quantum temporal imaging in the case where the time lens is implemented by a sum frequency generation nonlinear process. We consider the general case where the time lens is characterized by a finite aperture and a not-perfect phase-matching in a regime close to 100% conversion efficiency.

We analyze a scheme consisting of an optical parametric amplifier and two imaging lenses. From an off-axis input image such a system creates two quantum entangled output images, signal and idler, symmetrical with respect to the optical axis of the scheme.

In this chapter, the discussion is started by dividing quantum image security techniques into the two categories of cryptography and information hiding. Specifically, the background and advances of quantum image scrambling, encryption, watermarking, and steganography are discussed. In addition to the fast computing speed brought by parallel computation,

We propose two different active imaging schemes that are secure against manipulation of the imaging photons by the object being imaged. These schemes are based on the BB84 and Ekert protocols used in QKD.
