Quantum detector tomography of a time-multiplexed superconducting nanowire single-photon detector at telecom wavelengths [PDF]

, 2013
Superconducting nanowire single-photon detectors (SNSPDs) are widely used in telecom wavelength optical quantum information science applications. Quantum detector tomography allows the positive-operator-valued measure (POVM) of a single-photon detector ...

Photoacoustic Tomography: In Vivo Imaging from Organelles to Organs

Science, 2012
Lights, Sound, Images Optical microscopy can readily image thin samples such as cells, but thicker samples, such as tissue, are more difficult to image directly, because of the multiple scattering of light. Wang and Hu (p.

Optical coherence tomography in archaeological and conservation science - a new emerging field [PDF]

, 2008
There has been a long tradition of applying biomedical imaging techniques to the examination of historical artefacts, owing to similar demands for non-invasive methods in both fields. Optical Coherence Tomography (OCT) is no exception.

Optical coherence tomography angiography

Progress in retinal and eye research, 2017
Optical coherence tomography (OCT) was one of the biggest advances in ophthalmic imaging. Building on that platform, OCT angiography (OCTA) provides depth resolved images of blood flow in the retina and choroid with levels of detail far exceeding that ...

Shadow tomography of quantum states [PDF]

Electron. Colloquium Comput. Complex., 2017
We introduce the problem of *shadow tomography*: given an unknown D-dimensional quantum mixed state ρ, as well as known two-outcome measurements E1,…,EM, estimate the probability that Ei accepts ρ, to within additive error ε, for each of the M ...
