Eliciting Latent Predictions from Transformers with the Tuned Lens [PDF]
arXiv.org, 2023 We analyze transformers from the perspective of iterative inference, seeking to understand how model predictions are refined layer by layer. To do so, we train an affine probe for each block in a frozen pretrained model, making it possible to decode ...

Principles, Functions, and Applications of Optical Meta‐Lens
Advanced Optical Materials, 2021 A meta‐lens is an advanced flat optical device composed of artificial antennas. The amplitude, phase, and polarization of incident light can be engineered to satisfy the application requirements of meta‐lenses.

Quantifying computational advantage of Grover’s algorithm with the trace speed
Scientific Reports, 2021 Despite intensive research, the physical origin of the speed-up offered by quantum algorithms remains mysterious. No general physical quantity, like, for instance, entanglement, can be singled out as the essential useful resource.

Imaging with a gravitational lens: the geometric view [PDF]
MNRAS 527(1):1141-1145 (2024), 2023 We investigate imaging point sources with a monopole gravitational lens, such as the Solar Gravitational Lens in the geometric optics limit. We compute the light amplification of the lens used in conjunction with a telescope featuring a circular aperture that is placed in the focal region of the lens, compared to the amount of light collected by the ...
