There are provided optical quantum logic gate (OQLG) characterized by 2n∗2n unitary matrix and method of operating thereof. OQLG comprises first optical structure comprising 2n optically-coupled cores with one-to-one correspondence to input binary values specified by the matrix and second optical structure optically connected to the first optical structure and comprising 2n amplifying channels corresponding to the 2n cores. The first optical structure is configured to receive photons in binary fundamental quantum states (FQSs) representing input binary values specified by the matrix and to inject the received photons in the 2n cores, use optical coupling between the cores to mix the injected photons, and output photons into the second optical structure, wherein outputted mixed photons correspond to output binary values specified by the matrix. The second optical structure is configured to amplify, in a controllable manner, photons in the amplifying channels with preserving the FQSs and relative quantities of photons with different FQSs.

A photonic system is described that employs, e.g., a first laser generating a first optical beam at a first wavelength and a second laser generating a second optical beam at a second, different wavelength. The photonic system also includes a resonator, e.g., a whispering gallery mode (WGM) resonator, configured to receive a portion of the first optical beam and a portion of the second optical beam. The first laser is locked to a first mode of the resonator using either self-injection locking (SIL) or Pound-Drever-Hall (PDH) locking. The second laser is also locked to a second mode of the resonator using either SIL or a PDH. The first and second wavelengths (frequencies) may differ from one another by a few gigahertz (GHz) or, e.g., larger than 10 terahertz (THz). The system thus allows diverse wavelengths to be locked to one another.

This disclosure provides systems, methods, and devices for image signal processing that support improved image capture during variable optical zoom (VOZ) system zoom level transitions. In a first aspect, a method of image processing includes determining a command to transition from a first zoom level at which a lens is in a first position to a second zoom level at which the lens is in a second position. The VOZ system may be controlled to move the lens from the first position to a third position between the first position and the second position. A first image frame captured with the lens in the third position may be received, and a first digital zoom may be applied to the first image according to the second zoom level. Other aspects and features are also claimed and described.

To provide an optical quantum logic gate (OQLG) and a method of operating it.SOLUTION: An OQLG comprises first optical structure including 2n optically-coupled cores with one-to-one correspondence to input binary values specified by the matrix and second optical structure optically connected to the first optical structure and including 2n amplifying channels corresponding to the 2n cores. The first optical structure receives photons in binary fundamental quantum states representing input binary values specified by the matrix and injects the received photons in the 2n cores 211 and 212, uses optical coupling between the cores to mix the injected photons, and outputs the photons to the second optical structure. The output mixed photons correspond to output binary values specified by the matrix. The second optical structure amplifies photons in the amplifying channels in a controllable manner while preserving the binary fundamental quantum states and relative quantities of photons having different binary fundamental quantum states.SELECTED DRAWING: Figure 2
