摘要： In one embodiment, an apparatus comprises an optical system with multiple detectors and a processor. The optical system is configured to produce images of an optical source in a first dimension and a second dimension substantially orthogonal to the first dimension at each detector at a given time. Each image from the images is based on an interference of an emission from the optical source in a first direction and an emission from the optical source in a second direction different from the first direction. The processor is configured to calculate a position in a third dimension based on the images. The third dimension is substantially orthogonal to the first dimension and the second dimension.

摘要： Incoming data from, for example, an array of detectors, may be received. A dynamical system may be initialized corresponding to a modality of the incoming data so that a measurement probe based on the initialized dynamical system may be generated. Such a measurement probe may be injected into a quantum mechanical system so that it may be determined whether the injection of the measurement probe into the quantum mechanical system results in a collapse of the quantum mechanical system. Thereafter, it may be determined that a signal is present within the incoming data if the quantum mechanical system collapses. Related methods, apparatuses, systems, and computer-program products are also described.

According to one or more embodiments, the method may comprise reading out at the end of successive interrogation sub-intervals (T i ) intermediate error signals corresponding to the approximate phase difference (Õ) between the phase of the LO signal and that of the quantum system, using coherence preserving measurements; shifting at the end of each interrogation sub-intervals (T i ) the phase of the local oscillator signal, by a known correction value (Õ (i) FB ) so as to avoid that the phase difference approaches the limit of the inversion region; reading out a final phase difference (Õ f ) between the phase of the prestabilized oscillator signal and that of the quantum system using a precise measurement with no restriction on the destruction; reconstructing a total phase difference over the extended interrogation interval, as the sum of the final phase difference (Õ f ) and the opposite of all the applied phase corrections - ˆ‘ i Æ FB i .

摘要： The device is based on a cross-correlator which measures the signal between a pair of oppositely chirped laser pulses. Two laser pulses, one with a positive chirp and one with a negative chirp, are mixed on a beamsplitter. The two resulting beams pass through a reference or a sample arm and are subsequently mixed on a non-lmear crystal. The signal from the interferometer is the sum frequency generation produced in that crystal. The reference arm contains a moveable delay which is used to change the relative timing of the two beams in the interferometer. The sum frequency generation in the narrow band of frequencies is the signal from the device and is measured as a function of the delay. Alternatively, a pure dispersive phase shift could be used in place of the two laser pulses.
