Described herein are systems and methods for reducing image aberrations in high magnification photography with partial reflectors. In particular, by an imaging device or camera that is built into or is included in a cell phone, smart phone, tablet, laptop or any other mobile device. The systems and methods include a light passing through a lens, a portion of said light then undergoes a number of partial reflections in-between two partial reflectors, and a portion of said light then reaches an imaging sensor. The partial reflections enable a longer light path to reach the imaging sensor, thus enabling a longer focal length to be used, which enables higher magnification. Described are methods and embodiments to select the physical parameters of optical elements in systems with partial reflectors, in order to create images with reduced image aberrations.

Methods and systems for image correction and processing in high-magnification photography exploiting partial reflectors

Imaging systems and methods are provided for taking high-magnification photographs confined to a small physical volume. In some embodiments the system is composed of at least one lens, one or more partially reflective elements, and a sensor. The partial reflectors reflect a portion of the light back and forth between them to allow a long path length for a portion of the light from the lens to the sensor which enables a high magnification.

Disclosed embodiments enable determining and monitoring the location of at least one particle in a subject's body, as well as the status of a local environment within the body where the at least one particle is located.

Differential phase shift (DPS) quantum key distribution (QKD) is provided, where the average number of photons per transmitted pulse is predetermined such that the secure key generation rate is maximal or nearly maximal, given other system parameters. These parameters include detector quantum efficiency, channel transmittance and pulse spacing (or clock rate). Additional system parameters that can optionally be included in the optimization include baseline error rate, sifted key error rate, detector dead time, detector dark count rate, and error correction algorithm performance factor. The security analysis leading to these results is based on consideration of a hybrid beam splitter and intercept-resend attack.

Differential phase shift keying quantum key distribution

A normally opaque waveguide interacting with a drop-filter cavity can be switched to a transparent state when the drop filter is also coupled to a dipole. This dipole induced transparency may be obtained even when the vacuum Rabi frequency of the dipole is much less than the cavity decay rate. The condition for transparency is a large Purcell factor. Dipole induced transparency can be used in quantum repeaters for long distance quantum communication.

A system and method for quantum key distribution uses a regulated single-photon source to sequentially generate a first photon and a second photon separated by a time interval &#x394;t. The two photons are directed through a beam splitter that directs each photon to one of two transmission lines, which lead to two respective receivers. When one of the photons arrives at a receiver, it passes through an interferometer. One arm of the interferometer has a path length longer than the other arm by an amount equivalent to a photon time delay of &#x394;t. The photon is then detected in one of three time slots by one of two single-photon detectors associated with each of the two interferometer outputs. Due to quantum-mechanical entanglement in phase and time between the two photons, the receivers can determine a secret quantum key bit value from their measurements of the time slots in which the photons arrived, or of the detectors where the photons arrived.
