Abstract: A magnetometer is provided for detecting a magnetic field of strength B using the Faraday effect. The magnetometer includes a photon emitter, a first polarizer, a prism, a second polarizer, a detector and an analyzer. The emitter projects an emitted light beam substantially parallel to the magnetic field and having wavelength λ. The prism has an interface surface and is composed of a Faraday medium having Verdet value V. The emitted light beam passes through the first polarizer and then the prism, exiting from the interface surface making an incident angle θ0 to normal of the surface and then refracting into a secondary medium as first and second circularly polarized light beams that are separated by a small angular divergence δ. These polarized light beams have average refraction angle θ to the normal and pass through a post-selection polarizer before the detector measures a weak value Aw of a photon having “which path” operator  associated with the polarized light beams. The magnetic field strength is determined as B ≈ - 2  ɛ   A w  π   n 0  cos   θ V   λsin   θ 0 . The parameters include n0 as index of refraction of the secondary medium, and ε as amplification factor. The pointer rotation angle Aw can be expressed as A w = ( θ + - θ - )  cos   ɛ + [ ( θ + + θ - ) - 2  θ 0 ]  sin   ɛ 2   sin   ɛ in which θ+ and θ− are respectively right- and left-polarized refraction angles with the average refraction angle such that θ = 1 2  ( θ + + θ - ) . The pointer rotation angle Aw can be approximated as Aw≈δ/2ε when 0

Abstract: A Mach-Zehnder interferometer (MZI) is provided to receive a coherent input photon in an initial pointer state for producing a continuously variable “faux qubit” in a magic state. The MZI apparatus includes first and second ports, first and second beam-splitters, first and second mirrors, and a modular interaction operator. The emitter produces an input coherent photon in an initial pointer state along an emission direction. The first and second ports are respectively disposed parallel and perpendicular to the emission direction. The first and second beam-splitters are disposed respectively collinearly with the emission direction and between the first and second ports parallel to and offset from the emission direction. The first and second mirrors are disposed respectively offset from and collinearly with the emission direction. The modular interaction operator is disposed between the first mirror and the second beam-splitter for measuring interaction therebetween to generate a post-selected magic state photon.

Abstract: An m-dimensional memory with m-1 dimensional hyperplane access. Random acs memory (RAM) circuits are arranged in a plurality of groups for storing data words corresponding to vertices of an m-dimensional lattice. Each vertex of the lattice is defined by an m-tuple. The minimum number of RAM circuits required to realize the memory architecture of the present invention is based upon the size of the lattice and the distribution of the data words in memory is based upon the m-tuples used to define the lattice.

Abstract: A method for relational database scheme design with the aid of a digital puter for a database having attributes A.sub.i, i=1 to n and relational schemes R.sub.j, j=1 to m. Each relational scheme R.sub.j is a non-empty subset of the attributes A.sub.i. The method detects any scheme that is non-acyclic in a simple manner that is easily adapted to a digital computer environment. The resulting relational database scheme design is thereby prevented from being non-acyclic.

Abstract: An optical biosensor is provided for detecting a bio-molecular sample by Goos-Hänchen (GH) enhancement of Aharonov-Albert-Vaidman (AAV) amplification to a surface plasmon resonance (SPR) detector. The sensor includes pre- and post-selection polarizers respectively upstream and downstream of a right-isosceles prism with a metal film and a liquid medium disposed on a diagonal side of the prism. Laser light passes through the first polarizer, reflects at the film, passes through the second polarizer and is detected with a shift determined by a pointer estimator to indicate the sample.

Abstract: A quantum dynamical non-locality device is provided for establishing a photon traveling along a path in a binary state. The device includes twin Mach-Zehnder interferometer (MZI), a shutter and a detector. The twin MZI includes first and second right-isosceles triangle prisms, corresponding first and second trombone mirrors, and corresponding first and second spacers. The prisms join at a beam-splitter interface. The mirrors reflect the photon by an offset substantially perpendicular to photon's travel direction. The spacers are respectively disposed between their respective prisms and mirrors to produce corresponding spatial gaps. The path through the prisms includes traversing spacers and gaps. The detector detects a quantum state of the photon after passing the prisms and the mirrors. The shutter switches to one of disposed within and removed therefrom the first gap. The shutter shifts said quantum state of the photon.

Abstract: A method for synchronizing a master clock to a slave clock located in master and slave devices communicating with one another via a laser signal beam and a communications channel, each of the devices including a homodyne detector for determining a respective correlation pattern with respect to a phase tuned local oscillator includes steps for recording master and slave correlation patterns while the signal beam cycles between first and second operating modes, transmitting the master correlation pattern and associated first and second times at which the signal beam shifted between the first and second operating modes and between the second and first operating modes over the communications channel, comparing a portion of the master correlation pattern between the first and second times to the slave correlation pattern to thereby determine the time offset between the master and slave correlation patterns, and applying the time offset to the slave clock. A corresponding clock synchronization system is also described.
