  • Patent number: 10747087
    Abstract: Methods and devices are disclosed for implementing quantum information processing based on electron spins in semiconductor and transition metal compositions. The transition metal electron orbitals split under semiconductor crystal field. The electron ground states are used as qubits. The transitions between the ground states involve electron spin flip. The semiconductor and transition metal compositions may be further included in optical cavities to facilitate quantum information processing. Quantum logic operations may be performed using single color or two color coherent resonant optical excitations via an excited electron state.
    Type: Grant
    Filed: July 29, 2019
    Date of Patent: August 18, 2020

  • Patent number: 6625469
    Abstract: There is provided a radio telephone having an arcuate support (114, 1008, 1506) positioned at an upper portion (104, 1002, 1502) of the radio telephone's housing (102) for attachment to a loop-shaped object, such as a belt loop, bag strap and the like. The arcuate support (114, 1008, 1506) includes a first section (110, 1004, 1504) that is stationary relative to the housing (102), and a second section (112, 1006, 1506) that pivots away from the first section (110, 1004, 1504) to open the support (114, 1008, 1506) and returns back to the first section (110, 1004, 1504) to close the support (114, 1008, 1506). Depending upon the embodiment of the radio telephone, the arcuate support (114, 1008, 1506) may open by moving the second section (112, 1006, 1506) inward from the first section (110, 1004, 1504), outward from the first section (110, 1004, 1504) or both inward and outward relative to the first section (110, 1004, 1504).
