    摘要： A nuclear radiation detection system using narrowband UV crystal filters is disclosed. Since the photons produced during the decay of β- and γ-radiation can be detected in the spectral range of about 200-350 nm (the ultraviolet range), UV filter based photo sensors are utilized for detection. The nuclear radiation detection system comprises an optical assembly capable of focusing on a source of radiation, a UV filter assembly having a narrowband UV crystal filter and positioned to receive light transmitted through the optical assembly, and a light detector positioned to receive light transmitted through the UV filter assembly. The narrowband UV crystal filter is fabricated from crystals selected from the group consisting of nickel fluorosilicate, nickel fluoroborate, and potassium nickel sulfate. The nickel fluorosilicate, nickel fluoroborate, and potassium nickel sulfate may be doped to achieve even narrower band filter. The radiation detection system can be used to monitor contamination in a nuclear plant or a nuclear waste dump site. It may also be used for surveillance of contamination in case of a nuclear accident.

    摘要： Systems and methods are provided for a tunable transmon qubit. The qubit includes a first Josephson junction on a first path between a transmission line and a circuit ground and second and third Josephson junctions arranged in parallel with one another on a second path between the transmission line and the circuit ground to form a direct current superconducting quantum interference device (DC SQUID). The DC SQUID is in parallel with the first Josephson junction. A capacitor is arranged in parallel with the first Josephson junction and the DC SQUID on a third path between the transmission line and the circuit ground as to form, in combination with the first path, an outer loop of the tunable transmon qubit. A bias circuit is configured to provide a constant bias flux to one of the DC SQUID and the outer loop of the tunable transmon qubit.

    摘要： Systems and methods are provided for performing a quantum error correction. An error correction is performed on each of a plurality of qubit sets restore a desired basis state of the qubit set. Each qubit set corresponds to an associated logical qubit. A number of corrected qubits at each of the plurality of qubit sets are recorded. A first set of the plurality of logical qubits having a first state and a second set of the plurality of logical qubits having a second state are determined. One of the first set of logical qubits and the second set of logical qubits are corrected according to the recorded numbers of corrected qubits.

    摘要： A quantum logic gate is formed from multiple qubits coupled to a common resonator, wherein quantum states in the qubits are transferred to the resonator by transitioning a classical control parameter between control points at a selected one of slow and fast transition speeds, relative to the characteristic energy of the coupling, whereby a slow transition speed exchanges energy states of a qubit and the resonator, and a fast transition speed preserves the energy states of a qubit and the resonator.
