    摘要： The present disclosure relates to a laser apparatus for excitation of Strontium atoms in a quantum processor. It comprises a fiber laser source (111) for emitting light at a wavelength of about 1064 nm; an Er-doped fiber laser (112) for emitting light at a wavelength of about 1534 nm; a fiber-coupled SHG device (114) configured to receive said light at about 1064 nm to produce light at a wavelength of about 532 nm; a fiber-coupled DFG device (113) configured to receive said light at about 1534 nm and said light at about 532 nm and produce light at a wavelength of about 813 nm; a fiber-coupled SFG device (115) configured to receive said light at about 813 nm and light at about 1064 nm partially transmitted by said fiber-coupled SHG device and produce light (15) at a wavelength of about 461 nm and partially transmit the light at about 813 nm. The transmitted light at about 813 nm (10) is configured to produce a dipolar trapping beam and the light at about 461 nm is configured to produce first MOT laser beams.

    摘要： There is presented a method for outputting at least first and second electromagnetic, EM, signals for respectively interacting with spatially separated first and second matter particles in an interaction region. The matter particles act as qubits for use with a quantum computation. The interaction of the EM signals with the qubits is associated with a Hamiltonian operator comprising at least a first and a second element. EM radiation is generated using an EM source. The EM radiation is modulated by the with a first modulator configured to temporally modulate the EM radiation within a computation time period. The first modulator is associated with the first element of the Hamiltonian operator. The EM radiation is modulated with a second modulator configured to modulate the EM radiation such that the first EM signal is spatially separate to the second EM signal in the interaction region. The second modulator is associated with the second element of the Hamiltonian operator. The one or more EM signals are output based on the modulated EM radiation, to the plurality of matter particles.

    摘要： A method of using a quantum-based system for outputting a variable for use with a first problem. A set of parameters is determined, for a second problem, for running the quantum-based system. The set of parameters are associated with at least one or more variables of the version of the second problem and enable the quantum-based system to output a plurality of solutions to the second problem. Each of the plurality of solutions is associated with a common set of quantum states of the quantum-based system and a different value of at least one of the said the variables of the second problem. The quantum-based system is run using at least the determined set of parameters to identify a set of one or more of the qubits corresponding to at least one of the solutions to the second problem. At least one solution to the second problem is determined to be a new variable for the first problem. The new variable is output for use with the version of the first problem.
