Abstract: 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.

Abstract: There is presented, a system (2) for forming a plurality of focussed electromagnetic, EM, radiation regions, for interacting with one or more matter particles; the matter particles act as qubits in a quantum computation. The system comprising: I) a source assembly (8) comprising a plurality of emitters (10) wherein each emitter is configured to generate and output EM radiation (12); the plurality of emitters comprising at least a first emitter and a second emitter; the source assembly configured to independently change the intensity of EM radiation output from the assembly from the first emitter and the second emitter; II) a focussing assembly comprising one or more EM focussing elements; the focussing assembly configured to focus EM radiation to form: a first focussed EM region, of the plurality of EM regions (14), using EM radiation output from the first emitter; a second focussed EM region, of the plurality of EM regions, using EM radiation output from the second emitter. The first EM region occupying a different portion of space to the second EM region; wherein: a) the source assembly is configured such that the first and second emitters are upon a unitary device; and/or, b) the EM regions form one or more traps for the matter particles.

Abstract: There is presented a system (500) for forming electromagnetic, EM, radiation for interacting with a plurality of matter particles (504) in an interaction region (516). The matter particles acting as qubits in a quantum computation. The system comprising: a plurality of EM emitters (506, 506a, 506b) for generating EM radiation (508a, 508b), the system configured to form an EM intensity distribution (514a, 514b) of the EM radiation in the interaction region for each of the EM emitters; the plurality of EM emitters comprises: i) a first set of two or more of the plurality of EM emitters associated with a first matter particle of the plurality of matter particles; and ii) further EM emitters associated with one or more different matter particles to the first matter particle. The system is further configured such that the EM radiation generated by each of the EM emitters of the first set forms an intensity distribution covering a different portion of the interaction region to the EM distributions of: a) the other EM emitters within the first set; and b) the further EM emitters.
