摘要： The disclosure describes aspects of using multiple species in trapped-ion nodes for quantum networking. In an aspect, a quantum networking node is described that includes multiple memory qubits, each memory qubit being based on a 171Yb+ atomic ion, and one or more communication qubits, each communication qubit being based on a 138Ba+ atomic ion. The memory and communication qubits are part of a lattice in an atomic ion trap. In another aspect, a quantum computing system having a modular optical architecture is described that includes multiple quantum networking nodes, each quantum networking node including multiple memory qubits (e.g., based on a 171Yb+ atomic ion) and one or more communication qubits (e.g., based on a 138Ba+ atomic ion). The memory and communication qubits are part of a lattice in an atomic ion trap. The system further includes a photonic entangler coupled to each of the multiple quantum networking nodes.

摘要： The disclosure provides an atomic object trap apparatus and a method of operating such. The atomic object trap apparatus comprises two or more radio frequency (RF) electrodes formed concentrically in a substantially elliptical shape; and three or more trapping and/or transport (TT) electrode sequences formed concentrically in a substantially elliptical shape. The two or more RF electrodes and the three or more TT electrode sequences define a substantially elliptically-shaped atomic object trap. At least one TT electrode sequence of the three or more TT electrode sequences is disposed concentrically between the two or more RF electrodes. Each RF electrode and TT electrode sequence is elliptically shaped such that each comprises two substantially parallel longitudinal regions and two arc-spanning beltway regions, the four regions forming a substantially elliptical shape. The method is directed to operating a quantum computing system comprising an example atomic object trap apparatus.

摘要： A method of quantitative mass analysis of precursor species of different mass-to-charge (m/z) ratios from a single or the same ion injection event is disclosed. A plurality of precursor ion species having different respective m/z ratios are introduced into a mass spectrometer at the same time. The precursor ion species are isolated. A first subset of the isolated precursor ions having a first m/z ratio is fragmented and analyzed. A second subset of the isolated precursor ions having a second m/z ratio is fragmented and analyzed. A first mass spectrum is generated for the fragment ions of the first subset of precursor ions, and a second mass spectrum is generated for the fragment ions of the second subset of precursor ions.

摘要： A mass spectrometer includes a radio frequency ion trap; and a controller. The controller is configured to cause an ion population to be injected into the radio frequency ion trap; supply a first isolation waveform to the radio frequency ion trap for a first duration, and supply a second isolation waveform to the radio frequency ion trap for a second duration. The first isolation waveform has at least a first wide notch at a first mass-to-charge ratio, and the second isolation waveform has at least a first narrow notch at the first mass-to-charge ratio. The first and second isolation waveforms are effective to isolate one or more precursor ions from the ion population.

摘要： An off-axis ion transport optical system (20) including a front-stage quadrupole ion guide (21), a rear-stage quadrupole ion guide (22), and an ion deflector (23) is disposed inside an intermediate vacuum chamber (2) in a stage next to an ionization chamber (1) maintained at an atmospheric pressure. Both of the quadrupole ion guides (21 and 22) have the same configuration as that of a conventional ion guide that transports ions while trapping the ions using a radio-frequency electric field. The ion deflector (23) includes a pair of parallel flat electrodes (231 and 232) and deflects ions using a direct-current electric field. By causing the deflected ions to reach the ion receiving range of the rear-stage quadrupole ion guide (22), it is possible to efficiency introduce ions while deflecting the ions. Meanwhile, the ions and neutral particles are separated from each other in the ion deflector (23). This provides an off-axis structure ion transport optical system that achieves a high ion transmission efficiency with a simple structure.

摘要： A radio-frequency voltage generator includes a first DC power supply for generating first direct-current voltage; a second DC power supply for generating second direct-current voltage; a transient alternating voltage generation circuit for generating a transient alternating voltage having a cycle shorter than a cycle of the radio-frequency voltage and having a voltage value oscillating between the first direct-current voltage and the second direct-current voltage; and a voltage switch section for switching voltages from the first direct-current voltage, to the transient alternating voltage, to the second direct-current voltage, and to the transient alternating voltage in this order, wherein the voltage switch section switches the voltages applied to the load so that the transient alternating voltage oscillates a half-integer of times starting with an initial value having the value of the direct-current voltage applied immediately before the switching, the half-integer being equal to or greater than 1.5.

摘要： A mass or mass to charge ratio selective ion trap is disclosed which directs ions into a small ejection region. A RF voltage acts to confine ions in a first (y) direction within the ion trap. A DC or RF voltage acts to confine ions in a second (x) direction. A quadratic DC potential well acts to confine ions in a third (z) direction within the ion trap. The profile of the quadratic DC potential well progressively varies along the second (x) direction.
