PULSED STARK TONES FOR COLLISION MITIGATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18461589 titled 'PULSED STARK TONES FOR COLLISION MITIGATION

Simplified Explanation

Techniques for using stark tone pulses to mitigate cross-resonance collision in qubits are presented. A tone management component can control application of pulses to qubits by a tone generator component to mitigate undesirable frequency collisions between qubits. The tone generator component (TGC) can apply an off-resonant tone pulse to a qubit during a gate to induce a stark shift. TGC can apply a cross-resonance tone pulse to a control qubit at a frequency associated with the qubit, wherein the frequency can be stark shifted based on the off-resonant tone pulse. The qubit can be a target qubit, the control qubit itself, or a spectator qubit that can be coupled to the target qubit or the control qubit. The gate can be a cross-resonance gate, a two-qubit gate, or a measurement gate that can utilize an echo sequence, a target rotary, or active cancellation.

  • Tone management component controls application of pulses to qubits to prevent frequency collisions.
  • Tone generator component applies off-resonant tone pulses to induce stark shift in qubits during gates.
  • Cross-resonance tone pulses are applied to control qubits at a frequency associated with the qubit.
  • The frequency of the control qubit can be stark shifted based on the off-resonant tone pulse.
  • Qubit can be a target qubit, control qubit, or spectator qubit coupled to the target or control qubit.
  • Gates can be cross-resonance gates, two-qubit gates, or measurement gates utilizing echo sequence, target rotary, or active cancellation.
