Charge-noise-insensitive gate operations for always-on, exchange-only qubits

1 min read

Proposes the AEON (Always-on Exchange-Only) qubit: a variant of the three-spin exchange-only qubit designed for always-on exchange coupling, eliminating the need for dynamic barrier gate control. Uses a symmetric operating point where charge noise is first-order suppressed.

Key Results

  • Three-spin qubit with permanent exchange coupling
  • Operates at symmetric charge-noise sweet spot
  • All-electrical control via asymmetric detuning pulses
  • Eliminates the need for rapid on/off switching of exchange
