Abstract
An always-on, exchange-only (AEON) qubit is comprised of three two-level systems (e.g., semiconductor quantum dot or other spin encoded qubit) and can be operated at a 'sweet spot' during both single qubit and two-qubit gate operations. The 'sweet spot' operation is immune to variations in noise with respect to nontrivial detuning parameters defining the AEON. By operating at the “sweet spot,” both single and two-qubit gate operations can be performed using only exchange pulses (e.g., DC voltage pulses applied to tunneling gates).
