Technologies for closed-loop qubit calibration
Patent published on the 2026-07-01 in EP under Ref EP4769246 by INTEL CORP [US] (Levinger Run [us], Subramanian Sushil [us], Shumaker Evgeny [il])
Abstract: [0001] Technologies for closed-loop calibration of pulses to control spin qubits are disclosed. In an illustrative embodiment, calibration circuitry generates a pulse from a pulse generator. The pulse passes through a variable filter controlled by a filter parameter. The pulse is provided to a qubit, and the qubit is measured. Depending on the measured state of the qubit, the filter parameter can be changed. In this manner, the control pulses can be quickly and continuously calibrated. The calib[...]

Abstract: Recent experiments have discovered superconductivity in the ternary molybdenum pnictide materials A2Mo3As3 (A = K, Rb, Cs). In this work, we investigate the superconducting properties of the A2Mo3As3 family based on an effective five-band Hubbard model and using the fluctuation exchange approximation. By solving the linearized Eliashberg equation for various interaction parameters, we find that the spin-singlet and spin-triplet pairings dominate as the leading pairing symmetries in the weak and [...]
