Latest Patents

Keller's latest patents include "Quantum codes implemented using cat data qubits and transmon ancilla qubits." This patent discloses systems and methods for implementing a quantum code using cat qubits as data qubits and transmon qubits as ancilla qubits. In some embodiments, a three-level transmon is utilized, and Chi-matching is performed to determine dispersive coupling coefficients between the cat qubits and the first and second excited states of the transmon qubits. The Chi-matching ensures that the cat qubits are rotated in the same manner while performing gates, regardless of whether a given transmon ancilla qubit remains in a second excited state or has decayed to a first excited state. Another patent, "Method for producing transmon qubit and lithium niobate resonator on the same substrate," describes a fabrication method where an electromechanical resonator made out of lithium niobate is fabricated on the same substrate as a Josephson Junction-based transmon qubit. This method preserves the quality of the substrate, enabling the fabrication of high-performance qubits.
