Latest Patents

One of his latest patents focuses on photon-number dependent Hamiltonian engineering for resonators. This work addresses the challenge of weak native nonlinear interactions in cavity resonators, which are essential for quantum technology. Noh's research investigates a scheme to engineer a target Hamiltonian for photonic cavities using ancilla qubits. By off-resonantly driving dispersively coupled ancilla qubits, he has developed an optimized approach to engineer an arbitrary photon-number dependent Hamiltonian for the cavities while minimizing operation errors. This engineered Hamiltonian has various applications, including canceling unwanted cavity self-Kerr interactions, creating higher-order nonlinearities for quantum simulations, and designing quantum gates that are resilient to noise. His scheme can be implemented with coupled microwave cavities and transmon qubits in superconducting circuit systems.

Another notable patent involves 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. This method ensures that the cat qubits are rotated in the same manner while performing gates, regardless of the state of the transmon ancilla qubit.
