Latest Patents

One of Girvin's latest patents is titled "Photon-number dependent Hamiltonian engineering for resonators." This work explores the potential of cavity resonators as resources for quantum technology. The research addresses the challenge of weak native nonlinear interactions in cavities, which are insufficient for achieving the level of quantum control necessary for complex operations. Girvin's investigation presents a scheme to engineer a target Hamiltonian for photonic cavities using ancilla qubits. By off-resonantly driving dispersively coupled ancilla qubits, he develops an optimized approach to create an arbitrary photon-number dependent Hamiltonian for the cavities while minimizing operational 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. The scheme can be implemented with coupled microwave cavities and transmon qubits in superconducting circuit systems.

Another notable patent involves "Techniques for quantum memory addressing and related systems and methods." This patent describes techniques for implementing a Quantum Random Access Memory (QRAM) by routing quantum information through multiple modes of a bosonic system. The configuration allows a single bosonic system to maintain quantum information across a large number of independent modes simultaneously. The operations performed on these modes enable the routing of quantum address values to the corresponding bits, ensuring that only the modes associated with the accessed addresses are altered. The stored bits can be classical bits or qubits, facilitating the extraction of desired correlated superpositions of the stored bit values.
