Protocol for Control-NOT and Control-PHASE gate between a Quantum Memory and Gottesman-Kitaev-Preskill Encoded Photonic Qubit
This innovation is a proposed interface between Gottesman-Kitaev-Preskill (GKP) qubit states (which are optimal for qubit transmission in quantum computing) and quantum memories (which can support long coherence and storage times) based on a cavity-mediated controlled displacement gate. The inventors prescribe optimal regimes of operation for high-quality...

Zero-Added-Loss Entangled Photon Multiplexing Source
This technology is a scheme for optical entanglement distribution in quantum networks based on a quasi-deterministic entangled photon pair source. By combining heralded photonic Bell pair generation with spectral mode conversion to interface with quantum memories, the scheme eliminates switching losses due to multiplexing. Based on numerical analyses,...

Non-Gaussian Photonic State Engineering with the Quantum Frequency Processor
This technology is a means of generating non-Gaussian quantum states in light for use in quantum computing. Non-Gaussian quantum states are a subset of quantum states that enable operations that would not be possible with Gaussian states in quantum computers. As a result, they bring a lot of potential value to quantum computing. However, non-Gaussian...
