Hybrid spatiotemporal architectures for universal linear optics

2019 · Physical Review A

We present two hybrid linear-optical architectures that simultaneously exploit spatial and temporal degrees of freedom of light to effect arbitrary discrete unitary transformations. Our architectures combine the benefits of spatial implementations of linear optics, namely, …

Universal quantum computation with optical four-component cat qubits

2021 · arXiv (Cornell University)

We propose a teleportation-based scheme to implement a universal set of quantum gates with a four-component cat code, assisted by appropriate entangled resource states and photon number resolving detection. The four-component cat code features the …
