We examine continuous-variable gate teleportation using entangled states made from pure
product states sent through a beam splitter. We show that such states are Choi states for a …

Quantum computing is a disruptive paradigm widely believed to be capable of solving
classically intractable problems. However, the route toward full-scale quantum computers is …

A quantum computer with low-error, high-speed quantum operations and capability for
interconnections is required for useful quantum computations. A logical qubit called …

The immense scalability of continuous-variable cluster states motivates their study as a
platform for quantum computing, with fault tolerance possible given sufficient squeezing and …

One-way quantum computing is experimentally appealing because it requires only local
measurements on an entangled resource called a cluster state. Record-size, but …

Terahertz spectral acquisition has a fundamental limitation in implementation due to long
experimental acquisition time. The long experimental acquisition time in terahertz spectral …

Due to its unique scalability potential, continuous-variable quantum optics is a promising
platform for large-scale quantum computing. In particular, very large cluster states with a two …

Continuous-variable cluster states allow for fault-tolerant measurement-based quantum
computing when used in tandem with the Gottesman-Kitaev-Preskill (GKP) encoding of a …

Universal quantum computation using photonic systems requires gates the Hamiltonians of
which are of order greater than quadratic in the quadrature operators. We first review …

A prerequisite for universal quantum computation and other large-scale quantum
information processors is the careful preparation of quantum states in massive numbers or of …
