Quantum enhancement of signal-to-noise ratio for arbitrary coherent states using heralded linear amplifiers
2017
We present an experimental enhancement of signal-to-noise ratio for arbitrary coherent states using a noise-reduced linear amplifier that profitably combines a heralded measurement-based noiseless linear amplifier and a deterministic linear amplifier. The concatenation of two …

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 …
