Stroboscopic Stabilization of Cat Qubits
Timo Hillmann, Franco Nori, Fernando Quijandría
Dissipatively stabilized cat qubits provide a promising route toward fault-tolerant quantum computation, exhibiting exponential suppression of bit-flip errors with increasing phase…
Observation of Genuine Tripartite Non-Gaussian Entanglement from a Superconducting Three-Photon Spontaneous Parametric Down-Conversion Source
Benjamin Jarvis-Frain, Andy Schang, Fernando Quijandría +5
The generation of entangled photons through Spontaneous Parametric Down-Conversion (SPDC) is a critical resource for many key experiments and technologies in the domain of quantum…
Quantum Error Correction with Superpositions of Squeezed Fock States
Yexiong Zeng, Fernando Quijandría, Clemens Gneiting +1
Bosonic codes, leveraging infinite-dimensional Hilbert spaces for redundancy, offer great potential for encoding quantum information. However, the realization of a practical contin…
Tripartite Genuine Non-Gaussian Entanglement in Three-Mode Spontaneous Parametric Downconversion
Andrés Agustí, C. W. Sandbo Chang, Fernando Quijandría +3
We show that the states generated by a three-mode spontaneous parametric downconversion (SPDC) interaction Hamiltonian possess tripartite entanglement of a different nature to othe…
