All-optical cat-code quantum error correction
Jacob Hastrup, Ulrik Lund Andersen
The cat code is a promising encoding scheme for bosonic quantum error correction as it allows for correction against losses--the dominant error mechanism in most bosonic systems. H…
Slowing quantum decoherence of oscillators by hybrid processing
Kimin Park, Jacob Hastrup, Jonas Schou Neergaard-Nielsen +3
Quantum information encoded into superposition of coherent states is an illustrative representative of practical applications of macroscopic quantum coherence possessing. However,…
Unconditional preparation of squeezed vacuum from Rabi interactions
Jacob Hastrup, Kimin Park, Radim Filip +1
Squeezed states of harmonic oscillators are a central resource for continuous-variable quantum sensing, computation and communication. Here we propose a method for the generation o…
Cubic phase gates are not suitable for non-Clifford operations on GKP states
Jacob Hastrup, Mikkel V. Larsen, Jonas S. Neergaard-Nielsen +2
With the Gottesman-Kitaev-Preskill (GKP) encoding, Clifford gates and error correction can be carried out using simple Gaussian operations. Still, non-Clifford gates, required for…
Measurement-free preparation of grid states
Jacob Hastrup, Kimin Park, Jonatan Bohr Brask +2
Quantum computing potentially offers exponential speed-ups over classical computing for certain tasks. A central, outstanding challenge to making quantum computing practical is to…
Deterministic generation of a four-component optical cat state
Jacob Hastrup, Jonas Schou Neergaard-Nielsen, Ulrik Lund Andersen
The four-component cat state represents a particularly useful quantum state for realizing fault-tolerant continuous variable quantum computing. While such encoding has been experim…
