Improved GKP magic states from error-corrected non-Gaussian quantum states
Sharon David, Jack Davis, Ulysse Chabaud +1
Gate teleportation, together with magic state distillation, is a promising route towards fault-tolerant, universal computation. In the context of bosonic quantum computation, Barag…
Detecting quantum non-Gaussianity with a single quadrature
Clara Wassner, Jack Davis, Sacha Cerf +2
Full reconstruction of quantum states from measurement samples is often a prohibitively complex task, both in terms of the experimental setup and the scaling of the sample size wit…
A hidden bottleneck in classical and quantum linear reservoir computing
Johannes Nokkala, Federico Centrone, Francesco Arzani
We identify a hidden bottleneck in the information processing capacity of linear reservoir computers. When the measured features evolve linearly in the reservoir and the output is…
On the complex zeros of the wavefunction
Sacha Cerf, Clara Wassner, Jack Davis +2
The Schrödinger wavefunction is ubiquitous in quantum mechanics, quantum chemistry, and bosonic quantum information theory. Its zero-set for fermionic systems is well-studied and…
Can effective descriptions of bosonic systems be considered complete?
Francesco Arzani, Robert I. Booth, Ulysse Chabaud
Bosonic statistics give rise to remarkable phenomena, from the Hong-Ou-Mandel effect to Bose-Einstein condensation, with applications spanning fundamental science to quantum techno…
