Efficient Synthesis of Multi-Controlled Toffoli Gates with Ternary Clifford Gates
Amit Saha, Francesco Arzani
Temporary occupation of qutrit levels can reduce the width and depth required for binary circuit logic in quantum computing. We introduce an efficient intermediate-qutrit decomposi…
Quantum low-density lattice codes
Timo Hillmann, Jens Eisert, Francesco Arzani
Gottesman-Kitaev-Preskill (GKP) codes provide a family of promising schemes for encoding discrete quantum information (qudits) into infinite-dimensional bosonic modes based on math…
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…
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 c…
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…
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…
