A Constant Rate Quantum Computer on a Line
Craig Gidney, Thiago Bergamaschi
We prove by construction that the Bravyi-Poulin-Terhal bound on the spatial density of stabilizer codes does not generalize to stabilizer circuits. To do so, we construct a fault t…

Simulated Quantum Annealing is Efficient on the Spike Hamiltonian
Thiago Bergamaschi
In this work we study the convergence of a classical algorithm called Simulated Quantum Annealing (SQA) on the Spike Hamiltonian, a specific toy model Hamiltonian for quantum-mecha…
