Fault-Resilience of Dissipative Processes for Quantum Computing
James Purcell, Abhishek Rajput, Toby Cubitt
Dissipative processes have long been proposed as a means of performing computational tasks on quantum computers that may be intrinsically more robust to noise. In this work, we pro…

Chaitin Phase Transition
James Purcell, Zhi Li, Toby Cubitt
We construct a family of Hamiltonians whose phase diagram is guaranteed to have a single phase transition, yet the location of this phase transition is uncomputable. The Hamiltonia…
