Space-Time Circuit-to-Hamiltonian Construction and Its Applications
, 2014 The circuit-to-Hamiltonian construction translates dynamics (a quantum circuit and its output) into statics (the groundstate of a circuit Hamiltonian) by explicitly defining a quantum register for a clock.

Entropy flow in near-critical quantum circuits
, 2019 Near-critical quantum circuits are ideal physical systems for asymptotically large-scale quantum computers, because their low energy collective excitations evolve reversibly, effectively isolated from the environment.
