Polynomial-time thermalization and Gibbs sampling from system-bath couplings
Samuel Slezak, Matteo Scandi, Álvaro M. Alhambra +2
Many physical phenomena, including thermalization in open quantum systems and quantum Gibbs sampling, are modeled by Lindbladians approximating a system weakly coupled to a bath. U…

Quantum Approximate Counting with Additive Error: Hardness and Optimality
Mason L. Rhodes, Sam Slezak, Anirban Chowdhury +1
Quantum counting is the task of determining the dimension of the subspace of states that are accepted by a quantum verifier circuit. It is the quantum analog of counting the number…
