A simple proof of unitary parallelization via port-based teleportation
Anurag Anshu, Quynh T. Nguyen
Port-based teleportation (PBT) is a variant of quantum teleportation that does not require corrections on the teleported state: starting with shared EPR states, Alice can telep…
Learning quantum Gibbs states locally and efficiently
Chi-Fang Chen, Anurag Anshu, Quynh T. Nguyen
Learning the Hamiltonian underlying a quantum many-body system in thermal equilibrium is a fundamental task in quantum learning theory and experimental sciences. To learn the Gibbs…
On the complexity of unique quantum witnesses and quantum approximate counting
Anurag Anshu, Jonas Haferkamp, Yeongwoo Hwang +1
We study the long-standing open question on the power of unique witnesses in quantum protocols, which asks if , a variant of whose accepting witn…
Circuit-to-Hamiltonian from tensor networks and fault tolerance
Anurag Anshu, Nikolas P. Breuckmann, Quynh T. Nguyen
We define a map from an arbitrary quantum circuit to a local Hamiltonian whose ground state encodes the quantum computation. All previous maps relied on the Feynman-Kitaev construc…
