A Dichotomy for MIP* in the Presence of Unital Noise
Yangjing Dong, Zhenyu Jiang, Minglong Qin +2
We study two-prover one-round quantum interactive proofs in which the provers share arbitrarily many copies of a noisy EPR pair. Prior work showed that if the shared state has…

Dimension-Free Approximate Tensorization of Quantum Hypercontractivity for Qudit Depolarizing Semigroups
Yangjing Dong, Li Gao, Fengning Ou +2
We prove approximate tensorization for hypercontractivity and logarithmic-Sobolev constants for a class of primitive reversible quantum Markov semigroups satisfying the positive of…
