The Computational Advantage of MIP* Vanishes in the Presence of Noise
Yangjing Dong, Honghao Fu, Anand Natarajan +3
Quantum multiprover interactive proof systems with entanglement MIP* are much more powerful than its classical counterpart MIP (Babai et al. '91, Ji et al. '20): while MIP = NEXP,…
Communication Complexity of Common Randomness Generation with Isotropic States
Yangjing Dong, Penghui Yao
This paper addresses the problem of generating a common random string with min-entropy k using an unlimited supply of noisy EPR pairs or quantum isotropic states, with minimal comm…
Hypercontractivity for Quantum Erasure Channels via Variable Multipartite Log-Sobolev Inequality
Zongbo Bao, Yangjing Dong, Fengning Ou +1
We prove an almost optimal hypercontractive inequality for products of quantum erasure channels, generalizing the hypercontractivity for classical binary erasure channels. To our k…
