Quantum Statistical Witness Indistinguishability
Shafik Nassar, Ronak Ramachandran
Statistical witness indistinguishability is a relaxation of statistical zero-knowledge which guarantees that the transcript of an interactive proof reveals no information about whi…

Quantum Search with In-Place Queries
Blake Holman, Ronak Ramachandran, Justin Yirka
Quantum query complexity is typically characterized in terms of XOR queries |x,y> to |x,y+f(x)> or phase queries, which ensure that even queries to non-invertible functions are uni…

PDQMA = DQMA = NEXP: QMA With Hidden Variables and Non-collapsing Measurements
Scott Aaronson, Sabee Grewal, Vishnu Iyer +2
We define and study a variant of QMA (Quantum Merlin Arthur) in which Arthur can make multiple non-collapsing measurements to Merlin's witness state, in addition to ordinary collap…
