Fisher information as a probe of spacetime structure: Relativistic quantum metrology in (A)dS
Haoxing Du, Robert B. Mann
Relativistic quantum metrology studies the maximal achievable precision for estimating a physical quantity when both quantum and relativistic effects are taken into account. We stu…

Postquantum common-cause channels: the resource theory of local operations and shared entanglement
David Schmid, Haoxing Du, Maryam Mudassar +3
We define the type-independent resource theory of local operations and shared entanglement (LOSE). This allows us to formally quantify postquantumness in common-cause scenarios suc…

Emergent geometry from stochastic dynamics, or Hawking evaporation in M(atrix) theory
Haoxing Du, Vatche Sahakian
We develop an microscopic model of the M-theory Schwarzschild black hole using the Banks-Fischler-Shenker-Susskind Matrix formulation of quantum gravity. The underlying dynamics is…
