Space-bounded quantum interactive proof systems

François Le Gall, Yupan Liu, Harumichi Nishimura +1

We introduce two models of space-bounded quantum interactive proof systems, $QIPL$ and $QI P_{U} L$ . The $QI P_{U} L$ model, a space-bounded variant of quantu…

On estimating the trace of quantum state powers

Yupan Liu, Qisheng Wang

We investigate the computational complexity of estimating the trace of quantum state powers $tr (ρ^{q})$ for an $n$ -qubit mixed quantum state $ρ$ , given its state-preparation c…
