Efficient Depth--Ancilla Tradeoffs for Hamming Weight Computation and Symmetric Boolean Functions
Wei Zi, Pei Yuan, Junhong Nie +1
Hamming weight computation maps an -bit input to the number of ones it contains. It is a basic subroutine in quantum computing, and the core building block for symmetric Boolean…
Approximating the Trace Distance Between Product Quantum States
Kun He, Dimitrios Myrisiotis, Junhong Nie +1
We study the trace distance \[D_{\mathrm{tr}}(ρ,σ) =\frac12\|ρ-σ\|_1, ρ=\bigotimes_{i=1}^nρ_i,\quad σ=\bigotimes_{i=1}^nσ_i, \] when the two exponentially large states are specifie…
