Advantages and limitations of quantum routing

We lower bound the circuit depth or time required for quantum routing in terms of spectral properties of graphs representing the architecture interaction constraints, and give a generalized upper bound for all simple connected $n$-vertex graphs.

Quantum routing with teleportation

We study the problem of implementing arbitrary permutations of qubits under interaction constraints in quantum systems that allow for arbitrarily fast local operations and classical communication (LOCC).

Entanglement bounds on the performance of quantum computing architectures

In this paper, we show that a quantity known as the isoperimetric number establishes a lower bound on the time required to create highly entangled states.

Unitary entanglement construction in hierarchical networks

We present numerical and analytical results on the speed at which large entangled states can be created on nearest-neighbor grids and hierarchy graphs. We also present a scheme for performing circuit placement on hierarchical quantum architectures.
