- Abstract
- Circulators are crucial components in quantum computers that ensure that quantum information is coherently transported. Current commercial circula- tors are too bulky because they use permanent magnets, so producing chip- scale circulators is necessary to feasibly scale up the size of quantum computers using superconducting qubits. Using a model inspired by a paper by Rudner [2], I have designed a lattice circuit that will produce non-reciprocity, which is the property required for proper circulation. These lattice circuits are able to produce circulation because they have periodically time-dependent bonds that control interactions between the sites in the lattice. In this thesis, I first theoretically analyze two similar lattice circuits and show that they can both produce non-reciprocity. Finally, I experimentally demonstrate non-reciprocity in a 2 by 2 lattice circuit at room temperature. This experimental verification of circu- lation motivates future testing of larger lattices and building superconducting versions of the circuit to create chip-scale circulators.
