I study a specific type of flaw in superconducting quantum computing circuits (Qubits) called a two level system (TLS). Most superconducting qubits can only hold their information for a fraction of a millisecond because the information is transferred to TLS and then lost. Solving the TLS problem can greatly improve coherence times, allow for more compact devices, and improve superconducting circuits for other applications like microwave detectors.
