Abstract
Systems and techniques that facilitate controlling TLS via on-chip filtering to prevent qubit energy loss are provided. In various embodiments, a system can comprise a quantum device including a qubit device on a substate. In various embodiments, the quantum device can include an electrode placed in proximity to the qubit device. In various embodiments, an electrical filter can be connected to the electrode. In various embodiments, the quantum device can comprise a voltage source that can be connected to the electrode via the electrical filter. In various embodiments, the voltage source can control a voltage to the electrode to shift a resonant frequency of one or more defects to reduce two level system (TLS) impact on the qubit device.
